BSA INNER TIMING COV GSKT A65
Inner timing cover gasket for the BSA A65 twin, part number 71-1437.
This is the inner timing cover gasket for the BSA A65 twin, part number 71-1437. It seals the joint between the crankcase and the inner timing cover, on the same side of the engine that carries the kickstart and footchange gear. Our catalog record shows it appearing in the OUTER TIMING COVER — KICKSTART — FOOTCHANGE section for the 1971–1972 model years.

A gasket in this spot keeps engine oil from seeping out where the timing cover meets the crankcase, so it's the kind of part worth having on hand any time that cover comes off for work on the timing side. Because it's a paper or composite seal, it's not something you reuse once it's been compressed and cut loose.
The canonical description ties this specifically to the A65, which is a BSA model, not a Triumph — worth flagging since the shop trades mostly in Triumph stock. Check your parts book listing against 71-1437 before ordering to make sure it matches your particular timing cover setup.
