raptor 350 jetting ? as well

Hey all. Got a great deal on a Raptor 350 the other day. Got the hint the guy I bought it from didn't have a clue on maintanence or anything other than how to turn it on. He put a Yoshi exhaust on it. Says he jetted it, questionable. Took the carb off of it today, badly needed a cleaning. Had a 134 main jet. Anybody running a 350 with a Yoshi full pipe that might know if this is the proper jet and if not which one should I be running? Tried calling Yoshi and Dynojet, didn't get very far.

Thanks, Chris.

try a 150, ther only 3 dollers at yamaha.
