1. Peugeot Carburetor ServicePeugeot 1980 tiny

Welcome. Here is service information for 1976-1980 Peugeot 102 and 103 moped carburetors (US models).

These carburetors are French made, by Gurtner, size 12mm, 10mm, or 8.5mm for different speed versions. They can be quick-serviced without carb removal. The main jet is the brass hexagonal slot head facing the right side, at the bottom. It is also a drain plug for quick flushing. If you are out riding and your main jet gets clogged, causing the engine to not run, you can easily remove the jet with just a key, coin or screwdriver, blow it out with your lips, put it back, restart and continue your ride. That is one of Peugeot’s best features. 

Peugeot Carb Diagram

How it Works

There are three spray holes. When the engine is idling, the throttle slide is down, and the first two spray holes are shielded from the moving air. When the throttle is opened, the slide is up and out of the way. All three spray holes are active. The first (main) spray hole flows about 3 times as much as the second (middle) spray hole, which in turn flows about 3 times as much as the third (idle) spray hole. So the idle uses about one ninth as much gas, roughly. When it gets clogged the net flow at full throttle is about 8/9 or of normal. So it will still run OK with a clogged idle jet.   

An automatic float lets in fuel to the reservoir when needed.

Removing the Carburetor

1. Turn the gas valve (petcock) off. With one finger pressing down hard on the float top, so it does not lift up, twist and pull on the fuel hose to disconnect it from the carburetor. If the top is not held down, pulling on the fuel hose can bend the float needle when the lid lifts. Many Peugeot floats have been damaged in this way.

2. Leave both (choke and throttle) cable pinch bolts alone. Disconnect the choke cable, remove the phillips screw on top, and lift out the throttle slide. Notice the round throttle slide has a little prong on top that slides into a slot in the carburetor. You will need to remember that during re-assembly.

3. Loosen the mount clamp nut (10mm hex), then rotate the carburetor assembly gently back and forth, with both hands holding the carburetor, not the air filter box, while pulling rearward. Then wiggle it free.

Servicing the Carburetor 

The normal service consists of cleaning out all tar, rust, and corrosion. After disassembly, carb cleaner spray or parts dip is used to clean off tar and varnish. Anything plastic or rubber is not allowed to come in contact with the carb solvent. Scraping with small screwdrivers, knives, and wire brushes and/or wire wheels are usually needed on the float chamber walls and floor. A small drill bit is twisted, by fingers, in the guide hole at the bottom center of the float bowl, to lift out the fine rust powder that builds up there. Compressed air and carb spray are used to clean out and check all passageways. Seeing the spray enter and exit a passageway tells if it is open, even if you cannot visually see through it, like when there is a “bend in the tunnel”.

Testing with Carb Spray

Carefully (wear goggles) shoot carb spray into the froth air inlet in front below the venturi. There should be “three geysers” or jets of spray shooting out of 1) the main spray hole, 2) the large middle spray hole in the floor, and 3) the small idle spray hole in the floor.

Most of the time, on a bike that has been sitting for years, the idle jet (restriction) is blocked, causing the engine to not idle. When that happens, only the first two spray holes active in the carb spray test, instead of all three. The result is the engine will start and run fine, but won’t idle for over 2 or 3 seconds. Using the choke will compensate a little. Soaking the carburetor does not usually clean out the idle restriction hole, and neither does carb spray. The brass diffuser is pressed tightly into a single-ended hole. The only remedy is to drill a new one.

Drilling a New Idle Hole

Peugeot Carb Before and After DrillingThis is for when the carb spray test shows only the first two spray holes active. The careful and delicate drilling procedure uses a #71 drill bit, chucked in a pin vise, chucked in a hand held drill. The #71 is the thinnest drill that is long enough to reach horizontally from the front face back to the third vertical hole. A #72 is a little thinner and shorter, but still works if it is not inserted too deep in the pin vise chuck. A #70 drill is a little bigger and longer, but still works. Already the idle mixture, and mid-throttle mixture, are being made richer by drilling with a #71. On an old moped that is a good thing, because various small air leaks are compensated for. With a too rich idle mixture, the engine will stumble after waiting for a long red light, when the throttle is first opened. So a bigger drill size makes that bad behavior.

Use a half drop of oil and a sharp drill. Dull drill bits can get hot, melt in place, or veer off to one side, and then break off in the hole. Then there is no fixing that. You are drilling, blindly, into a round thing, so the drill wants to go to either side. Try to keep the drill centered and parallel to the horizontal tunnel front to rear.  It takes about 5-10 seconds to drill through each wall. After the drilling through the first wall of the diffuser, the bit breaks into the open vertical tunnel, and then encounters the second brass wall. Once through that, the horizontal tunnel is open for the rest of the way. Check the idle circuit before and after drilling, to verify that the idle spray hole did in fact get cleaned and is now working. Other things (air leaks) can cause the engine to not idle, like worn out piston rings and cylinder walls, and leaking crank seals or a stuck-open reed valve.

Restoring the Float

The float is a hollow plastic bulb type, with a 1.5mm thick brass rod pressed through it. The top end of the rod or needle has a precise cone shaped tip. The float needle tip gets worn, or the shaft gets bent. Then the float overflows and fuel drips out of the bottom of the air filter box.

Most of the time, the float will need regrinding of the tip, and maybe also some straightening of the needle shaft. Check to see if the needle is close to 37.8mm in length, the lower part sticks out 5.7mm, and the upper part is 11.9mm. If the bulb needs moving, hold one end of the float needle against the side of a table, while pushing on opposite sides of the bulb with both thumbs. If the needle moves too easy, it might leak fuel into the bulb, so then seal the ends with fuel proof sealant or epoxy, like below.

Shake it to see if it has any fuel inside the bulb. That would make it sink. Evacuate the fuel with compressed air and seal the needle holes with fuel proof sealant (like Kreem tank sealer or epoxy), without adding too much weight.

Chuck the bottom blunt end of the float needle into a hand drill. Spin it to check for trueness. If it is perfectly straight, it will almost appear to be not spinning. If it is bent, then straighten it with a small needle nose pliers. Take small bends and study the result to learn where the pliers need to be for the next bend. 

Once the needle is straight, the tip can be sharpened. Machine or sharpen the perfect cone tip, by chucking the needle rod in a small drill and spinning it, at a constant angle and pressure but moving around, against a flat sheet of fine sandpaper, taped to the edge of a table. Follow that with super fine and then polish. Try to keep the needle as long as possible, by only removing what is necessary, and no more.

Peugeot Float SeatFinally polish the float valve seat in the float top. Use a spinning toothpick, in a drill, with metal polish (or car wax). Inspect the hole with a magnifier. Illuminate it from the side hole as shown on the right. See if there are any scratches in the tiny hole down in the bottom of the small hole.

Bryan of Myrons discovered in 2007 an extremely useful way to sometimes fix a leaking Peugeot float, in a matter of seconds, without removing the carburetor. Close the petcock and remove the jet from the bottom of the carburetor. Blast compressed air into the jet hole. This spins the float rapidly inside the float chamber. Like lapping engine valves, the circular rubbing tends to make the two things (needle and seat) more circular, and less likely to leak.

Welcome. This is from the big blue Motobecane Dealer Manual, section “Repair Operations Models 40, 50, 7”, pages 32-35. The original words are dark grey, and Myrons Mopeds added words are purple.

Don’t replace, restore!

Most importantly, the cleaning procedures in original manuals are for new machines. They say to use compressed air to blow out tiny holes, which does clean the holes perfectly on a new carburetor. But compressed air alone is not enough to clean most older carburetors. Carburetor spray solvent, scraping, brushing, and poking the holes with certain size wires or tiny drills, are normally needed cleaning techniques. That is because years of decomposed gasoline and oil, called varnish, or tar, have coated the inside of the carburetor and gas tank. In addition, moisture can corrode the metal, coating the zinc alloy white and the brass brown or green. Zinc or aluminum corrosion is best cleaned with scraping and vinegar. Brass things like float needles and seats can be lightly machined and then polished.


Removing the Carburetor:

Fig 1 Carb Removal

Fig 1 Carb Removal

1. Remove the side covers.

2. Close the fuel tap and disconnect the fuel hose from the carburetor.

3. Remove the air box from the carburetor.

4. Loosen the carburetor clamp bolt. (8mm hex)

5. Remove the carburetor from the inlet pipe.

6. (Top pull choke cable type) Loosen the top cover screw. Remove the cables, slides and top assembly.

7. (Top pull choke cable type) Remove the carburetor (fig. 1).

6. (Bottom pull choke cable type) Leave the cables alone. Continue the service with the carburetor next to the bike.

7. (Bottom pull choke cable type) OR loosen the choke cable pinch bolt on the left handlebar control lever. Loosen the top cover screw. Remove the cables slides and top asssembly. Remove the carburetor (fig. 1).


Installing the Carburetor

1. (Center mount carburetor type) Make sure the plastic bushing on the inlet pipe is in good condition, if so equipped.

2. Make sure the nuts securing the intake pipe to the cylinder are tightened to the correct torque (7 ft lbs) using a torque wrench and 10mm socket. If the intake pipe was removed make sure the mating surfaces are clean. Fit a new gasket.

3. Insert the throttle slide (note the position of the guiding pin) and the choke slide.

4. Fit the top cover and tighten the screw securing it.

5. Make certain that the throttle slide operates freely and fully opens when the throttle grip is fully opened. If necessary, screw the adjustment screw on the handlebar throttle control. It needs to be tight enough to lift the throttle slide in the carburetor fully, yet still have a little bit of slack (so the bike does not accelerate when the steering is turned to the side!) 

6. Fit the carburetor to the intake pipe and push fully home. (rotating gently back and forth) 

7. Position the carburetor body vertically.

8. Tighten mount clamp (8mm hex)

9. Connect the fuel hose

10. Final idle adjustment can be made with the engine running by screwing or unscrewing the idle adjustment screw on the left of the carburetor.

11. Fit the side covers.

1. Remove the float bowl cover using a 10mm wrench.

2. Check the paper gasket and o-ring.

3. Loosen the small “cleaning” screw (using a small phillips head screwdriver) or the plastic cap (fig 1 and 2).

4. Clear this pipe if necessary with an air stream.

5. Fit the screw or plastic cap. Apparently the US DOT did not allow the plastic caps, because none were ever on US models. Instead they had a larger cleaning screw, M4 instead of M3. That M4 screw is not listed in the MB USA parts catalogs. Neither is the plastic cap.

