am not sure on the year but is 1[hidden information]. I am sure of the model (JX 50). Belong to my son in law since he was 12 years old and so he has had it for about 30 years. Stored inside, turns over, low compression, clutch seems to work, trans can be run through the gears. A web site called indiandirtbikeparts.com has NOS parts for these bikes and does not seem to be much they do not have. I would love to do this project but my list is to long already. A model like this was just shown on Pawn Stars and they paid $1500 before they spent the money to rebuild. Ask me questions and will do my best to answer. I am still working to get the year correct and will post when find out. Found out the year is 1971 and the model is different then thought and is JC54. This is great buy Parts worth more the the buy it now of $650.00.
