I recently purchased three project bikes. Two are Chinese dirt bikes that are pretty easy to figure out. The last is a vintage chopper that has been neglected BIG TIME!! I looked all over and cannot find a identifying tag. The only mini bike chopper I found that is a close match is a "Rare" Harley edition. I think this is a Chinese bike, but not sure. Please let me know if I should NOT pull this apart and put in a better motor. I'm thinking this is a 49cc motor? Pics of motor show the only clues I have. I have an extra 100cc engine that came with this mess but have no intentions on using. I plan on putting a bigger motor with electric start. My wife even likes this hot mess!!! Any help is greatly appreciated!! Thanks