6. Check the float for good condition. Plastic (not brass) float bulbs slide up and down on the needle rod with considerable pressure (like with both thumbs pushing the bulb, with the needle pressed against a solid wall). If the bulb is too high, the float will overflow, causing a rich mixture and/or fuel leakage. If the bulb is too low, the engine will “starve” for fuel, at times of high demand. Check if the needle is nearly 41.4mm long, and position the bottom of the bulb to 7.0mm.  

MB float service

Straighten a bent needle with a small needle-nose pliers. Take small steps, study the result, and adjust the grip point, in order to not make a “dog leg”.

Machine or sharpen the perfect cone tip, by chucking the needle rod in a small drill and spinning it, at a constant angle and pressure but moving around, against a flat sheet of fine sandpaper, taped to the edge of a table. Follow that with super fine and then polish. Try to keep the needle as long as possible, by only removing what is necessary, and no more.

Check that the float moves up and down freely without touching the walls. Check for a bulge in the float chamber wall, where the air filter stud sometimes pokes through. 

7. Remove the fuel jet (8mm wrench or screwdriver) and clear it if necessary with an air stream. (fig 3). There are tiny drills, about drill number 75 and 74, that are the size perfect for cleaning out moped main jets. Any piece of wire thin and stiff enough will work, but only a size just smaller than the hole will clean it out completely, if it is coated with varnish. Even after soaking, it can still need “scraping”. A kinky wire can be a second best tool. A welder’s torch tip file is another way to clean tiny holes. So is a dentist’s root canal file.

8. Look into the hole for the small slot in the center and a large different slot in the outer collar. If you don’t see this then it might be a press-fit diffuser type carburetor, instead of the usual slide-fit type. If this is covered in white (zinc oxide), then use vinegar on it first to remove enough white to see where the screwdriver slot is.

9. (Slide fit diffuser types) Apply a drop of oil to the lowest threads. With a 6mm wide (small but not tiny) screwdriver, unscrew the collar that holds the diffuser. Rattle or tap the carburetor to get it to fall out the bottom.

10. (Slide fit diffuser types) Push the diffuser from the top end downward. It might drop out. If the diffuser cannot be easily removed, lightly tap on the top end with a small hammer and punch. Clear the diffuser with a high pressure air line. Use an ordinary bread wrap twist tie, to “poke out” the two idle holes in the diffuser. Use a bigger wire (paper clip?) to scrape the center hole. Carefully (wear goggles) use carb spray to both check and clean the holes. 

Note: Some carburetors are not equipped with a diffuser holder (collar). These carburetors do not have a removable diffuser. Do not try to remove the diffuser from this type of carburetor. Simply leave it installed and clear it with an air stream. See below “Press Fit Diffuser Type”.

11. Clean the fuel filter, the filter bowl, and the carburetor float bowl (fig 4). Clean the bottom guide hole by twisting a small drill bit with your fingers, to lift out the rust powder at the bottom. If this hole is dirty the float will not go down far enough, and the engine will starve at times. 

12. Unscrew the plug screw (small phillips head screwdriver) and if necessary, clean it with an air stream (fig 5). This screw gives you access to the idle circuit. Here carb spray can again, carefully (wear goggles) be used to both clean and check the idle holes and tunnels. Locate all of the holes entries and exits. Verify that spray can get through everywhere.

This last operation can be done without removing the carburetor. Turn off the gas valve, lay the bike over on it’s side, and access the idle circuit cleaning plug from the bottom. Give it a shot of carb spray, replace the plug, stand the bike up, and start the flooded engine full throttle, carefully with the rear wheel held safely above the ground by a good centerstand. After it runs fast for a minute and it gets un-flooded, hope that it idles after that.

13. Reinstall the plug screw.

Assembling the Carburetor:

1. Fit the diffuser making sure the diffuser flattened side coincides with the flat side in the carburetor hole. The slot in the diffuser lower end is for rotating it gently during installation until the flat sides line up and it snaps up into it’s “home” position, where the shoulder is just below the floor of the venturi.

2. Locate the diffuser fully home.

3. Fit the diffuser holder (6mm slot head screwdriver) and the jet (8mm wrench).

Understanding where all the holes are, where they go, and what they do, and what happens when each one gets blocked or partially blocked, is half the battle. The other half is the actual cleaning and restoring. 

True restoration is more difficult, but more rewarding than “replacement restoration”. It’s like fishing versus buying fish in the market.


Testing for Fuel Flow:

The carburetor is assembled and installed, fuel line connected, but with the jet removed. When the fuel petcock is turned on, in a few seconds fuel should begin dripping rapidly from the bottom jet hole. There should be a small continuous stream of fuel, not just rapid drips. The amount of fuel flow, for any size float-type carburetor, is enough to fill the volume of the float bowl in a few seconds. For a moped carburetor, this is about two or three teaspoons in five seconds, roughly. This tests the entire fuel system for flow. If there is low flow, then further tests are needed to isolate where it is blocked at.

Note that this is not the fuel flow to the engine. This is testing fuel flow to the reservoir or float bowl/chamber. When fuel flow to the engine, through the jet and diffuser, is blocked, the engine will not ever run right. When the jet gets partially blocked, applying the choke or blocking off some air with your hand will help compensate. When fuel flow to the reservoir is blocked, the engine will run perfect, for awhile, until the reservoir gets low. Then it will run dry and die out. Then after waiting for the float chamber to refill, the engine will restart and run fine again, for awhile, again and again.


Additional Information:

Motobecane 20mph carb sliced in half

Slide Fit and Press Fit Diffusers: Some Motobecane carburetors have “press fit” diffusers, instead of the usual “slide fit”. This is one of those types (AR2-10-737 or AR2-10-991 or perhaps others) that has been sliced in half to expose it’s secrets.

While “slide fit” diffusers slide in and out from the bottom, this “press fit” diffuser 52560, and carburetor type, slides (presses actually) in or out from the top. Many of these get smashed on top by Motobecane mechanics trying to push the diffuser downwards, the normal way out.

Press-fit-diffuser carburetors cannot be made to accept slide fit diffusers. 

Motobecane Choke Circuit cut away

Choke (cold starting) system: Unlike the Peugeot Gurtner and most other moped carburetor chokes, the Motobecane Gurtner AR2 has an additional fuel path or tunnel. It’s “choke” is a fuel enrichment device rather than an air restricting device. The choke circuit is completely independent of the main fuel circuit. It has it’s own fuel tunnel out of the float bowl, that bypasses the throttle slide, diffuser, and jet. 

Original Equipment Carbs have Dates: This carburetor clearly shows it’s manufacture date of 5/77, below the model number. It could be from a late 1977 or a 1978 bike. The 39 used Gurtner AR2 carburetors in Myrons Mopeds inventory on Dec 2014 have dates ranging from 03/74 to 04/80. The majority are from 1977 and 1979. See above “Population Study of Gurtner AR1 and AR2 Carburetors in Southern California”.   

 

 
 
Choke Slide: This is often mysteriously missing, but actually stuck in the lowest (normal) position, either by tar or corrosion. It can be unfroze with solvent and/or by removing the cable wire and pushing it up from the bottom by tapping with a small punch and hammer. When the choke slide is pulled up, the choke is “on” for cold starting, and an extra fuel path is exposed by the step in the choke slide. If the choke slide is actually missing, the choke would be “on” all the time, but some extra air gets in along with the extra fuel. So the net effect of running without a choke slide is minor.

1. CEV 9350 Tail Lights

CEV 9350: Many 1972 -1976 US mopeds, and some Italian scooters and motorcycles, had this “oval with flat sides” single bulb lamp. It meets 1972 US DOT requirements of having a brake light and shining to the sides. Original USA 9350 versions also had red lenses with side reflectors. Rear red side reflectors were required, but they did not have to be part of the light.

Sim 78 looks good in photos but it has several issues.
1. It does not have the wire connectors.
2. The connectors have to be bent and placed just right, to clear the back wall.
3. The act of adding and bending the connectors loosens the rivets.
4. The center rivet may need a thin tiny washer slid under it, to make it solid.
5. The lower tail light bulb is a special kind, a festoon. There are no 6 volt versions that can fit. There is only a 12V 5w 11 x 39mm. So on a 6 volt moped the running light will be only about half as bright.
6. The upper brake light bulb fits tight, almost to the point of the bulb breaking when removing or installing.
7. The ground wire inside eyelet gets bent when the mount screw is tightened. It is relocated to the outside.

4. CEV 9400-9417 Tail Lights

CEV 9400 and 9401 rectangular shaped rear lamps came out in 1977 on Italian mopeds. 9400 has two single filament bulbs. 9401 has one double filament bulb with a larger glass. 9401 had problems and was replaced by 9400 in 1978-79.

CEV 9417 rectangular shaped rear lamps came out in 1978 on Puch mopeds. They are mounted higher on the fender, so the mount surface is at a different angle. If a 9417 replaces a 9400 or 9401, it angles downward. To correct this new holes can be made higher up on the fender. The old holes can be hidden by the license plate mounted below the light.

 


1. 9400 and 9401 are solid mount, M6 stud and a plastic post.
1. 9417 is either solid or flexible mount, M6 stud and M6 bolt.
2. Left 9417, and right 9401 on Tomos

 

CEV 9400, 9401, 9417: The top brake light bulb is a low wattage type with a small glass 6V 10w. The bottom tail light bulb is 6V 5w. There is no ignition ground resistor.

CEV 9400.1, 9401.1, 9417.1: These are the same except for the bulb holder and upper bulb. The bulb holder is made for a “large glass” brake light bulb. This can be for a brighter brake light on battery powered motorcycles. Or it can be for many US model mopeds with a special “external ignition ground” that powers the brake light. On those the brake light bulb needs to be 6V 21W in order to have good spark with the brakes on.

If the brake light burned out, the resistor would allow the engine to stay running. In ’78-79 the 9400.2, 9401.2 and 9417.2 superseded the 9400.1, 9401.1, and 9417.1.

2. none  222639-O orange sides, 1-b. 12V 10/5w

These lamps look exactly like the original CEV 9417 on the outside. But inside the bulb holder-mirror is different. It is a single bulb type that cannot be swapped for an original 2-bulb type. In the USA, in motorcycle parts stores, the single dual filament bulb has limited choices in volts and watts. There is just 12V 21/5W #1157 or 6V 21/5W #1154. 

