Hey guys I’m wondering what my bike is And also looking to see if there are any motor modifications that would be able to make the bike faster. I flat track and want to get this bike flying around the short track. Is there any aftermarket stuff for these bikes? And what about other motors that can fit within the frame. Obviously change motors mounts for them to fit
I can’t upload the pictures for some reason but the frame has a m with a square around it and says 47574-53 and the motor has 66bth0001 which is the 66 bth hummer. I would think it’s the first motor they made In production by the stamp? It has a twin spark plug head on it and a modified twin carb. Will post pictures when I figure out how to lol thanks guys
