Okay, so new to the site, thought id see if you guys could help me out with this one. I have a 2003 raptor 660r. The carb is spotless. Can't find any air leaks. Cleaned wire going to coil. I have disabled both pb and reverse rev limiters. Pb by cutting the wires at the switch on the handle bars. Disabled the rev by cutting the red wire coming from the stator. It will start, and idle perfectly. But when I try to drive it will only rev up to about 1/3 throttle the sputter like the rev limiter is on but if I full choke it and pump the throttle quickly I can get it past the sputter point. Which leads me to believe its not electrical. I have tried adjusting the needle clip too. No dice. Just cannot figure this thing out.
