I have an old project trail bike called a Yamaha Chappy. It is a 50cc, red, with manual pedals. It does not run but I am working on that. I think it is carburetor issues. I think it is from the early 80s but I have no title for it. Please see the attached picture showing the partially worn VIN and engraved frame number. The engine block also has the same number (2U7 061190). I contacted West Coast Yamaha and the best we came up with for the VIN is JYA2U7004CA061190. I need this for parts and I want to street license it. Thanks for any help.
