stEvEoPeN Posted June 23, 2010 Report Share Posted June 23, 2010 A few days ago I posted a topic 85% dailed in... So today I got to try out the new senario with my bike just a recall of whats done for aftermarket parts FMF sst Pipes Powercore2 siliencers k&n boisen pro series reeds air box lid on/snorkel off Boost bottle Jetting that I tryed today was 280 main 27.5 pilot stock needle air screw 2 turns/ tryed 1.5/1.0/2.5/3.0 elavation 2100ft/temp 70f The jetting seems pretty good according to the plugs, but the mid low rpm is bossigh, and sluggush of idle to WOT. If anybody has good input for the next step to figure this out other than the air screw, cause Ive tryed It would be really appreciated! I also tryed taken the air box lid right off, and it seems to have a louder more drawn out bog. If anything the plugs are a tiny bit lean, I know richer on stock needle never works for me, what about trying a dyno jet needle stage 2, if so what notch? or up the mains again?

GrMeyer Posted June 23, 2010 Report Share Posted June 23, 2010 The air screw is most effective between idle through 1/8 throttle. The pilot (slow) jet is most effective between 1/8 through 1/4 throttle. The jet needle is most effective between 1/4 through 3/4 throttle. The main jet is most effective between 3/4 through wide-open throttle. Quote Link to comment Share on other sites More sharing options...
