EX GUIDE BRNZE GOLDSTAR
Bronze exhaust valve guide listed for the Gold Star, cross-referenced to BSA part B44M.
This is a bronze exhaust valve guide, and the description tied to it points to a Gold Star application rather than a Triumph twin. The alias listed alongside it, B44M, is a BSA designation, which lines up with that Gold Star reference - this looks like a BSA part that landed in our numbering under a Triumph-style PN rather than something that goes in a Triumph engine.

An exhaust guide like this sits in the cylinder head and locates the exhaust valve stem, letting it move up and down while carrying heat away from the valve into the head casting. Bronze is a common material choice for guides because it wears well against the valve stem and handles heat better than the surrounding cast iron or aluminum.
We don't have much more on file for this one beyond the basic listing, so if you're sourcing a guide for a Gold Star or B44M application, call the shop and we'll confirm the fitment and dimensions before you order.
