I just have had nothing but problems with my bike so far. I bought a built bike and already after one day of use had to replace the megneto coil and the cdi. That got it running. But the problem is that I cant go more than 10-15 miles and hour. This seems really slow for an 80cc motor. It sounds like it is just being governed but there is no govenor. Also the clutch is not working quite right in order to pedal without turning the motor over I have to pull the handle all the way to the handle bar and release it all the way for starting it. I have no instructions and I am a bit mechanical but these bikes are so new to me Im not sure what needs to be tuned to make it run right. Please help. Thanks
