I just put a CT Racing pipe on and used the jetts that came with it. The stock main is 138 and pilot is 45. The biggest jet they sent was a 142 main and a 48 pilot. Sounds good but when I punch the throttle it hesitates for a second. I'm not to experienced with jetting. If altitude matters I'm from Jersey, temp is around 40 rite now. Any suggestions??? Thanks...
