I have a 70cc 2-stroke and I took it down a bridge full throttle to see how fast it could go after a good 2 tank break in, about 100-120 miles. It was going fine until I got to the bottom of the bridge. I let off of the throttle a little bit and the engine locked up on me. I had to move the wheel back and forth a few times to get it to free up. So I took the top off of the motor and noticed that a very small piece of what looked to be the piston had chipped off. I was wondering if this very small piece could affect the compression of the piston. My guess is that I need either a new piston, or a whole new motor.
Also, I noticed that the ends of the wires coming from the motor had burned holes in themselves. Not sure how this happened. If anyone knows what happened or has any tips, that would be great.
