Anyone know what type of engine RCM was putting in their bikes before they went belly up? I thought it was a zonger, but am not sure. I want to look at punching it out to 140, but don't know if I can even get upgrades for it.

Also, where can I get brake pads for this pos?

It was a Zongshen with the 14mm wrist pin, we make a hc piston kit for it and the TB 141cc kit would fit but I believe but it has been discontinued so you will have to find someone that has it laying around if you wanted to do the 141.

Ive got an RCM motor built up with a 56mm piston and 63mm stroked crank. Many vendors sell top end upgrades, but you should update teh clutch springs and cam springs and cam to get the most from it. There are 57mm bolt on tops.

Brake pads...I think the OGM?

So those are my options?

will the 160 motor fit into that chassis?
