Norton Valve Spring Outer
An outer valve spring for the valve gear assembly, cataloged from a 1973 listing.
PN · NM22838
NM22838 is a valve spring outer, part of the valve gear on the top end of the engine. Outer springs like this one sit alongside the inner spring on each valve, working together to close the valve after the cam and rocker push it open. Our catalog record for this one is thin - it shows up once, tied to a 1973 valve gear listing, without much else to go on.
