This is the first time that I've posted. There's a guy around where I live that is selling an engine from a Honda ct70 along with the carb and everything. I was wondering if anybody has heard about moding the frame of a nc50 to fit the engine from the ct70. I figured it would be a pain in the ass, but I know that the frames for the ct70's are chain driven so it seems possible with a little welding. Thanks, Jon
