I have 2 carbs, one is currently on the engine and is different to the loose one. The loose one has some gubbins on it as shown, a little lever going to a small piston type of thing in a rubber sleeve, is it a trx carb? and if so why would the bits be removed? if it is a trx carb would it be better or worse than what is currently sitting on the engine? if its not from a trx does anyone know which bike its from?( i have looked on a schematic for a trx carb and cant see it)

Re: Carbs
Hmm...
The pics are very small and it's a hit hard to see what is what, but if you say the one on the bench has some kind of external linkage, then my guess would be that this carb is made by Keihin, while the on one the bike is made by Mikuni.
Mikuni carbs are standard for the TRX. They are a CV type carb which work well enough under all conditions are are fairly economical on fuel.
Keihin carbs, particularly their FCR version, are often used as after market go fast bits. They squirt fuel into the engine every time you twist the throttle (via the external linkage you described), they can be tuned to give more power than a CV equipped bike.
If you can link to bigger pics then I'm sure we can advise in more detail.

IIRC the Japanese bikes had fugs with acc pump on them...dicky wrote:Hmm...
