VALVE GUIDE,BSA 250/441/5
Valve guide for BSA 250, 441, and B50 singles, also listed under part number 10-10320.
This is a valve guide for BSA 250, 441, and B50 singles. The description in our records ties it specifically to that BSA lineup, not to any Triumph model, even though it's carried in our system under a Triumph-style part number. It's also cross-referenced under the number 10-10320, which may be the number you'll find if you're working from a different parts book.

A valve guide's job on any engine is straightforward: it's the bore in the cylinder head that the valve stem rides in, keeping the valve aligned as it opens and closes so it seats properly each time. Beyond that, we don't have much more detail on this one in our records.
Given the BSA-specific application noted in the description, give us a call before you order so we can confirm it matches what's on your bike.