Because of the bulb availability, this lamp with a 6V 21/5W #1154 bulb is a good substitute for 9417.1 or 9417.2, without any resistor. But it is not a good substitute for 9417 because 6V 10/5W or 12V 10/5W dual filament bulbs are unavailable in USA auto parts stores. 

The three male blade connecters have a tiny barb on top. The barb can be depressed with a tiny screwdriver. That allows the connectors to be removed. Then the original lens and/or bulb holder can be transferred onto it. But modification is required. More to follow…

This lamp also looks exactly like the original CEV 9417. Inside it has a 2 bulb holder-mirror. The bulbs can be 6 or 12 volt, and 5 or 10 watt. A 1970’s bike needs 6V, but a 1990’s or later needs 12 volt bulbs. 

This entire lamp is a good substitute for CEV 9417.

Many 1970’s US-model bikes had a “secret” ignition ground resistor hidden inside this light. It allowed the bike to run even when the brake light was missing or burned out. This new light cannot hold a resistor, but one can be added to the ignition ground wire above the engine. The resistor is listed below.

Jules Gurtner started making carburetors in 1907, for some of the earliest automobiles and motorcycles.

Gurtner carburetors are made in France, and original on French mopeds Peugeot and Motobecane. See also mopedarmy.com

Gurtner Master Catalogs: Here are the 1961 Gurtner Catalog and the 1980 Gurtner Catalog from motobec.fr. 

Gurtner Moped Carburetors: Here are the 1961 Carb List and the 1980 Carb List. From those you can see that about one third of all Gurtner carbs are for mopeds (mobylettes). Before 1960, most Mobylettes had 10mm carburetors (or 8.7). So the speed and power were limited to be under about 25mph. After 1959, some had 10mm carbs and went 25mph, and some had 13mm carbs and went 30-35mph.

Much of this information and photos are from the Motobecane Club of France.

Gurtner AR2 series moped carburetors have a large flange, like a wall. It is for an “air box”, a noise silencing, fuel mist recovering, and air filtering chamber. There are two (venturi) sizes, 10 or 12 mm, and two styles, side or center mount. Center and side mount carbs look the same, but don’t interchange completely.

3B.  AR2 Information

Side mount carburetors have threads for an air filter stud, side holes for a center mount air box clip, and clamp to a 19mm intake pipe. The side mount float top cover has a vertical fuel hose spigot. A stripped bare side mount body, as is, will exactly replace a bare center mount body.

Center mount carburetors have no threads in the stud hole, side holes for a center mount air box clip, and have removable sleeves, black 16 x 19 (for AR210), and white 17 x 19mm (for AR212). The sleeves reduce the precision clamp size from 19mm to 16 or 17. The purpose is to be tamper resistant. The sleeves fit tight and are difficult to remove without damaging them. The center mount float top cover has a horizontal fuel hose spigot. A stripped bare center mount body, after threads are cut in the air box post hole, will replace a bare side mount body.

Center mount early  Some pre-USA years 1960’s or early 1970’s had no fuel hose inlet in the float top cover. Instead it was in the carburetor body just below the float top. This type is in many Motobecane USA parts illustrations, but it was not used on any, or hardly any US models. In the illustration below it was edited out. Out of 47 original carbs, taken off once-living Motobecanes from around Southern California, none were this “center mount early” type with the fuel hose spigot in the carb body.

is pre-1978 12mm, 5mm stud, thin mount.

13512 is 1978-on 12mm, 6mm stud, thick mount.
13510 is 1978-on 10mm, 6mm stud, thick mount.

In 1977 the air box stud 5 mm threads would sometimes get stripped, or the clamp mounts would sometimes break. So during 1978, on some they made the air box stud 6 mm and the casting thicker at the mount. From 1979-on all were 6 mm.

Mount Type: All Motobecane carbs clamp to 19.0mm inlet pipes. But many of the pre-March 1978 carburetors were cracking at the edge of the clamp, or the base of the petals. So Gurtner beefed up the carb body with a reinforcing ring, made the clamp petals about 1mm thicker each, and changed the clamp to the bigger Peugeot double-wall type.

Air Filter Stud: When the mount was made stronger in 1978, the air filter post was also beefed up from 5mm to 6mm. This made the threads in the body more resistant to stripping. Another issue that was improved is when the air filter stud is over tightened, a bulge can form in the float chamber wall behind it. That bulge makes the float stick. See below.

Center Mount Air Cover: The center mount type (short and deep) air box is too deep and sticks out too much as a side mount. The right side engine cover panel must be removed, and some kind of high-offset right pedal crank arm installed. Then maybe pedal threads are different.

Side Mount Air Cover: The side mount type (tall and flat) air box is too tall and hits the frame as a center mount. More importantly, they break, fall off, and get thrown away, in addition to getting lost. Because of that, they have become scarce and pricey. From 2000-2015 maybe 200 people have asked for this item, but only two were available and sold at MM.

Motobecane side mount air box nut and cupped washer upgrade

Side mount air cover breaks without cupped washer/nut.

The Motobecane piston-port two-stroke engine needs the air cover because the gasoline mist flows in and out in both directions. So there is a little cloud of fuel and oil mist out in front of the carburetor. Without the air cover, this fuel cloud gets wasted and blown away (or ends up on the riders right leg or shoe). Besides that, the air cover provides the correct amount of flow restriction, which is a good thing, up to a point. See below about running without an air cover (how it can damage the engine by over-heating from not enough fuel and oil).

 

 

Air cover substitution: Here is a center-mount air cover installed on a side-mount carburetor. Holes have to be drilled for the mounting wire clip, and the lower right corner has to be warmed up and molded inward where it touches the round magneto base plate. More importantly, the side cover must be removed, and it almost touches the pedal. So it’s easy to kick it when pedalling.

Choke Slide: This is often mysteriously missing, but actually stuck in the lowest (normal) position, either by tar or corrosion. It can be unfroze with solvent and/or by removing the cable wire and pushing it up from the bottom by tapping with a small punch and hammer. When the choke slide is pulled up, the choke is “on” for cold starting, and an extra fuel path is exposed by the step in the choke slide. If the choke slide is actually missing, the choke would be “on” all the time, but some extra air gets in along with the extra fuel. So the net effect of running without a choke slide is minor. 

Top Pull or Bottom Pull Choke Cable:

1. On center mount carburetors, for variator models, the choke cable is “top pull”. The choke and throttle cables detach, allowing the carburetor to be serviced away from the bike.

Gurtner AR2 top pull choke cable routing

2. On side mount carbs for non-variator (Dimoby) models, the choke cable is “top pull”, but has a elbow (curved tube), like the throttle cable. The choke and throttle cables detach, allowing the carburetor to be serviced away from the bike.

Gurtner MB bottom pull choke parts exposed

AR2 bottom pull choke parts exposed

3. On side mount carbs for ’78-later 30mph variator models, the choke cable is “bottom pull”, where the choke wire runs through the carb body, trapping it on or near the bike. On those most service operations are done with cables attached, about one foot away from the bike. To remove the carb you have to pull the choke wire all the way out. Then it won’t usually go back because the braided end gets frayed. Then the choke wire has to be replaced. 

 

 Le Diffuseur: When you look down the “throat” or venturi of a Gurtner carburetor, with the throttle wide open (throttle slide up and out of the way of the air), the little brass tube that sticks up from the floor of the venturi is the diffuser. It sprays the gasoline mist sucked up by the moving air.

Left, top are the way more common type, the “slide fit” type diffusers. Can you see, besides the main large hole down the middle, that each diffuser has two small holes facing out of the page? Those are the idle holes. When they are blocked, the engine will run OK, but will not run slow or “idle”. On a 21002 diffuser the idle holes are 0.016″. That size hole is cleaned with a #78 drill, also 0.016″.

Left, bottom are the less common type, the “press fit” type diffusers. You can only see one idle hole on this kind, but there is another on the opposite side. These diffusers have a very small center hole, that serves has the limiting jet. They are installed by pressing in from above, instead of sliding in from below like the other kind. The purpose of this type is to be tamper resistant. There is no particular direction that they have to be aimed at, and no flat side in the carb body for that purpose.

 

Motobecane 20mph carb sliced in half

Slide Fit and Press Fit Diffusers: Some Motobecane carburetors have “press fit” diffusers, instead of the usual “slide fit”. This is one of those types (AR2-10-737 or AR2-10-991 or perhaps others) that has been sliced in half to expose it’s secrets.

While “slide fit” diffusers slide in and out from the bottom, this “press fit” diffuser 52560, and carburetor type, slides (presses actually) in or out from the top. Many of these get smashed on top by Motobecane mechanics trying to push the diffuser downwards, the normal way out.

Press-fit-diffuser carburetors cannot be made to accept slide fit diffusers. 

 

Motobecane Choke Circuit cut away

Choke (cold starting) system: Unlike the Peugeot Gurtner and most other moped carburetor chokes, the Motobecane Gurtner AR2 has an additional fuel path or tunnel. It’s “choke” is a fuel enrichment device rather than an air restricting device. The choke circuit is completely independent of the main fuel circuit. It has it’s own fuel tunnel out of the float bowl, that bypasses the throttle slide, diffuser, and jet. 

Original Equipment Carbs have Dates: This carburetor clearly shows it’s manufacture date of 5/77, below the model number. It could be from a late 1977 or a 1978 bike. The 39 used Gurtner AR2 carburetors in Myrons Mopeds inventory on Dec 2014 have dates ranging from 03/74 to 04/80. The majority are from 1977 and 1979. See above “Population Study of Gurtner AR1 and AR2 Carburetors in Southern California”.

Gurtner Floats

Gurtner 6437 and 4901

On 1970’s US mopeds there are 3 Gurtner floats:
5186 (Motobecane 14123) for AR1 carbs on Model 7

4901 (Motobecane 14101) for AR2 carbs on 40, 50
6437 (Peugeot 06437) for D-type carbs on 102, 103

Gurtner used to color code their new float containers green for Motobecane and red for Peugeot. Otherwise they are almost indistinguishable, unless together side by side. 

5186, 4901, 6437 specs

6685 specs

Float Service: On plastic types the needle is a press fit into the top and bottom holes in the bulb. The needle can simply need moving up or down. Or it could also need the tip straightened and/or sharpened/machined. Or the needle could need to be replaced, if it has become too short or too bent. Any piece of 1.5mm brass rod, cut to these lengths, and machined to a cone tip, would restore the float. In addition, a gasoline-proof sealant should be used to seal the press-fit holes, as a precaution, or if gasoline enters the bulb.

8. Jets

 

 

There are three types of Gurtner jets (gicleurs), 581, 5012, and 9831. 

