im currently trying to jet my bike to match the 03 636 header. i have been having blipping or pulsing happen around 4k at 1/8 throttle.
this was happening slightly after i shimmed the needles, but now that i have gone to the jet kit it has gottin even worse. and i cant figure out what is cuasing it. i have also moved up main jet sizes.
top end full throttle is excellent with the bigger jet size


my questions are...
does going up in main jet size effect mid-range or just top end.
should i try to lower the needle clip to get a leaner mid range?
also any other suggestion would help.
thanks,
ryan
