A. Screw-on Gas Valves

A1. 8x1 male spigot L or R push-pull

A2. 10x1 male spigot down

This valve fits hundreds of mopeds and mini-cycles. It fits any tank with a 10×1 threaded hole, and with nothing below or near the valve that would interfere.

This modern replacement valve has 3 positions, ←reserve  on↓ off→. Most original valves were, ↑reserve  off→ on↓ . Original valves with an up position had to be moved away from the bottom of the tank with an extender, to allow the handle to go straight up. Some tanks had a welded-on extender, a short pipe with a 10×1 threaded hole. Some valves had a screw-on extender. On tanks that needed an extender for handle clearance, this modern replacement valve eliminates the need for an extender, by not having an up position.

 

 

 

 

 

 

 

 

 

 

 

 

Cimatti rear tanks have a 10×1 threaded hole, but there is a nearby “wall” that prevents a 10×1 male valve from screwing in, unless the whole gas tank is removed. That requires rear wheel and rear fender removal. To make gas valve installation easy, Cimatti added a screw-in 10-to-12 adaptor piece, and used a 12×1 female type gas valve, with a turnbuckle type nut. Only the nut turns, and the “wall” does not matter. So it is much better to reuse the 10-to-12 adaptor, and use a 12×1 spigot right valve, see below.

A4. 10x1 male spigot left

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

These valves fit 1970’s sheet-metal-frame Motobecanes, where there is a tight space.

 

 

 

 

 

 

 

 

 

 

 

 

 

These “spigot left” valves substitute for a “spigot back” type in many cases. The fuel hose goes left instead of back. Like all screw-on valves, it can be aimed at any angle, so “left” can become “back”.

A6. 10x1 male spigot back extended shaft

 

 

 

 

 

 

 

 

 

 

 

---

A7. 10x1 male spigot down with 15mm extender

This valve fits early Tomos top tanks 10×1 female threads. The round knob goes through a one inch hole in the right plastic panel below the tank. After 1993 the top tanks had 12×1 male threads.

Here it is shown without the metal cup and rubber ring, but those things are included. The 15mm length extension includes the cup and rubber.

 

 

 

 

 

 

 

 

 

 

 

 

 

---

A8. 10x1 male spigot down with 20mm extender

 On Peugeot 102 and others there is a wall that prevents the valve from being screwed in, unless there is an extender piece between the valve and the tank. You try not to loose the extender, because it costs more than the valve. 

 

 

 

The AMF Roadmaster 140, 141 is another model that needs a short extender to position the valve knob to go through the hole in the body panel. That hole might have to be widened or the knob made smaller for this valve to fit

 

 

 

 

---

A9. 10x1 male spigot down with 26mm extender

This 10×1 spigot down valve has a 26mm extender that positions the valve lower, away from the bottom of the tank. The 26mm extender includes a longer reserve tube.

When an extender is added to a valve, the reserve tube needs to be longer. When the reserve tube is too short, there is little or no reserve. Here the original reserve tube has been replaced with a longer one, 60mm from the valve base instead of 35mm.

Any of the other 10×1 male valves can have a 15, 20, or 26mm extender added. Some already have long reserve tubes.

A10. 10x1 male spigot left with 26mm extender

At left is a used leaking original, not for sale. An unknown application.

At right is a new replacement, for sale. It is either a 403200 (shown) or 01z2351035 (red) valve, with a 1 inch extender.

It includes a 1 inch longer reserve tube and both outer seal rings.

A11. 10x1.25 male spigot right

 

This valve fits tanks with M10-1.25 female thread

None of the mopeds on this site have this thread. It may be for Chinese motorized bicycle gas tanks.

No reserve just OFF and ON.

Nut adjusts vertical height to fit closer or farther from tank.

Direction adjusts 360 degrees (like most others).

 

 

 

 

 

 

 

 

---

A12. 12x1 male spigot down

This 12×1 valve is a male thread, right hand (clockwise is tighter). All other 12×1 valves are female thread and have a turnbuckle nut with both left and right hand thread. With the turnbuckle nut removed, the other 12×1 valves are male thread, left hand (clockwise is looser).

