I have a 66cc bike, and I've had nothing but trouble right from the start. I had head gasket problems, and when I replaced it, the person helping me didn't realize the engine was aluminum and stripped it. I had someone bore out and rethread it since I didn't know how, but when we were sliding the pistion back into the jug, one of the rings just broke for no reason. Well, we didn't think it would be such a problem, but it hardly puts out half the power it used to, even with the leaky head gasket! How do I increase power without spending more money I don't have trying to get a ring for it?
