Hi Everyone, I'm new to the group. Thank you for having me. I just picked up a really cool bike on Marketplace. I'm hoping someone here can help me in finding the history on these bikes. From what I was able to find online it seems to be an early J1. It's a two stroke with no oil injection. It has 17" wheels. I haven't measured the piston but it's pretty small, it could very likely be 85cc. It's missing the left side cover and the chain guard other than that it seems to be complete. Any information would be great.