Because the whole valve must be screwed in to install it, the handle knob detaches with a clip.

 

 

 

 

 

 

 

 

 

---

A13. 12x1.25 male spigot left

 

 

 

 

 

 

Speedbird BP48 and Angel BP48-S, tube frame models made in Taiwan by TYM, use this valve. The 1.25 thread is more coarse than 1.0.

A custom made adapter, 10×1.00 female to 12×1.25 male thread, can allow a 10mm spigot left gas valve to work on a Speed Bird. The price is $25 for the adapter and seal washer, plus $15 for the valve.

A14. 12x1 female spigot down

This valve fits hundreds of mopeds. It is sometimes called “universal”, but it is not truly universal.

A16. 12x1 female spigot back with clear trap

This valve has a clear sediment trap. Anything heavier than gasoline, like water, dirt, rust settles at the bottom. The trap not only filters, but allows visual monitoring of the fuel for purity.

A17. 12x1 female spigot left

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The original valve on a Columbia Commuter (tube frame) was a vertical mount valve, mounted in the sideways position. So the valve faces up, instead of sideways. That is not bad, but the poor handle gets kicked easily since it is right where you step through the frame at. 

The original valve had a reserve tube that curved upward, like on a Puch side mount. The replacement valve has a short straight reserve tube. Sideways installation disables the reserve feature. Optionally, a longer curved soft aluminum reserve tube is available. See below.

A18. 12x1 female spigot right

 

 

 

 

 

 

 

 

 

 

 

 

This sheet metal frame Columbia is different from a tube frame Columbia. It can have different marketing names. Original valve was spigot right, but down, back, or left also fit.

All Tomos models with the A55 engine have a 12×1 spigot right gas valve #233727, above the left side of the engine. Earlier A35 models had a opposite valve on the opposite side. 

 

 

 

 

This screw-on valve is for Vespa Bravos with a metal tank. Some have a plastic gas tank, with a different gas valve than this. See clamp-on valves below.

 

 

 

 

 

 

 

 

 

 

Bermuda (made by Flandria) mopeds use this vertical 12×1 spigot right valve, but in the horizontal position. There is no reserve function. The owners manual says that either rear or forward is closed (off), and outward is open (on). The valve handle is protected behind the cover. There is a finger width long slot in the right cover, for one-finger access. Many have their gas valve access slots widened, like the blue 1978 above.

A19. 12x1 female spigot back short extended knob

This valve is made for the 1980-85 Garelli models with side panels that cover everything up to the bottom of the gas tank. The valve handle shaft passes through a hole in the panel.

A20. 12x1 female spigot left medium shaft

 

 

 

 

 

 

 

 

 

 

 

 

The Vespa Grande has a vertical type valve, but it is mounted at an angle of about 60 degrees from vertical, or “2 o’clock”, as seen in the red frame photo.

 

 

 

---

A21. 12x1 female spigot right medium shaft

 

Although the spigot direction is wrong, this still works fine on a Vespa Grande. The gas has to go uphill a little at first. This would only matter when nearly empty.

While the Tomos Targa valve works on a Vespa Si, the opposite is not true. The Tomos engine is too close, unless the cover is left off and the valve is rotated.

A23. 12x1 female side mount Ciao

This valve fits a Vespa (Piaggio) Ciao. It can also fit a Puch Maxi type frame, but the upper filter hits the inside upper wall of the Puch gas tank. The reserve tube, which is a light press fit, can simply be rotated so it is not aimed straight up, to allow a Ciao valve to fit a Puch.

A25. 14x1 female spigot down

This spigot down valve was original on 1979-81 Honda NA50 Express II. It also replaces the original spigot left on Honda NC50 Express, and the original spigot right on Yamaha QT50 Yamahopper.  

 

 

 

 

 

 

Honda Design: Note that the little arrow on the handle points opposite to the handle. So off is arrow left (handle right), on is arrow up (handle down), reserve is arrow down (handle up).

This valve has a 6.0mm spigot, for 3/16″ (4.8mm) hose.

 

 

 

---

A26. 14x1 female spigot left

This spigot left valve was original on Honda NC50 Express.

