I have a coleman ct200ex only doing 26.3 mph. It has a tillison 212cc motor with a full stage 1 kit and the throttle stop screw fully out. . Im running the stock jackshaft with a 10 tooth centrifugal clutch and a 50 tooth rear sprocket. It accelerates really good and every time I take off the front tire tries to lift off the ground. Its an amazing acceleration then it just wont go any faster past 26.3mph. Thats what my speed app clocked it going. Any way I can make it go any faster? I want to get it to over 30mph.
