I hate to be the guy that asks about decel backfire/popping AGAIN, but I'm a confused now. I've got the idle running I think pretty good now. It seems to be right on 2 to 2 and 1/4 turns out. I read that at more than 2 turns you should go one jet size smaller. BUT I'm getting a lot of popping/backfiring on decel. Like almost constant. I've been reading around that that is from it being too lean and I should go UP on my pilot jet...? Maybe I need to raise the clip one position? I'm running a JD kit in a '04 YZ250F with starting settings per the little paper that came with the kit. Altitude is about 2700 feet. Temp is 60-70 (finally!) Stock header with Powercore/quietcore insert. I've also noticed it doesn't pop as much when the choke is on, but that makes the mixture more rich, right? So maybe I need to LOWER the clip one? Thanks for any help!
