BSA HEAD GASKET B40 EARLY
Head gasket for the early BSA B40 single.
This is a head gasket for the early BSA B40. It's a BSA part, not a Triumph part, but Ed keeps a note on it since folks with mixed British-bike collections come through the door asking about it.

The head gasket seats between the cylinder head and barrel, sealing compression and keeping combustion gases where they belong. On these older single-cylinder BSA motors that seal matters a lot, since a blown or crushed gasket shows up fast as a loss of power or an oil weep at the head joint.
Our record on this one just confirms it's the early-type gasket for the B40 — it doesn't spell out anything more specific than that. If you're not sure whether your B40 is early or late spec, give us a call before you order so we get you the right one.
