EX VALVE BSA A65 UK
Exhaust valve for the BSA A65 650 twin-cylinder engine.
This is an exhaust valve for the BSA A65 650 twin, not a Triumph part despite how it's filed in some of our records. It's a straightforward engine internal that sits in the cylinder head, opening to let spent gases out through the exhaust port on each firing stroke.

The catalog listing here is brief, just the part number and a description confirming it's the exhaust valve for the A65 UK-spec engine. We don't have more detail on file beyond that, so if you're matching this against a specific head or an old parts book reference, give us a call and we'll confirm before you order.
Worth keeping a spare on hand if you're doing head work on one of these motors, since exhaust valves take the brunt of the heat and are a normal wear item on any air-cooled twin of this era.
