So here's the deal: I put a 70cc airsal kit on my maxi yesterday. Everything went together well, 15mm bing had it idleing and performing well. I took it for a ride last night, alternating speeds, never really opening it up for too long, and the damn thing seized. I have the head and cylinder off now, but the piston is stuck to the wristpin, seems to be fused. This is my first experience with kitting a ped, so I may have done something screwy. As I said, it was running fine, then it got real loud and stopped. The piston wasn't stuck in the cylinder, still moved freely without the plug installed. Anyway, let me know your thoughts
