I am selling my Motobecane 50v. Its a 12v system so I know its later than a 78 but not sure of exact year because the main vin plate is missing. There is no title or Bill of Sale. It does run, but poorly. It slowly has gas seeping out of carb when it runs because gas passes past the rings due to them not being fully expanded. It has a new petcock, fuel line, and choke cable. The carb was just cleaned. The motor has spark and compression. All it needs is new rings and it should run fine. Email me at firstname.lastname@example.org w/ offers. I am looking to sell this to start my custom Mobylette AV33 project and 1912 Indian ...I need to buy a welder to start it.
