Well, I have the 310 kit on the r now, but it has no midrange or topend pull. The lowend is very strong, but the mid and topend powerband is missing! The bike just sputters when it gets above 1/3 to 1/2 throttle. I've tried every main jet from 175 to 190 and still sputters. What the hell is going on with this thing?