5012

M5.5-0.75 thread

 

 

581

M7-1.0 thread

 

 

9831

M7-1.0 thread

 

 

 

There are three size label types, here called 60’s, 70’s and 80’s.
A  581  jet, 60’s size 21, equals 70’s size 215, equals 80’s size 53.
A 5012 jet, 60’s size 21, equals 70’s size 215, equals 80’s size 54.
A 9831 jet, 60’s size 00, equals 70’s size 215, equals 80’s size 55.

Use this table to cross reference Gurtner sizes.

Population Study of Gurtner AR1 and AR2 Carburetors in Southern California

These 47 Motobecane carburetors all came from whole bikes that were stripped out for parts. The Motobecane population in the greater Los Angeles area is roughly represented by this large subset. Out of 47 carbs there were only two AR1 types, from Model 7. All of the 45 others were from Models 40 and 50.

total  47

These are the surviving Motobecane carburetors that lasted longer than the rest of the bike. If there were times when the metal was weak, those months or batches would be missing from this collection, pretty much, because the ones that tended to break already broke and were thrown away. It seems like 1978 is missing some survivors, mysteriously. Perhaps they were used as upgrades/replacements for 1976-77 thin-mount ones that broke. You can see from this sub-population that early carburetors were center mount, and late ones were side mount, and in between was both.

clip ∅14 x 1.2,  1 tail   $1.50  generic 633848

Choices: 1 or 2 tails is easier to install or remove. No tail is better for high RPM, where the tail rubs and can break off. No tail clips require a notch in the piston for removal. Circlip type (aka snap ring or retaining ring) is more secure and takes less skill, but requires special pliers and weighs more.

Important: So the clip doesn’t come out and destroy the engine, it must make a “snap” or “click” sound when it snaps into the groove. Mild pulling on the clip tail with a needle-nose pliers should not dislodge it from the clip groove. If it doesn’t click, then it has lost it’s spring tension, or maybe the piston pin is over part of the clip groove. Wire clips can be bent back, to restore tension.

Circlips are circular clips. Officially they are known as retaining rings. The “size” is not the actual size, but rather the size of the shaft or hole that it is for. For external rings, the shaft size “For OD” is more than the groove OD, which is more than the actual ring ID. For internal rings, the hole size “For ID” is less than the groove ID, which is less than the actual ring OD.

There is a “click” sound when the spring-loaded clip-ring snaps into the clip-ring groove. The ring should be free to rotate, but with some friction from the spring tension. If the ring is too big it will rotate with no friction. If the ring is too small it will have to be over-stretched to get on, and will rotate with much friction. That’s how to tell if a clip-ring fits properly, by feeling, hearing and seeing.

7 – 9 x 0.7  $2 for 6.0 groove, Derbi #00.473.08, clutch shoes

While the other clips are named by the shaft size, these E-clips are often named by the groove size. Since they install from the side they don’t have to spread over the shaft. So the shaft size does not matter. Puch calls the “7-9 x 0.7” e-clip “BZ-circlip 6”. The groove is 6.0mm but the shaft is 7.6mm.

Laura, Motobecane, Batavus, Badger, Solo, Angel, Speed Bird magneto covers all interchange, because they all have a 124 mm inner diameter. Here are some original examples:

1980’s Motobecane engine cover
124mm ID, black, with tabs, price $19.0

Above, this one cover fits and replaces all of those covers above. It is exactly for a early 1980’s Motobecane. But it fits anything that takes a 124mm ID round cover.  It is deep enough for stock mopeds. But it is not deep enough for some Motobecane CDI magnetos, or any that are much taller than stock. It comes with two rubber clips to hold it onto the metal “ears” on the engine case.


Motobecane

Motobecane side covers are listed in Motobecane 40, 50, 50V Parts, section 28-29 frame parts.

 

Motobecane 50 Leg Shields

   
This is an original leg shield set #20250, and mounting bracket set #20290.
It is new but there are some minor scratches, from years of being kept on parts shelves.
These have all sold. Only the lower mount kit is available.

Here is a diagram of some 1950-60’s Motobecane leg shields. The mounts are different.

Battery Boxes and Covers

Battery boxes were on early 70’s Ciao (US models with brake light), and late 70’s to early 80’s Ciao, Bravo, and Grande “blinker” models (equipped with turn signals and different switches and equipment). These side box covers have been scarce since the late 1980’s. They often fall off, and nobody is reproducing them. If you know of a source please tell Shaun by email.

The larger size box 227 x 160 mm is on Grande. Price $10 per box without lid, good-used.

The smaller box 222 x 158 mm is on Ciao and Bravo. $12 per box without lid, good-used.

Vespa battery boxes and covers have two sizes.
A large cover will fit a small box, but not visa versa.

Belts

October 24, 2015

 


1. Cogged Belts

These are also called timing belts and synchronous belts, because like a chain, they cannot slip. There are not many mopeds or mini-cycles with cogged (toothed) belts.

Besides different lengths and widths there are also different pitches and profiles (tooth shapes). So there are thousands of possible cogged belts. The belt length is the tooth count times the pitch. So a 610-5M belt has 610/5 = 122 teeth.

type T10 profile
10mm trapezoidal

type T5 profile
5mm trapezoidal

type S5M profile
5mm high torque

type 5M profile
5mm rounded teeth

 

 

 

 

 

 

 

610-5M-18

Di Blasi: The 1997-on DiBlasi R7E has a cogged drive belt 18mm wide, and has 122 teeth that repeat every 5mm (5mm pitch). 122 x 5 = 610 mm length. One replacement that is shorter is 600-5M-18, with 120 teeth. It fits and meshes correctly, but only when the adjustment slots are lengthened. A 610-5M-18 with 122 teeth is the original size.

Here is a 610-5M-18 in New Jersey.

 

 

T5x395-20 (395-T5-20)

 

Laura M56: This engine from Holland is on 1978-80 Batavus and 1982-85 Trac mopeds. The original belt was 20mm wide, had 79 teeth with 5mm pitch. 79 x 5 = 395 mm length. The tooth profile was T5, not 5M. Very similar belts 400-5M-20 and 395-5M-20 do not mesh right.

T5x395-20, price none 

 

T5x390-20 (390-T5-20)

Laura M56 with shaved teeth: For many years, there was only a shorter belt available. 78 x 5 = 390 length. It required shaving down the tooth tops of the big pulley. 100’s of bikes had that done. Those bikes would still need a one-tooth-less belt.

T5x390-20, price none

V-Belts Explained

The smooth sides of V-belts are what grips the pulley. The harder the pull, the more it grips, because of the V angle. The top and bottom do not touch anything. 

Moped V-Belts

First is a graphic showing the cross-sectional shapes and sizes of replacement V-belts that can be used on mopeds and small scooters. V-belts for variators (variable pulleys) are the “low profile” type, called “variable speed belts”. V-belts for fixed pulleys are the “high profile” type, called either “classic” or “cogged”, see below.  

V-belts are made by Gates in different styles, widths, and lengths. Here the width choices from 9.5 to 17.5 mm. Larger or smaller sizes are omitted. 

9.5 mm  3L, 3V, 3VX
10.0 mm 10X, SPZ, XPZ
11.9 mm automotive 15
12.7 mm 4L, A, AX
13.0 mm 13X, SPA, XPA
13.5 mm automotive 17
15.9 mm 5V, 5VX
16.0 mm SPB, XPB
16.7 mm 5L, B, BX

17.0 mm 17X
17.5 mm automotive 22

Smooth or Notched: The notches, or cogs, on V-belts are not teeth, like on toothed belts. They are relief slots that help the belt bend easier, for less friction and more efficiency. Equipment that originally had smooth belts can use cogged belts, and visa versa.

History of L.A. to Anaheim Roads

September 2, 2015

El Camino Real bell

As you drive the same streets everyday, you know your local streets by name, and where they go to. But did you ever wonder how the streets in your local area came to be the way they are?

The author, Shaun Strahm did, in his local area of Fullerton California. He wanted to know 1) where all the streets came from, and 2) where the “real” El Camino Real went. That is what this blog is about.

Introduction

There are several different possible routes through the coverage area, north Orange County and southeast Los Angeles County, for the early mission road. There are also many places that claim to be on the El Camino Real. Since the early 1900’s the romance of the Spanish missions and trails have been used to attract visitors to places or customers to products. There are many historic maps that approximate the route. At right is one, that uses the nearest automobile road of the day, to make a glamorous automobile tour. In general, the actual trail never went due north or due west. It was always at some angle, generally northwest.  

In order to understand the places names on early maps, much other information had to be gathered, especially names of places and land owners, families, and dates. Old adobe home sites are called by different names on different maps, depending on who owned them at the time. The early Spanish maps were distorted because they did not use observation balloons, instead they paced off distances and measured angles. So several historic maps had to be combined to reduce omissions or distortions. 

 

 

Here is the history of the Los Angeles to Anaheim area, relating to the layout of the land. 

History of the Land

The Tongva people were here first.

The Tongva people lived in reed huts.

Native People Period

Southern California is believed to have been inhabited by semi-nomadic hunters since 8000 BC. Three thousand years later in 5000 BC, seed and shellfish gatherers lived among large game hunters in this region. By 800 AD, the people of this region had developed a diversified hunting and gathering economy with extensive trade networks, social and political structures, and religious institutions. The descendants of these people are believed to have been those whom the Spaniards of the 1500s encountered and would later name the Gabrielino—derived from Mission San Gabriel—in the late 1700s. See below, the 1860 Map of Los Angeles County that shows dozens of Indian settlements/campsites. Many Indian settlement names became modern city or place names, like Cahuenga, Cucamonga, Topanga, Temescal, Tujunga.

 

Actual Camino Real in Baja

Actual Camino Real in Baja

Spanish Period 1697-1821

Starting in the 1500’s, Spanish ships sailed along the coast of the South and North America, looking for harbors and a short cut back to Europe. From their ships, they made maps and named all of the coastal places after religious figures. Most of the San and Santa place names were established in the 1600’s, as Spain was planning it’s colonization of the Americas.

The first Europeans to walk on California land was the Portola Expedition in 1769, led by Gaspar de Portolá, to look for the best routes and places for missions and settlements. They charted and named the rivers, mountains, and places along the way. The first European settlements in Orange County and southern Los Angeles County were Mission San Gabriel in 1771, Mission San Juan Capistrano in 1776, El Pueblo de Los Angeles in 1781, Rancho Los Nietos in 1795, Santa Ana Viejo (Olive) in 1812, and the Diego Sepúlveda Estancia in 1823.

