Great running project, top end was removed, barrel honed with new rings, valves removed and lapped in, oil pump removed and cleaned, carb cleaned and started with fresh petrol from a remote tank, the rest is left up to the next keeper, cafe racer, scrambler, bobber, or a good source of parts for your own restoration project. There are no documents, but frame and engine numbers are genuine and clear, frame number FB31 - - - -, engine number BB31 19699.
