BSA B31 replica Gold Star short test ride to evaluate.

I thought this might be shown as a 'before' clip to compare with another run after I made adjustments by raising the carburettor needle from its lowest setting, to the middle one, ditching a rather restrictive looking bellmouth which had a gauze over the intake and also advancing the ignition timing a little, but I only got to ride the machine up and down the lane afterwards, as the owner wanted to head for home. I think and hope I managed to wake it up a little, but there is no video footage of an 'after' ride, unfortunately.
