hey raptor guys.... my buddy has a 01 660 raptor. he has white brothers r4 pipe, and k&n. it was missing bad at about 3/4 throttle, then clears out. he should be running 85 mph, and side by side on my 400ex, i can stay right with him. he took it to a yamaha dealer, and they put SMALLER mains in 130 , 132. when we rode it at the shop. it seemed like it took out the miss, but it had no pull in top gears. i have rode others, and they try to shoot out from underneath you!!! everyone i race with, that has a rappy, said they jet pilot at 25 and mains at 150/155. anyone ever hear of going smaller like they did at the shop????? all input is appreciated! thanks
