Hi guys, I recently oversized my 500 88, 88mm to 89mm. I want to know if i need a bigger jet in the carb. IT was running good before the compression problem. Now It run good at low thru mid range but after that, it run like they missing gas or air. i just do the oversize, no more modif on it. I run FMF pipe and silencer, 38mm mikuni and radvalve with boysen proseries reeds. Run with the airbox no lid with KN filter.
Tks
