Norton Spring, Valve, Outer
Outer valve spring for a 750/850 engine, part number 06-7822.
This is the outer valve spring, listed in the catalog under Engine: Valve Gear. Valve springs like this one work in pairs with an inner spring to close the valve after the cam and rocker have pushed it open, and the outer spring is the larger of the two, seated around the inner spring on the valve stem.

The manufacturer tag on this part points to Norton, and the catalog title turned up elsewhere confirms it's meant for a 750/850 engine, but our own records don't spell out which specific model that engine went into. If you're sourcing this for a rebuild, check it against your engine before ordering.
The catalog entry we have on this one is brief, showing a single appearance tied to 1975. Call the shop and we'll help confirm fitment before you order.
