Question; I have a XR200 motor in a XL125 frame set up for flat track. My problem is: My cousin had the motor worked on in Calif. Bored, cam, head work carb work and whatever else. The motor is strong and fast, but, it wants to surge in the turns. Down the straights its very fast. Its not missing, just lunges and surges. Ive changed the gearing, jets and etc, but , it still is uneven in the turns. Stumped, any suggestions?
