BSA Scavenge cover, crankcase
A crankcase scavenge cover, part number 67-1286, from the oil pump and gearbox sprocket area of the engine.
This is a scavenge cover for the crankcase, part number 67-1286. It shows up in the parts-book pages covering the oil pump, gearbox sprocket, and pressure release valve, which puts it down in the oil-return side of the engine rather than up top.

A scavenge cover like this one sits over the scavenge side of the oil pump housing, keeping the return-oil passage sealed as it draws oil back from the sump to the tank. It's a small part but it matters for keeping the return circuit tight - a bad seal here can wet-sump or let air into the return side.
