BSA OUTER V. SPRING 68/69 A65
Outer valve spring for a BSA A65, listed in the 68/69 valve gear parts book entries.
This is the outer valve spring for a BSA A65, catalogued as 68-0930 and later renumbered 68-0475 (you may also see it listed as 68-930). It shows up in the parts book under the cylinder barrel and valve sections, so it's part of the valve gear that sits over the cylinder head, working alongside the inner spring to keep the valve seated and closed under load.

The description on file ties it to the 68/69 A65, so this is a BSA part, not a Triumph one, despite whatever shorthand it carries elsewhere in the catalog. If you're rebuilding a set of valve gear on an A65 head, this is the outer half of the pair - check what else the engine is fitted with before assuming every spring in the set matches this number.
We don't have a lot more detail on this one beyond what's in the parts book. If your bike's records show a different valve spring part number, give us a call and we'll sort out which one you actually need.