 

Old Mission San Gabriel site

Old Mission San Gabriel site in Montebello

Mission San Gabriel Arcángel

From Wikipedia: Mission San Gabriel was founded on September 8, 1771 by Father Junipero Serra. The planned site for the Mission was along the banks of the Río de los Temblores (the River of the Earthquakes—the Santa Ana River). The priests chose an alternate site on a fertile plain located directly alongside the Rio Hondo in the Whittier Narrows. The site of the Misión Vieja (or “Old Mission”) is located near the intersection of San Gabriel Boulevard and Lincoln Avenue in Montebello, California (known to the natives as Shevaanga). In 1776, a flash flood destroyed much of the crops and ruined the Mission complex, which was subsequently relocated five miles closer to the mountains in present-day San Gabriel (the native settlement of ‘Iisanchanga). The Mission is the base from which the pueblo that became the city of Los Angeles was sent.

Legend has it that the founding expedition was confronted by a large group of native Tongva peoples whose intention was to drive the strangers away. One of the padres laid a painting of “Our Lady of Sorrows” on the ground for all to see, whereupon the natives, designated by the settlers as the Gabrieliños, immediately made peace with the missionaries, because they were so moved by the painting’s beauty. Today the 300-year-old work hangs in the Mission’s sanctuary.

 

Spanish Ranchos

1834 Diseño de los parages llamados

1834 Diseño de los parages llamados (design of the places called) Santa Gertrudes, Coyotes, Bolsas, Alamitos y Sierritos

In 1802, Spanish governor José Joaquín de Arrillaga gave to Juan Pablo Grijalva, a Spanish soldier who was with the De Anza expedition, permission to use the 63,414-acre land known as Rancho Santiago de Santa Ana. Upon Grijalva’s death in 1806, the land passed to his son-in-law, Jose Antonio Yorba and his grandson, Juan Pablo Peralta.

In 1784, Spanish governor Pedro Fages gave to Manuel Nieto, a former sergeant in the Spanish army, and a member of the Portola expedition in 1769, permission to use all of the 167,000 acres of land known as Rancho Los Nietos, between the Santa Ana River and the San Gabriel River, and from present day Whittier to the Pacific Ocean. Neito built an adobe home in 1795 near the Indian village of Sejat, on the San Jose Creek. Upon Manual Neito’s death in 1804, the land passed onto his wife and four children. The flood of 1867-68 destroyed the original home.  

The Nieto family operated the cattle ranch until 1834, when Mexican Governer Jose Figueroa officially declared the Rancho Los Nietos land under Mexican rule and ordered its partition into six smaller ranchos. The partitioning of Rancho Los Neitos was done as follows:
Los Alamitos (little poplars), 28,612 acres, to (son) Juan Jose Nieto
Las Bolsas (pockets), 33,460 acres, to Catarina Ruiz (widow of (son) Jose Antonio Nieto)
Los Cerritos (little hills), 27,054 acres, to (daughter) Maria Manuela Nieto de Cota and her husband Guillermo Cota
Los Coyotes (coyotes), 48,806 acres, to (son) Juan Jose Nieto
Santa Gertrudes, 21,298 acres, to Josefa Cota (widow of (son) Antonio Maria Nieto)
Palos Altos (tall woods), not illustrated, unknown acres, to (son) Juan Jose Nieto

 

1823 Carta esferica de Alta California

1823 Carta esferica de Alta California

Mexican Period 1821-1846

The first ranchos of Los Angeles and Orange Counties are on the 1823 Carta at right, Berdugo, Bernardino, Flores, Gutierrez, Nieto, Yorba, as well as the missions and pueblos. 

There were not many maps made in the Spanish and Mexican periods. The Spanish land surveyors used natural landmarks like rivers, trees, rocky outcrops, or distant mountain peaks as corner points for their property lines. One prominent rocky outcrop is Red Hill, in what is now Tustin. It is the corner of Rancho Santiago de Santa Ana, Rancho San Joaquin, and Rancho Lomas de Santiago. A nearby plaque at 11911 Red Hill Ave commemorates the landmark. 

Red Hill 

Red Hill was identified on Spanish maps as Serrita de las Ranas (translation: Hill of the Frogs). The original route for El Camino Real ran close to the hill. The landmark peak was used by the Spanish and Mexican explorers traveling up and down the coast. The nearby frogs thrived because of a swampy bog that connected the hill and the back bay in Newport Beach. The bog disappeared with the development of the city of Tustin. The red color results from the mineral cinnabar (mercuric sulfide, HgS, the major source of mercury). Mercury was mined there up into the 1930s. The mines are closed off and the appearance of the hill is preserved as a California historical landmark.

 

Coyote ranch house

Rancho Los Coyotes headquarters in 1900

Rancho Los Coyotes

In 1840, Juan Jose Nieto sold Rancho Los Coyotes to Juan Bautista Leandry, an Italian immigrant who settled in California in 1827, and was married to Maria Francisca Uribe. They built an adobe house on the hill, in what is now Buena Park, near the south end of Lockhaven Drive. Leandry died in 1842, and his widow, Maria Francisca Uribe, married Francisco O’Campo. Uribe renamed the ranch “La Buena Esperanza” (the good hope) but it was still generally known as Los Coyotes. Rancho Los Coyotes would later become the cities of Buena Park, Cerritos, Cypress, La Mirada, and Stanton

 

Rancho Santa Gertrudes

Rancho Santa Gertrudes was a 21,298-acre 1834 Mexican land grant, resulting from a partition of Rancho Los Nietos. It included the former Tongva site known as Nacaugna.  

From Wikipedia: At the request of Manuel Nieto heirs, governor José Figueroa in 1834, officially declared the 167,000-acre Rancho Los Nietos grant under Mexican rule and ordered its partition into five smaller ranchos: Las Bolsas, Los Alamitos, Los Cerritos, Los Coyotes, and Santa Gertrudes. Josefa Cota (widow of Antonio Maria Nieto, son of Manuel Nieto) received the Rancho Santa Gertrudes grant. Lemuel Carpenter (1808–1859), who had married Maria de Los Angeles Dominguez, a niece of Josefa Cota, bought the rancho in 1843 from Josefa Cota, his aunt by marriage.

With the cession of California to the United States following the Mexican-American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored. As required by the Land Act of 1851, a claim for part of Rancho Santa Gertrudes was filed Lemuel Carpenter in 1852. Carpenter, who was deeply in debt to John G. Downey, killed himself in 1859. In 1859 the rancho was sold at a sheriff’s auction to John G. Downey and James P. McFarland. 17,602 acres of the grant was patented to McFarland and Downey in 1870. A claim for part of Rancho Santa Gertrudes was filed by Thomas Sanchez Colima with the Public Land Commission in 1852, and 3,696 acres of the grant was patented to Thomas Sanchez Colima in 1877. Rancho Santa Gertrudes would later become the present-day cities of Downey and Santa Fe Springs.

Rancho San Juan Cajón de Santa Ana

East of Rancho Los Coyotes was 35,971 acres of land, granted to Juan Pacifico Ontiveros in 1837, by Mexican Governor Juan B. Alvarado. Ontiveros built an adobe house in 1841, in what is now Placentia, on Crowther Ave and Porter Way. In 1853, Ontiveros sold 21,527 acres to Abel Stearns. In 1855, Ontiveros bought a rancho in present-day northern Santa Barbara County, then built an adobe house and lived there until his death.

In 1857, Ontiveros sold 1,160 acres that would become Anaheim, to George Hansen who was working for 50 German-American families from the San Francisco area. In 1863, Juan Pacifico Ontiveros gave his sons Juan Nicolas Ontiveros and Patricio Ontiveros 3,900 acres of Rancho San Juan Cajón de Santa Ana. At this time, they were both married. Juan Nicolas and Patricio did not keep their share very long, and in 1864, both deeded their share to their brother-in-law, Augustus Langenberger (married Pietra Ontiveros).

In 1865, Daniel Kraemer started the influx of settlers to Placentia in 1865, when he purchased 3,900 acres. Rancho San Juan Cahon de Santa Ana would later become the cities of Anaheim, Brea, Fullerton, and Placentia

 

 

Rancho Santiago de Santa Ana

Old Santa Ana Historical Lamdmark

Historical Lamdmark

Juan Pablo Grijalva, a Spanish soldier who traveled to Alta California with the De Anza expedition, was the original petitioner for the 63,414-acre land that became known as the “Rancho Santiago de Santa Ana”, formerly “Rancho Lomas de Santiago”. He died in 1806 before the grant was approved and in 1810 the land went to his son-in-law, Jose Antonio Yorba and his grandson, Juan Pablo Peralta

Juan Pablo Grijalva built an adobe, in about 1801, one of the first in Orange County, at what is now 1087 N Santiago Blvd in Orange. A few years later and a mile north of there, where the Santa Ana River bends around the Peralta Hills, Juan Pablo Peralta and Jose Antonio Yorba built small adobe homes. Those early adobes were ruins by 1860. A plaque commemorates the site, that was first called “Santa Ana” but later “Old Santa Ana” after the city of Santa Ana was formed in 1869 several miles south. It is also the place where the original Camino Real crossed the Santa Ana River. Jose Antonio Yorba built an elaborate adobe hacienda, El Refugio (the Refuge), located near present-day First and Sullivan Streets in Santa Ana.

After the Mexican Cession of California to the United States, grant was patented to Bernardo, Teodoro and Ramón Yorba in 1853 by Mexican governer Jose Figueroa. Bernardo Yorba built his famous “Hacienda de San Antonio” on the north bank of the Santa Ana River, at what is now Esperanza Rd and Echo Hill Ln in Yorba Linda. The spacious two-story adobe had living quarters, guest rooms, and space for craftsmen, laborers and servants. Ramon Peralta built an adobe at what is now 6398 E Santa Ana Canyon Rd, That is the only adobe in the Santa Ana Canyon still standing today. It has a small museum featuring artifacts excavated at the site, and timeline mural, and other exhibits. In 1854, the Yorba family sold Rancho Santiago de Santa Ana to José Antonio Andrés Sepúlveda. Sepúlveda later lost the land due to bankruptcy caused by fighting to uphold his land claims in court. In 1869, William Spurgeon and Ward Bradford purchased 74.27 acres of the ranch to form the city of Santa Ana. Santa Ana became the county seat of government when Orange County was formed in 1889. Rancho Santiago de Santa Ana would later become Santa Ana. Orange, Villa Park, Anaheim Hills, El Modena, Tustin, Costa Mesa, and a part of Irvine.

