BSA Gearchange lever
Gearchange lever for the footchange/kickstart assembly, part number 40-3073.
This is the gearchange lever, catalog number 40-3073, the pedal-and-arm assembly a rider works with their boot to shift gears. It shows up across a run of catalog listings tied to the gearbox and kickstart area, appearing in figures covering the gear cluster, footstart and footchange assembly, and the outer timing cover where the kickstart and footchange mechanisms live together.

The lever pivots on a shaft that connects through to the gearbox selector mechanism, so when the pedal gets pressed it moves the internal selector to change gears. Given how many different figure titles this part number turns up under, it's clearly a component that got referenced across several drawings of the same general area of the engine rather than one single view.
Our catalog record doesn't spell out which specific model or year this lever was fitted to beyond the multi-year span it appears across, so if you're matching this against your bike, give us a call and we'll confirm fitment before you order.
