thanx i will check them, would that be from the boost bootle or was it maybe the major difference in the temp you think?

I have 260 jets in it now and i am not sure what position my needle is at. I never had a problem with it until now in the 3 yr's i have had it. And as far as air leaks go i am pretty sure that i don't but not sure on that one either. I went for a night ride this last tue night and that when it started and i haven't had the time to mess with it. Could it also have been the fact that i live in texas and it is normally hot as hell and it was about 25 degrees that night. I know that temp has to do with jetting but i am not sure that it would make it do that?

I recently put a DM boost bottle on my quad, It had FMF fatty 2 pipes and silencers and a stock air cleaner. My question is now it doesn't want to hold at a set RPM if i am crusing it will start to bog then the enging will rev back up and repeat and also back fires on the right pipe. If i am running through the gears at full go it runs like a beast with no problems. Any suggestions would be awesome. Gonna be at munster for the first time next week and really would like to be at 100%.