Rancho Paso de Bartolo

From Wikipedia: Rancho Paso de Bartolo was given in 1835 by Governor Jose Figueroa to Juan Crispin Perez. The name refers to a San Gabriel River ford called Paso de Bartolo Viejo (Old Bartolo’s Crossing). 

Initially property of the San Gabriel Mission, the Rancho Paso de Bartolo land became a part of the original 300,000-acre Rancho Los Nietos grant. After an appeal by the mission padres, Rancho Los Nietos was later reduced to 167,000-acre, and Rancho Paso de Bartolo was once again a possession of the mission. Following secularization of the missions, Rancho Paso de Bartolo was granted in 1835 to Juan Crispin Perez, a manager at the mission.

In 1843, Bernardo Guirado, a worker at the mission, acquired 876 acres of Paso de Bartolo from Perez. Later, Joaquina Ana Sepulveda, widow of Juan de Jesus Poyorena, acquired another 208 acres. In 1847, Juan Crispin Perez died leaving the rancho to his family. After the Mexican-American war, former Governor Pío Pico began purchasing pieces of the estate from the heirs of Perez, and by 1852, he acquired 8,991 acres of the rancho. The land grant was patented with 876 acres to Bernardo Guirado in 1867, 208 acres to Joaquína Sepulveda in 1881, and 8,991 acres to Pio Pico and Juan C. Perez in 1881.

Pío Pico built a home in 1853. The home was damaged by the flooding of 1867, which set the San Gabriel River to its present course, and was nearly destroyed in 1882 by flooding. The structure was completely redone into its current form, adding American-style elements into the traditional Califorino design. In 1892, Pio Pico was evicted from the property by Bernard Cohn, an American lawyer. When taking what he thought was a loan from Cohn in 1883, Pico, who could not read or write English, had conveyed the deed for the property, and courts ruled with Cohn. Pico died a pauper two years later at his daughter’s home. Rancho Paso de Bartolo would later become the cities of Montebello, Whittier, and Pico Rivera.

 

Rancho Cañada de La Habra

From WikipediaRancho La Habra (also called “Rancho Cañada de La Habra”) was a 6,698-acre Mexican land grant given in 1839 by Governor Juan Alvarado to Mariano Reyes Roldan. The name refers to the “Pass Through the Hills”, the natural pass to the north between the Chino Hills and Puente Hills into the San Gabriel Valley, first discovered by Spanish explorers in 1769. The La Habra grant was shaped like a wedge pointed south.

California’s Mexican Governor Juan B. Alvarado awarded the land grant of 1.5 square leagues to Mariano Reyes Roldan, a 40-year-old ayuntamiento (municipal council member) of Los Angeles. Roldan named it Rancho Canada de le Habra. Roldan sold the rancho to Andrés Pico. As required by the Land Act of 1851, a claim for Rancho Paso de Bartolo was filed with the Public Land Commision in 1852. The grant was patented to Andrés Pico and Francisco de Uribe de Campo in 1872. Abel Stearns purchased the land in 1861, however, after the drought in 1863, and forced to sell. Most of the new purchasers were Basque sheep growers. Domingo Bastanchury and Jose Sansinena were partners until 1889, when Sansinena acquired a 5,000-acre sheep ranch that included most of La Habra and La Habra Heights. Jose Sansinena died in 1896.  Rancho La Habra would later become the cities of La Habra and La Habra Heights.

 

Rancho San Joaquin

1841 Sitio de San Joaquin

1841 Sitio (site) de San Joaquin (later Irvine Ranch)

This interesting color map of Rancho San Joaquin (before it was Irvine Ranch) shows approximately where El Camino Real went through Irvine. The map is tilted so that north is the upper left. The Camino Real crosses the southeast lindero (boundary) on the right. The lindero goes southwest into Cañon de Lagos (Canyon of Lakes, later called Laguna Canyon), to the playa (beach). The southwestern half of the rancho is the golden colored Lomarios de la Costa (Hills of the Coast, later called San Joaquin Hills). Along the top of the map are the Sierra de Santa Ana (Santa Ana Mountains), which form the northeast boundary. Shown are the aguajes (springs), and the mojoneros (corner points). Prominent on the lower left is the Boca de San Joaquin (later called Newport Bay). There are three successive lagoons illustrated, heading inland, which are lower and upper Newport Bay. The original casa is shown near where the University of California Irvine is now. At the left the Camino Real passes la Cienega de las Ranas (marsh of frogs) which is shaded blue. The royal road has to veer east to avoid the frog bog. That is why the El Camino Real (nuevo) does not go straight through Irvine to Santa Ana. During the wet season the marsh would extend from Upper Newport Bay almost all the way to Red Hill. 

Rancho San Joaquin became Irvine, Tustin, Santa Ana Heights, Newport Beach, Corona del Mar, Laguna Beach

This southern fragment of Rancho Los Neitos was granted to Juan Jose Nieto, son of Manuel Nieto. Where the Los Angeles River, San Gabriel River, the Rio Hondo and Coyote Creek all empty into the San Pedro Bay, are areas that flooded each year. The native Fremont cottonwood trees, also known as Alamo cottonwoods, would sprout each year in the riverbeds and grow to a few feet tall. Then the seasonal winter rains would flood the riverbeds and wash everything away. So the wide riverbeds with many small Alamo trees were given the name Los Alamitos.

Fremont Cottonwoods (Populus Fremontii) are native and very common in Southwestern USA riparian settings, where there is water below ground. In winter the leaves turn yellow, in stark contrast to surrounding golden brown or pale green trees and brush. From a distance, in winter, you can tell where water is at. Follow the ribbons of yellow to where the most Alamo cottonwoods are, then hope for an above-ground spring.

Newport Boulevard

Rancho Santiago de Santa Ana is the largest and longest rancho, shaded green on the map, that extends all of the way across the county. It’s southeast boundary, with Rancho San Joaquin and Rancho Lomas de Santiago, would later become the most important line in Orange County. The line runs perpendicular to the coastline from Newport Bay to Red Hill, and then on to a certain spot on the Santa Ana River. All of the streets in central Orange County are parallel or perpendicular to that Red Hill-to-Newport Bay boundary line. Newport Blvd is parallel to the line and about a mile north. Northwest of Newport Blvd the streets are not tilted (except Anaheim) and the cites of Anaheim, Santa Ana, Tustin, Orange were developed in the 1800’s. Southeast of Newport Blvd the streets are tilted, and the land was not developed until the 1900’s. Read how Mr. James Irvine did not want his land farmed or developed.

Anaheim

The 1857 settlement of Anaheim was situated twenty-seven miles southeast from Los Angeles on the crossroads of wagon trails between San Pedro, San Bernardino, and Salt Lake City, and on the stage road between Los Angeles and San Diego. The boundaries were:

“Commencing at a point on said rancho where there is a stake, and which stake is 9 chains and 50 links south, 70 1/2 degrees west of the western comer of a small garden belonging to said Ontiveros, and which is situate about 3 1/4 miles westerly of the house now occupied by said Ontiveros, and running thence . . . from said point north 15 1/2 degrees west 42 chains, thence south 74 1/2 degrees west 116 chains and 50 links, thence south 15 1/2 degrees east 100 chains, thence north 74 1/2 degrees east 116 chains and 50 links, thence north 15 1/2 degrees west 58 chains to the place of beginning, and containing in all 1165 acres of land …”

The location and angle of Anaheim was chosen to make the main wagon trail from Los Angeles to San Diego go through the center of town. The location also allowed a down-sloping irrigation channel to bring water from the Santa Ana River. The nearly square boundary was originally a living fence made from thick rows of willow, with a gate on each side, to keep the cattle out. The paths around the fences eventually became the North St, South St, East St, West St of early Anaheim. There is a plaque marking the “San Pedro Gate” on the west side, that stages and horse-drawn wagons moved to and from the Port of San Pedro, or the closer Anaheim Landing in Seal Beach. Anaheim vinyardists hauled their wine several miles to the landing for shipment to San Francisco.

Here is a excerpt from “The German Settlement at Anaheim” by Dorothea Jean Paule.

Anaheim Transportation

To transport products of Anaheim to market was a major problem. Roads in the early days were little more than wagon trails and did not allow for rapid transportation. Rivers had to be forded for lack of bridges, and there was constant danger from bandits. There was a stage carrying mail and express which passed through the colony every Tuesday from San Francisco and Los Angeles to San Diego, returning through on Saturday. There was also passenger and express service to and from San Pedro, thirty-five miles distant, on the arrival and departure of the steamer from San Francisco. This service, however, was far from adequate for shipment of viticultural produce to the main Pacific Coast port, San Francisco. Ocean travel was the only expedient means of transportation from the southern coast to the metropolis of the north. It was essential that Anaheim have a seaport, not only as a point of embarkation for products being sent to market, but also as a receiving point for goods and materials needed for the course of living in the colony.
It was very shortly after the first residents arrived at their Anaheim homes that search for a near seaport began. In the January 4, 1860, edition of the Daily Alta California, complaint was registered in a letter from an Anaheim resident of having to trade at San Pedro. “Some of our citizens are going down soon to the beach – only ten miles distant – to see whether we cannot have a port of our own. ” At one time in the quest for a port closer than San Pedro, a site fifteen miles east of the colony was examined. This location was sixty miles from San Bernardino, twenty miles from San Juan Capistrano, and thirty-five miles from El Monte. There was an estuary here of one-half mile which entered into the land for a distance of eight or ten miles. A sand spit half a mile wide ran parallel with the shore at this point. Water inside the spit and in the estuary was about twenty feet deep. A chart was made of this location and displayed in the store of J. P. Zeyn and Co. in Anaheim, and it was agreed that the Superintendent of Coast Survey should be asked to have the place examined. It was rumored that silver mines were discovered between Anaheim and San Juan Capistrano, and an agent of a company of miners who wanted to send machinery for crushing and amalgamating auriferous quartz in Bear Valley in San Bernardino County also examined this prospective port to see whether machinery could be landed there.
The Los Angeles Star on February 23, 1861, mentioned that a project for a landing on the coast about twenty miles from Anaheim was temporarily given up, but not abandoned, “as the trade to the tin mines, San Bernardino, etc. may yet render it necessary.” It is possible that this is the same location as that stated above as fifteen miles from the settlement.
A site for Anaheim’s port was ultimately selected in October, 1864, on the ocean twelve miles south of the town. The Anaheim Lighter Company was formed in the early sixties by citizens of the community for the purpose of financing this port. Each member of the company was assessed to build a and from the steamers which called at the port, one end of the cable being fastened at the warehouse and the other anchored near where the steamer would stop. Eight or ten men pulled the cable. Depth at the port was seven feet in the slough at low tide. A hard, level road was built across the twelve miles to the Landing. At last a shipping point for wine, corn, wool, and other products not only from Anaheim but also from the neighboring country was established. Freight was landed at this port for points as far distant as Salt Lake City, being taken by wagon team to San Bernardino and by pack mules from there to Salt Lake City. A record from the year 1872 shows that thirty or forty teams were making the trip daily from the Landing to Anaheim, and one day’s report mentioned seventy teams. Usually two coast steamers stopped at the Landing each week. Anaheim Landing served Los Angeles, San Bernardino, and Arizona, as well as Anaheim, for many years, but never achieved a major seaport name for itself. The Lighter Company was terminated with the coming of the railroads to Anaheim.

