sup guys sorry if this isnt alot of info. I rejetted my quad as to the recommendations of the hmf slip on "jetting". It sounds amazing but is way to rich and is causing the unburned gas to sometimes ignite in the exhaust pipe. looks cool, but it cant be good for the machine. Just wondering what i should try. Should i turn the airscrew out way more before i try to rejet. I'm gettin some 11.5 to 1 comp. wiesco pistons and some hotcam performance cams installled. I'm thinkin i'll just get those guys to rejet it right for me and just pay em. Any recommendations?

 

Just let them re-jet it for you. It will probably save you a lot of frustation, plus after the new cams and pistons are installed you will just have to re-jet anyway.

 

If your not comfortable jetting let them do it, otherwise as it sits I'd turn the air/fuel screws in a half turn then try it. mine are via thier recomendations also, but the screws needed turned back in to avoid the rich mixture
