BSA Cotter, kickstart crank (.266" B.S.C.)
A .266 inch B.S.C. cotter pin that secures the kickstart crank to its shaft.
This is a cotter pin, the wedge-shaped pin that locks the kickstart crank onto its shaft. It's called out at .266 inch B.S.C. in the catalog, which tells you the taper and thread spec to match up when you're ordering. It shows up in both the gear cluster figure and the outer timing cover/kickstart/footchange figure, so it's tied to how the kickstart lever mates up with its shaft inside the timing cover area.

Cotters like this are simple but easy to get wrong if you grab the wrong size - too loose and the kickstart lever will work itself free on the shaft, too tight and you won't get it seated properly. Worth checking the fit against your existing crank and pin before assuming a direct swap.