The Southern Pacific Railway came to Anaheim with a branch in January, 1875, its terminus there for nearly two years before it extended to Santa Ana. The community had wanted a railroad for many years, so when the Southern Pacific constructed this branch, there was great rejoicing. The editor of the Anaheim Gazette in relating the advent of the railroad wrote: … there is assured a paradise of wealth and refinement in Southern California. All praise to God, who, after years of frowning, smiled upon our land with an exceedingly gracious smile. Santa Fe built its road into Anaheim in 1887, and as a result of its depot being some distance out of town, the boom hotel, Hotel del Campo, was built and a streetcar company organized with a track down Center Street connecting the stations of the two railroads.
Just as Anaheim needed a port, it needed an irrigation system, for without irrigation there could not have been an agricultural colony at Anaheim. The colony site near the Santa Ana River was selected because of proximity of water. Procurement of water from the Santa Ana was of vital importance in the early days and continued to be important for many years in the life of Anaheim, until the population of the Santa Ana Valley became greater than the river could adequately supply.

Kirkman 1860 Map of Los Angeles County

This is one of the best historical maps of Los Angeles County, compiled by George W. Kirkman in 1937. Towns in parentheses were not founded until after 1870.

  • Portola’s first exploring route is shown as a thick red dashed line with flags at each campsite.
  • El Camino Real (official Spanish roads) are shown as double red stripe.
  • Mission roads (created before 1851) are shown as double green stripe.
  • Old roads (from ancient, up to 1890) are shown as a thin double black stripe.
  • Historic battle fields, Indian villages, gold mines are also shown.
  • Look up your neighborhood to see what it once was, if anything besides empty land.

The Camino Real turned north in Tustin, and crossed the Santa Ana River in Olive.
Then it went northwest through Whittier. There a branch went north to San Gabriel.
Layer 4: Over that are 1830-1870 towns, stagecoach routes and wagon roads.
Anaheim-San Pedro road ran southwest to Anaheim Landing and Port of San Pedro.
Anaheim-Los Angeles road became Harbor Blvd, merging with Camino Real.

 

 

Stearn’s Ranchos Maps

Abel Stearns was born in Massachusetts in 1798, and moved to Los Angeles in 1829. He bought his first rancho, Los Alamitos, from Juan Jose Nieto in 1842. He bought more ranch land from Nieto in 1853. By the 1860’s, Abel Stearns owned much of the land in the Los Angeles basin. Besides being a cattle rancher, businessman, and land developer, Stearns was also a talented amateur surveyor and map maker. His maps were made independently, and so include certain things that other maps do not. Stearns chose to include or omit things on the map, ultimately to sell parcels of land. Having accurate, complete maps would help sell the parcels. Also helping to increase the lands value was creating a one square mile grid of access roads, orientated north and south, east and west. The property boundaries (grid lines on the map) were dirt access roads that later became the major streets of north Orange County. Some of them are still called “road”, such as Ball Rd.

One Mile Square Grid: If you are familiar with northern Orange County, California then you know how easy it is to navigate and estimate distances with the square grid of major streets spaced one mile, and minor streets spaced 1/2 mile apart. You can thank Mr. Stearns for that.

First Standard South

First Standard South is 2 miles north of Red Hill (Cerrita de las Ranas), a rancho corner point.

Garden Grove Blvd: Garden Grove Blvd is on a major survey line called First Standard South, which is exactly 24 miles south of the San Bernardino base line. Somehow the survey teams north and south of the line did not know or care that they disagreed with each other. The squares north of Garden Grove Blvd do not line up with those to the south. As a result, all of the north-south streets had to end, turn left, and resume a block over, at Garden Grove Blvd. Since the 1950’s most of those have been made to gently curve left where they cross, so that a non stop flow can occur, on a green light. A few have been made to curve way to the right. Other than that, everyone loves the square grid street system.

The Horse-Drawn Wagon Roads: Whether you had a pony, a horse, a mule, an ox, a donkey, a burro, a horse drawn carriage or wagon, or a team of horses or mules pulling a carriage or wagon (the bus or big rig of the day), you took bumpy dirt roads and had to cross rivers and streams. Crossing places were chosen with hard flat bottoms. It took three days to go from Los Angeles to San Diego by stage, with two overnight stops. So going 40 miles then, averaging 5 mph, was an 8 hour trip. That was like driving 400 miles today at a 50 mph average, time-wise, but felt worse because of all the bumps. If it had rained recently then the streams would be too deep to cross. So you would not be able to go certain places, until the streams and rivers returned to normal. Only some river crossings had bridges, on well used major roads.

View of Olive in about 1880. Olive is the oldest non-native community in Orange County besides San Juan Capistrano.
The view is east, looking down what is now Lincoln Ave on the right, with Orange-Olive Rd crossing to the left.
In 1780 this was a junction on the El Camino Real that 100 years later became this bustling American community.

Railroads revolutionize transportation: What a difference those perfectly flat straight and smooth steel rails make, compared with hard packed dirt, or sometimes mud or sand. Railroads came to Los Angeles in the late 1860’s. First was the north-south straight line from Los Angeles to San Pedro. More to follow about railroads and stagecoach routes…

The Oldest Roads in the Area:

Portolá Routes (green dot dashed red line) The Portolá Expedition made two journeys in 1769 and 1770, looking for places for missions and settlements. Along the way they charted the land and named all of the places they saw. The routes hugged the hills and often crossed into and over the hills. The Kirkman 1860 Map above shows the Portola routes 1 and 2, and the campsites with the dates they stayed at. Most of the El Camino Real followed the Portola Routes, but not where it crossed over hills.

One can only imagine what Gaspar de Portolá, Father Crespi, and soldiers Manuel Nieto, José Antonio Yorba, Juan José Domínguez and the others were thinking as they walked. Was it easier to cross streams where the ground is sloping? Yes. Were there less swamps and marshes where the ground is sloping? Yes. Could you see distant landmarks better when on higher ground? Yes. Were you more likely to find natural resources such as edible plants and animals, minerals, wood, or even gold? Yes, if you were lucky. 

 

El Camino Real (viejo) (purple dot dashed red line) The original 1771 camino real viejo (old royal road) stayed close to the hills. From Mission San Juan Capistrano it went first north following San Juan Creek, past Rancho Mission Viejo, Rancho Trabuco, Rancho Niguel, and then turned northwest through Rancho Cañada de los Alisos, and through Rancho San Joaquin (later Irvine Ranch) to just before Tustin. 

From there the ECR turns north to get around the marsh called “Cienega de las Ranas” and passes close to Red Hill. It becomes Foothill Blvd, then Old Foothill Blvd, followed by Hewes Av, passing close to El Modena (now Panorama Heights), Hewes St, through Orange, across Santiago Creek, through Villa Park, along Santiago Blvd to Olive. The “Old Santa Ana Site”, at present day Orange-Olive Rd and Lincoln Ave, is where the Yorbas and the Peraltas built their adobe homes, creating the first settlement after the founding of Mission San Juan Capistrano in 1776. The original Camino Real passed by there, and crossed the Santa Ana River at the community of Olive. It says that on the “Old Santa Ana” site marker there, shown above. Visit “Olive through the Ages” at http://dragoon1st.tripod.com/olive/menu.html.

Santa Ana River historic crossing point near Olive

Santa Ana River crossing

The 1770’s crossing point and route through Placentia is only estimated, with a dashed red line. The evidence for that is the “Old Santa Ana” site marker inscription, the 1855 Anaheim Site Map and 1852 Diseño of Rancho San Juan Cajon de Santa Ana, all shown above, and the graphic on the right. They show the El Camino Real (viejo) through Placentia, but not accurately. The alternate crossing point farther east upstream must have been used in the early 1800’s, because there was no trace of the 1700’s crossing and road on the earliest 1896 USGS Topographic Map. The bedrock mouth of the Santa Ana canyon held the river steady there, but further down it was free to change directions, and did after large floods. That could explain how the original river crossing place and trail segment became unused, erased and forgotten.  

After crossing the Santa Ana River (originally called “Rio de los Temblores” river of earthquakes), the ECR went north through Placentia, through Rancho San Juan Cajón de Santa Ana, turning westward at Palm Dr, then skipping over Fullerton Creek to form part of Imperial Hwy, in Brea. A short piece of east-west running Lambert Rd is on the trail. Then it angles northwest through the La Habra valley, and becomes the eastern end of Whittier Blvd.  This route follows the hills, but does not hug them, like the exploratory route taken by Portola. Later years would see the camino nuevo coming north up Harbor Blvd, to rejoin with the camino viejo in La Habra. Northwest through Rancho La Habra it passed by 201 E La Habra Blvd, the birthplace of La Habra. A historic marker there says “The first post office, officially naming this settlement “La Habra,” was granted in 1896 and was established in a corner of Coys Store, located on this site. El Camino Viejo, the old road between the missions, passed this corner, which became a central trading point in the fertile La Habra Valley.” Further on northwest, the trail would come to be known as Whittier Blvd, through Whittier and Pico Rivera.

After crossing the San Gabriel River (which changed course in places after floods), the ECR continues still in a northwest direction, following Whittier Blvd all the way into East Los Angeles. There Telegraph Rd used to meet Whittier Blvd. Before that it was the junction of El Camino Real (abajo) and El Camino Real (viejo). Skipping over to Boyle Heights, the trail approached  “El Pueblo de Nuestra Señora la Reina de los Ángeles” (the Town of Our Lady the Queen of the Angels), along what is now Ceser E Chavez Ave. From Los Angeles the El Camino Real continued northwest along Sunset Blvd, through Hollywood and the Cahuenga Pass, along the 101 Hollywood Freeway towards Mission San Fernando.

