Bought a new 250x, had big problem with low RPM stutter/miss, was told to install J.D. jet kit. Put it in, bike ran great for first lap of the race, after bike got good and hot the low rpm stutter/miss returned,same as before, maybe even worse. This only happens at low rpm's, and under braking. Bike idles fine, good throttle response under no load. When riding especially in the slower sections(tight sections, we run Hare Scrambles) the bike surges with light to medium acceleration, runs like a raped ape when you can open it up. PLEASE HELP!!!! ANY INFO WOULD BE GREATLY APPRECIATED.
