hey guys! I'm looking to build an MB- 80cc on a cruiser frame. I have one question: how much can these motors pull? I'm a heavy guy (350+) despite that, I'm in pretty good shape and have no difficulty peddling my bike around town (I have the bike rigged with heavy-duty components to support my big butt) I just want a motor 'cause I think they're really cool. So if anyone can give me some info, I'd be greatful.