    

El Camino Real bellEl Camino Real (nuevo) (white dot dashed red line) Sometime, perhaps around 1775, el camino real nuevo (the new royal road) came into use. It did not stay close to the hills, like the camino viejo. In Tustin it split off from the camino viejo, and headed north-west, instead of north.  It passed through what later would become Santa Ana. El Camino (nuevo) Real crossed about 4 miles downstream of El Camino Real (viejo), and then turned almost north, to pass through what later would become the centers of Anaheim and Fullerton. The new Santa Ana River crossing point allowed a straighter path from Tustin to Los Angeles that was about 3/4 the distance. It soon replaced the camino viejo.

The official El Camino Real route, in Wikipedia, is  I-5 to Anaheim, Anaheim Blvd, Harbor Blvd, Whittier Blvd to Los Angeles. South of La Habra and north of Tustin, the official “El Camino Real” is not the original camino (viejo). The official “El Camino Real” is the camino (nuevo), there. In La Habra the camino nuevo merges with the camino viejo. So north of there they are the same, and the official ECR is el camino real viejo, the old royal road.

 

 El Camino Real (nuevo abajo) (yellow dot dashed red line) Sometime, perhaps around 1780, el camino real nuevo abajo (the lower new royal road) came into use. South of Anaheim, el camino nuevo abajo splits to the northwest, from the northbound camino nuevo. This path follows a more straight line to Los Angeles, by crossing the San Gabriel River at a lower point, and just missing the southwest corner of the Coyote Hills in Buena Park. It follows the I-5 from Anaheim northwest, up to Gilbert St, then splits more north, passing under the 5-91 interchange and through Buena Park High School just north of Magnolia and Orangethorpe. Part of Dale Ave is the camino nuevo abajo, where it curves, for no reason, at the west end of the Fullerton Airport. Parts of Malvern Ave, La Mirada Blvd, and Rosecrans Ave were the trail. Further north through Santa Fe Springs, Meyer Rd and then the northern part of Telegraph Rd were the camino real (nuevo abajo).

 

Evidence of El Camino Real (nuevo abajo) through Buena Park and La Mirada

Evidence of El Camino Real (nuevo abajo) through Buena Park and La Mirada

2. Modern Map – La Mirada Blvd and Malvern Ave are the old trail on the 1870 map
3. (maps 1 & 2) Combined 1870 Stearns Ranchos map with illustrated modern roads
4. 1896 USGS Topographic Map – provides accurate terrain and scale for a base map
5. 1860 Kirkman Map – provides El Camino Real versions and trails, but not accurate
6. (3, 4, 5) Combined Historic and Modern All-In-One – map 4, with 3 & 5 illustrated

 

The above mosaic of six small maps of the La Mirada – Buena Park area shows the process that was used throughout the large map. By comparing landmarks, maps are correlated in scale and in position. Once the known landmarks agree, then historic items can be be illustrated onto a modern map, or modern items can be drawn on a historic map. It’s like having clear sheets or layers, over a base map. Peeling back the clear sheets is literally turning the pages of history. 

 

The camino real nuevo abajo crosses the floodplain of the San Gabriel River at Telegraph Rd, about 3 miles south of where the camino viejo crosses at Whittier Blvd. So the northern part of Telegraph Rd is older than the telegraph. Further on northwest it passes through Pico Rivera, Commerce, then East Los Angeles, where the camino abajo rejoins the camino viejo at Whittier Blvd near Gage Ave in East Los Angeles.

Jawa Chain: The Jawa motor chain is not a standard 415 moped chain, although it has the same pitch and width. It has thicker pins, 4.4 instead of 4.1mm. More importantly, it has bigger rollers, 8.4 instead of 7.7mm. Because the Jawa sprockets are made for bigger rollers, they look similar to worn out standard sprockets. The valleys between the teeth are wider and deeper, making the tops of the teeth more pointed. So a 415H moped chain will work OK, but not great, on unworn Jawa sprockets. But if the Jawa sprockets are worn, the chain might skip and jump off.

Jawa Center Stands

Left, Jawa 207 37 150, swing arm type stand, goes outside the frame
Right, Jawa 28-3400, rigid frame centerstand, goes inside the frame

Chains opposite: See below about how the Jawa pedal chain is on the left side of the bike. and so is not like most other mopeds and bicycles. Weird!

Motor chain is special: See above and in the link to Chains, how the Jawa moped chain has bigger rollers than all other mopeds. Weird!

Jawa brake shoes
L, 2.5 lining for Ø85 drums
(on Jawa spoke wheels)
R, 5.0 lining for Ø90 drums
(on aluminum wheels)

Jawa Spokes: Jawa spokes for 16″ rims are all 160mm long (198mm for 19″ rims). There are two kinds, inner and outer. The outer ones go through the hub holes from inside to outside, and have a longer and sharper bent section. The inner ones go through the hub holes from outside to inside, and have a shorter bent section. Each wheel has 18 inner and 18 outer spokes, alternating, for a total of 36. It was an educated guess which part number was for which type. Inners were 07-4016 and outers were 07-4022, at least in this list. Nowhere else is this difference noted. It does not matter much, since either type of spoke will work, with some minor bending during tensioning/truing. 

Jawa Freewheel

Jawa Brakes: Jawa brake shoes are not like any other western European or Asian brake shoe. Most are for a 85mm drum diameter. Some Jawa mopeds with aluminum “mag” wheels have 90mm drums. For those Jawa made the same brake shoes, but with thicker lining, 5mm instead of 2.5. 

Jawa Left Hand Freewheels made by Velo

Jawa LH 18T Freewheels made by Velo, say what year they were made, here 1976, 77, 78.

Jawa Freewheel: The “free wheeling hub” with sprocket, for the pedal chain is on the left side of the bike. All other US mopeds, except Benelli, and virtually every bicycle, with a freewheel, has a pedal chain on the right side. A right side freewheel screws onto a hub and tightens clockwise, as the bike is pedaled. So the hub has a standard right hand thread. But a left side freewheel needs an opposite thread, so it tightens counter-clockwise, as the bike is pedaled. Jawa specifies the freewheel thread in the Model 28 Parts List. It is M35 x 1.0 L.H. (left hand). So Jawa freewheels and rear hubs are special.

Notice how the back side of a Jawa freewheel, lower right, looks like the front side of a conventional freewheel, top left, except for no removal slots. For many years Shaun mistakenly thought Jawa freewheels were conventional right hand thread ones that were missing the removal tool slots. It is not easy to tell the direction of such a fine thread. Tragically some of those special left hand freewheels got thrown away in the 1990’s along with a few Taiwan bicycle ones that were truly missing the removal slots.

Just a reminder, freewheels tighten by pedalling. No tool is needed to install one. But removal requires a special tool, which comes in different styles and sizes. If the bicycle or moped is pedaled hard, then the freewheel will become very tight and difficult to remove.

Each cable was made in long or short versions. Long is for tall hi-rise handlebars like on the 207.311.
US models 1976-81 had Jawa controls. Those had inline brake light switches on the brake cables.
US models 1982-83 had Domino controls. Those had brake light switches on the controls, not the cables.
The 1982-83 top tank had low bars, short cables. The 1981-83 step thru had high bars, long cables.

Jawa Magneto Coils

Jawa Magneto Coils

Jawa 207 magnetos have four source coils (and one pulse coil). Two of them are combined in series to make one. So there are three independent generator outputs, ignition (coil 4b), lighting (coil 7a plus 7b), and horn or brake light (coil 6). The ignition never has anything to do with the lights. The brake light does not make the head light dim at all. So it is like three separate little generators, all in one place. More about Jawa electrical can be found in the Wiring Diagrams gallery. Scroll down to “J” Jawa.

Jawa Service Bulletin Aug 1981

Jawa Ignition Upgrade Kit

Jawa Ignition Upgrade Kit

In 1981 Jawa moped dealers across the US were sent this Service Bulletin #1. It says how to update pre-1978 (model 207.011) ignitions by replacing the old red Tranzimo unit, and the old stator ring with pulse coil, with the newer system, shown at right. The new system had been in use for two years on the 207.111 models, and was proven to be more reliable. Too bad MM does not have any more of those ignition upgrade kits.

Frequently Asked Questions

August 22, 2015

Do you have any 6 volt ignition coils?

No. A 6 volt coil is for a 6 volt battery ignition. The only vehicles that I know of, that have 6 volt ignition coils are vintage ones from before the 1970’s and 80’s. 1980’s and later cars and big motorcycles all have 12 volt ignition coils. Big motorcycles, like cars have “battery ignitions” where the ignition power source is a battery. Small motorcycles and mopeds have “magneto ignitions” where the ignition power source is a generator. The ignition coils for small motorcycles and mopeds do not say any voltage.

Do you have a rebuild kit for my engine?

You cannot accurately guess what it needs. You will need to get a tech person to:
1. Get the engine unfroze
    feel if it has compression, if not then

2. Disassemble and diagnose what is bad

the least might be just piston rings, which I have

    if the crankshaft and cylinder are bad, then it is not worth fixing
I do not have a engine for sale. Generally, you need to find another whole bike to get that. You hopefully won’t need an engine, but you do not know yet. There is not any engine/transmission that I know of that would fit, although people do occasionally put an engine from a different bike. That requires engineering skills and some luck. For any given moped or motorcycle, the engine costs almost as much as a whole bike.

Do you have the original ignition coil for my moped?

Chances are that if you did find the original ignition coil, and put it on, it would still have the same problem. That coil does not have to be the original one. Any ignition transformer coil for a magneto points ignition (not a 6V or 12V battery ignition coil), would function, if the rest of the ignition was good. Read about ignition troubleshooting online and on my website. Get help from a technical person if necessary. Here are the most likely causes of weak or intermittent spark:

Is there an external ignition ground that goes outside to power the brake light, that must be grounded to get spark?

Is there continuity through the points, when they are closed? Or are they “dirty”?

Is the condenser bad, causing heavy sparks to jump across the points?

Do the points even open enough, or is the points cam rusty, and the points wiper worn so there is no gap?

Has the flywheel been put in the wrong position, so that the spark is at the wrong time, and/or weak?

Has anything been changed, like a different flywheel?

These are the likely things, in order of most likely first.
