BSA Rubber washer, 'Oddie' stud
A rubber cushioning washer for the 'Oddie' stud used on sidecover and related trim mounts.
This is a rubber washer that fits under an 'Oddie' stud, the kind of stud used to hold sidecovers and related trim in place. The catalog places it in the oil tank, sidecovers, silencer, and air cleaner figures, so it's doing mounting and cushioning duty around the sidecover and tank area rather than anything inside the engine itself.

The rubber washer sits between the metal fastener and the panel or bracket it's holding, keeping the sidecover from rattling against the stud and giving a bit of give so the panel doesn't crack under vibration. Appears across catalog listings from 1969 to 1970.
If you're replacing sidecover or air cleaner hardware and the old rubber washer has gone hard or crumbled, this is the part to swap in. Give the shop a call if you want to confirm which stud on your bike takes it before ordering.
