hello all my yzers, i have a 2002 yz426. i have put a fmf power bomb on with a fmf Q. i mostly ride between 1500 and 4000 feet in California. Ive been fighting the jetting forever it seems. right now i have a 42pilot stock needle 2nd from top and a 168main. now it feel good on top and mid but if i crack the throttle it will almost stall. if i roll it on smooth it dose OK. can you all help me?
