250exers i need your help

[joe250]

What size main jets are you guys running with your exhaust? I have been working to get my big gun jetted right all night! It is a slip on also. Thanks.

no one knows anything?

I have the full big gun, and k&n, but not the jet kit. I'm using a 120 main and it runs great.

I have a modified exhaust and I am running a 115 main jet. I first tried a 120 but the plug was a little dark. Runs great on the 115!

when you open the carborator how do you know which one is the main jet? i dont really know anything about carborators and i need to put a larger jet in mine, im running lean. if any 1 could tell me what to do i would really appreciate it.
thanks
