I have been reading these forums for a couple years now and everybody seems to be running 300 main jets or more on there bikes and bigger pilots. I am running a dynojet kit needle on the forth clip, 280 main, and stock pilot, air screw out 2.5 turns. I have cool head 20cc domes, k&n,fmf's,boost bottle, and I ported it a little, mainly just sharpend tranfers, intake and polished the exaust side. It seems that my bike runs perfect and not one bike in my group of banshee's can touch me. Does each jet kit use different measurments for there mains, or would I pick up more power with bigger jets. When I say my bike runs good I mean I dont have the infamous banshee power band or anything, from the time I drop the clutch the bike is all there and pulls 6th no problem. Any two cents would be great, sorry bout the novel
