So i got my extra bore honed and ported the cyl to match stage6 streetrace kit, have a 21mm oko,ct,pg long modded. Iridium pkug 7hix. Great bottom end, then just before the pipe hits it makes a weird burble sound and stutters, if mess with the throttle it will hit the pipe and rip, if i stay in the powerband its fine till i drop the rpms any ideas thanks

move the needle clip 1 up. that should lean it out a little to clear out that burble you got going on.
