33 smoothbore main jet extensions and over filling issue.

[blackhammer]

Ive just picked up my first set of 33s for the 1150 i've put in my gsx1100, so apologies if these are simple queries. I did a fair bit of searching before starting a thread.

With the extensions, are they a standard thing on all 33s? Dose anyone know if they change jet performance? Or is their function purely to protect against surging etc?


Having some problems with one of the carbs over filling, float height set at 23mm and when i check needle seating with the bowl off it seems to be stopping flow ok. Is there any other way it could be over filling and getting out the front of the carb?

You might want to measure fuel level, not float height, to assure the float system is functioning properly.

Sorry, but I'm not familiar with the "jet extensions" you refer to. Sticking the jet further down into the fuel shouldn't have much effect, other than maybe making the system more fault tolerant of a low fuel level.

My 33's have the same thing, they are like that from Mikuni, http://www.jetsrus.com/carburetor/ca...iew_parts.html
