cant get my shee to jet and ive tried about every size of main jet and havent changed my pilot have some on order now but the way i understand it your pilot jets are just for idle not mid range and my bike starts and idles great im going to try a 40 and 30 has a 50 now but i doubt that is going to make a difference. atv starts up great starts off great and as soon as you give it throttle it kind of bogs out i have athena big bore cylinders(392cc) bigbore cpis oversized radiator 34mm flatside mikunis k&npods. i have on order the pilots and a new needle jet it has a q2 but ordered p8s but im not sure thats going to be the problem because from 280 mains to 400 mains it didnt make a bit of difference. still did the exact same thing but when i have my fuel on off position it runs great hits the powerband and runs like its supose to but obviously you cant ride it like that. anyone have any input on what else it might be. the local shop kept telling me i need an adjustable timing plate but im pretty sure that shouldnt have anything to do with it because it runs right on off position. have 340 jets in now. thinks its close to the right mains. everythings clean and practically brand new. elavation 1400ft.
