1970-72 Honda QA50 in Cowichan Bay, British Columbia

Rare 1970-72 Honda QA50. Numbers matching engine and frame. Restored a few years ago-about 10. Ran and drove well until one day it would not come out of gear? Probably needs transmission rebuild or?? Could be simple? These have a 2 speed semi automatic gear shifter and no clutch. The parts used were almost all honda parts that were availble ten years ago. Not available today!!! Only needs the gear box figured out and it is a very collectible bike- going up in value as it has very valuable parts and is numbers correct. The bike is complete. Cheers , NO TRADES, I am moving and need to sell some stuff otherwise I would never sell this.
