Need help with 03 yamaha raptor 660
Hey everyone I'm having an issue anything above 3/4 throttle. Bike runs great till I get to the high end..sounds like a struggle doesn't want to die but has the odd pop then all of a sudden it goes good above 3/4 throttle then starts over again. Quad only has k&n with full intake lid ,DG exhaust, pilot jet was changed from a 22.5 to a 25 and mains are still 140/145 and needles 2ND clip from the bottom was moved from the 3rd due to same issue... is this because the exhaust has too much flow for the main? Thus exhaust is stupid loud lol my neighbors already know it's me.