 

 

 

 

 

 

This valve also substitutes for other 14×1 thread valves, including Yamaha QT50 (spigot right), Honda NA50 (spigot down), Trac Eagle (side mount), and most Taiwan-made mopeds (mostly spigot back).

Honda Design: Note that the little arrow on the handle points opposite to the handle. So off is arrow left (handle right), on is arrow up (handle down), reserve is arrow down (handle up).

This valve has a 6.5 mm spigot, for a 3/16″ (4.8mm) hose, or a 1/4″ (6.3mm) hose with clamps.

 

 

---

A27. 14x1 female spigot right

This valve configuration was original on Yamaha QT50, early Yamahas and Hondas, and early Taiwan mopeds. It can replace other 14×1 thread valves, in most cases.

This motorcycle fuel valve has a 7.7 mm spigot, for 1/4″ (6.3mm) fuel hose.

 

 

 

 

 

 

Honda Design: Note that the little arrow on the handle points opposite to the handle. So off is arrow left (handle right), on is arrow up (handle down), reserve is arrow down (handle up).

 

 

 

---

A28. 14x1 female spigot back

The original valves had poorly made cast nuts. The nuts were too big and also weak. When fully tightened they would strip. Some have good nuts, but after 35 years the rubber seal disk inside is brittle and deformed. All of the mopeds listed that came with a spigot-back gas valve, can take a less expensive spigot down or spigot left valve.

This motorcycle valve has a 7.7 mm spigot, for 1/4″ (6.3mm) fuel hose.

Honda Design: Note that the little arrow on the handle points opposite to the handle. So off is arrow left (handle right), on is arrow up (handle down), reserve is arrow down (handle up).

A29. 14x1 female side mount

The upper one is an original Trac 14×1 side mount, made in Korea. All their inner seal disks have decomposed. The lower one is a modern Honda substitute, made in China. It is a 14×1 vertical mount spigot left mounted sideways.

The cover panel must be removed, or a large hole cut, to allow access to the substitute valve.

There is no reserve capacity on the substitute, since the reserve tube is horizontal. A soft aluminum reserve tube that curves upward is optional, for an additional $15.

A33. 16x1 female side mount

 

 

 

 

 

 

The upper one is an original Paoli 16×1 side mount valve, made in Italy. All their polyurethane inner seal disks have decomposed, even on the last few new valves. The lower one is a modern OMG substitute, made in Italy. It is a 16×1 vertical mount spigot back mounted sideways.

The cover panel must be removed, or a large hole cut, to allow access to the substitute valve.

There is no reserve capacity on the substitute, since the reserve tube is horizontal. A soft aluminum reserve tube that curves upward is optional, for an additional $15.  

 

 

 

---

A34. 16x1.5 female side mount

The upper one is an original Indian 16×1.5 side mount, made in Taiwan. All their inner seal disks have decomposed. The lower one is a modern Honda substitute, made in Taiwan. It is a 16×1.5 vertical mount spigot right mounted sideways.

The cover panel must be removed, or a large hole cut, to allow access to the substitute valve.

There is no reserve capacity on the substitute, since the reserve tube is horizontal. A soft aluminum reserve tube that curves upward is optional, for an additional $15.

  

 

---

A35. 16x1.5 female spigot right

This is a vertical mount valve for certain late 1960’s to early 1970’s Honda motorcycles and ATV’s.

Indian valve substitute: The threads fit an Indian 4-stroke moped. This valve would substitute for an Indian gas valve, but the cover panel would have to be left off. Or else you could not reach it because the knob is not facing outward anymore.

Honda Design: Note that the little arrow on the handle points opposite to the handle. So off is arrow left (handle right), on is arrow up (handle down), reserve is arrow down (handle up).

 

 

 

 

---

A36. 16x1.5 female spigot down

In most cases, spigot right (above) can substitute for spigot down. The valve can be aimed at any angle, so “right” can become “back”.

Honda Design: Note that the little arrow on the handle points opposite to the handle. So off is arrow left (handle right), on is arrow up (handle down), reserve is arrow down (handle up).
