BSA Shim — engine sprocket (·015")
A .015 inch shim for the engine sprocket area of the crankcase, used to set spacing or end float.
This is a .015 inch shim used at the engine sprocket on the crankcase, per the parts book entry filed under the CRANKCASE — GENERATOR figure. Shims like this get stacked or swapped to set end float or spacing on the sprocket shaft, and the .015 thickness gives a precise adjustment increment without having to rely on a single fixed-thickness part.

The catalog only shows this one appearance, tied to 1972, so we don't have a broader run of years or models to point to. If you're chasing shims for an engine sprocket job, best to bring the shaft and existing stack to the counter so we can check what you've actually got before ordering.
