BSA Kickstart quadrant stop
Kickstart quadrant stop for the inner timing cover / gearchange mechanism assembly.
This is the kickstart quadrant stop, a small part that lives inside the timing cover area, alongside the gearchange mechanism. It appears in the parts books under the INNER TIMING COVER and GEARCHANGE MECHANISM figures, which puts it right where the kickstart quadrant does its work returning the lever to rest after you swing it through.

The stop's job is straightforward: it limits the travel of the kickstart quadrant so the mechanism doesn't over-rotate and everything resets correctly for the next kick. It's not a part most people think about until it wears or goes missing and the kickstart starts feeling loose or off in its action.
Our catalog record ties this one to appearances spanning 1969 through 1972. If you're matching this against a parts diagram, cross-check against the gearchange mechanism assembly you've got in front of you before ordering, since small pins and stops like this one are easy to mix up between similar-looking assemblies.
