Tighten up your clutch springs.The clutch plates might need a clean and light sand for extra grip.

You could get a piece of hard wood and wedge it between the bottom side of the drive sprocket and primary chain. As you tighten the cush drive nut, the sprocket will bit into the wood and prevent it from turning. All the best.

What model BSA is it?  I sell some clutch locking tools for the unit singles and pre-unit/unit twins.
