US-model Peugeot mopeds were made in three different speed and power versions to comply with different state laws. For example, mopeds in California go 30mph, but in Nevada or Arizona they go 25mph. Each state has different moped laws. Peugeot moped speed versions are referred to by the speed version codes U1, U2 and U3. The speed version code appears after the model on the I.D. plate, on the frame behind the headlight. For example, a 103 LVS U2 is a 25mph moped with 1.5 horsepower.

U1 is 20 mph and 1.0 hp, U2 is 25 mph and 1.5 hp, U3 is 30 mph and 2.0 hp

Cylinder: 102 U2 and U3 are the same, but 103 U1,U2 have a different cylinder than 103 U3, with a slightly smaller exhaust port. A U1,U2 cylinder can be converted to U3 by mild “porting”, by grinding the top pf the port, at the cylinder wall, higher by 1.0 mm, and each side wider by 0.5mm.

Head: The 103 U1,U2 low compression head can be converted to U3 by milling off 1 or maybe 2 mm. Leaving off the head gasket instead, is a quick and beneficial way to increase the compression ratio. But when the head is moved closer to the piston, contact can happen. Care must be taken. A squish clearance of 0.6mm (0.024″) is recommended when cold. A minimum combustion chamber volume of 5.0cc is recommended for a 50cc swept volume, to have a maximum compression ratio of (50+5)/5 equals 11 to 1. 

Reed Valve:  The 103 U1 and U2 small round reed plate holes can be widened to “normal” round holes. Furthermore a Tomos A35 reed valve fits, and gives even more power increase because the reed plate holes are rectangles with more area. Expect a stock healthy 103 LVS U3 to go 4-5 mph faster and accelerate quicker, with just a Tomos reed valve, with no side effects.

Carburetor: To upgrade an 8.5 to a 12mm carburetor you can replace the bare body. It is too difficult to carve out because the non-removable brass spray tube is in the way.

Intake Pipe: To upgrade an 8.5 to a 12mm intake manifold you can carve out the inside, or replace it. On a Peugeot 102 the only difference between a U2 and U3 is the intake manifold.

Exhaust: The 103 U1 muffler is gloss black and has a U-turn in the removable baffle, and a hemispherical end cap. The 103 U2 and U3 muffler is dull black, with a straight tube removable baffle and a vertical channel end cap. The wider end of the vertical channel should face down, or the bike will go slower.

Baffle tube: Early 103 U3 models came with a short baffle tube. These went 35mph and were the fastest moped. Then in 1978 Peugeot had to slow all the bikes down to meet 30mph DOT requirements. They issued a recall to all 103 U3 owners to bring their mopeds into their dealer to have the long baffle put in. All later 103 U3 models were made with long baffles. Simply removing the baffle makes it only a little bit louder, but adds 2-3 mph in speed.

Belt Pulleys: The front pulley is the same on all 102 and 103-no-variator models. The variable front pulley on 103-variator models is the same except for the centrifugal variator weights are different on U2 and U3 models. All 102’s have the same 7 inch rear pulley. All 103’s have the same 8″ rear pulley.

Sprockets: All Peugeot’s have an 11 tooth front sprocket. 102 rear sprockets have smaller center holes than 103 rear sprockets (because the rear hub is smaller). 103 rear sprockets can interchange with Puch or Motobecane, except for the bolt holes. On both 102 and 103 Peugeot uses a special 5-hole pattern that is unique. They did not want people to easily change to a 6-hole Puch 45 tooth rear sprocket. It can be done with drilling.

Gearing: A smaller rear sprocket makes higher gearing, and higher possible speed. But if the gearing is already optimum, then higher gearing alone will not make any more speed, except on downhills and with tail winds. It takes a greater amount of driving force to push through the air at a greater speed, but higher gearing decreases the rear wheel driving force. So the engine has to make much more torque to achieve the higher speed.

Gearing: 102 and 103 no-variator have the same size front pulley, but the rear pulley is bigger on the 103, about 8 inch, while 102 is about 7 inch. So a 102 rear sprocket must be bigger by 8/7 to have the same overall gearing as a 103. That is why 102 rear sprockets are bigger than 103 no-variator ones.

Here is a beautiful cut-away illustration from the Danish website veteranknallertklub.dk. The venturi is 12mm diameter. The curved pipe is about 13mm. The jet and jet holder are a single piece, like the Bing “early Sachs”. The choke cable and plate are the same as Bing “Solo”, with a “carb” end on the choke cable. The screw-on top cap is M18x1.0 thread and M6x0.75 cable elbow/stop, Ø14.5 slide with slot facing the intake (like other early Bings), and jet needle, are interchangeable with Bing “Solo” and Bing “Jawa or early Sachs”.

From the left drawing, sliced vertically front to back, you can see the little pin that locates the throttle slide, near where the choke cable comes in at. Like the other early Bings “Solo” and “Jawa”, the slot in the throttle slide faces the intake, so the throttle slides interchange (but not with “1970’s Sachs” and “Kreidler”). 

Puch used this Bing “Allstate” 12mm carburetor on the MS50 (Moped Stahlblech – steel sheet) series from the 1950’s to the 1970’s. In 1969 Puch indroduced the Maxi moped, with an all new carburetor design. That carburetor, called Bing “Puch” or “round Bing” was in use from 1969 to 1986. It is way more familiar to Americans because of the moped buying frenzy in the late 1970’s. In the early 1980’s Puch developed their advanced technology future moped. But sales were down, and something like internal fraud contributed to Puch going out of business after over a century. If they had kept going, we would have an abundance of parts for the Bing “Austro Daimler” carburetor.

Minarelli

Minarelli is the name of the engine. Only the lower end of the throttle and start cables are for the engine. The cables upper ends are for whatever controls that are on the bike’s handlebars. The brake cables lower ends are for whatever brakes the bike has. The cable lengths depend on the frame and handlebars.

Cables for mopeds with Minarelli V1 engines, 1970’s Domino controls and Grimeca brakes, are in Cimatti.

Cables for mopeds with Minarelli V1 engines, 1970’s Taiwan controls and brakes, are in General or Lazer.
