VALVE,BSA A65 EX.OVERSIZE
Oversize exhaust valve for the BSA A65 engine, listed under 68-0663/OS.
This is an exhaust valve, oversize, for the BSA A65 engine, listed under our number 68-0663/OS. It's a BSA part, not a Triumph one, so if you're cross-shopping this against a Triumph valve you'll want to double check you're on the right bike before ordering.

The oversize designation means it's meant for a head that's been reworked to take a valve larger than stock, typically at a rebuild when the seats or guides have been refreshed. It also carries an older reference number, 10-10104, marked no-longer-available in that form, so if your parts book shows that number this is the current equivalent.
We don't have much more written down on this one beyond what's here. Give us a call before you order if you want to confirm it matches what your head is set up for.
