hi folks
ive got a strange problem with my bike in the 3/4 to full throttle range. Its strong at low openings and mid openings but splutters and surges under full or near full throttle. It also blued my dyna pipe really badly. ive always had this problem but it never bothered me because i rarely used to use more then 1/2 throttle, and since i cleaned my k&n filter the problem has worsened.
Before i would get this at about 1/2 throttle, but i raised my float height (because it was too low), went from a 165 main to a 177.5 main and moved the circlip up to the middle ring because the midrange went to rich, and cleaned out my carb with carb cleaner and compressed air.
ive also ran some carb cleaner in the fuel, current jets in sig
any suggestions before i move to yet another bigger main jet??
