carb jetting

[ohiobanshee]

I just bought this bike it is 20 over 18cc domes in coolhead,32:1 premix race gas,28mm flatslide mikuni carbs,jetting is 270 main 30 pilots,fmf fattys,prodesign proflo kit with no lid,boost bottle,elevation is 600 ft. The problem is will load up and almost flood itself out after about 3 minutes of runtime.It starts on first kick and idles fine maby a little rich.If you try to ride it you can get about 50 feet then it starts flooding and wont rev.The carbs are clean and the needles are 5L in the middle clip. Any and all help appricated. BTW i have jetted a few banshees but this one is driving me nuts. ::

It sounds like you are in the ball park with a 270 as a main but you are way to rich on the pilot.

 

 

On flatside carbs the signal is much better thus you do not need as much fuel. I have a RZ shee and a shee both full mods and I run 20 pilots in each with no problem starting or on the low end.

 

FYI

Try a 27.5 pilot.

The 27.5 sound a little better than the 30............... :beer:
