Norton Valve Spring Heat Insulator (not fitted on inlet to RH1 cylinder head)

A valve spring heat insulator for the valve gear, not used on the inlet side of the RH1 cylinder head.

PN · NM23392

NM23392 is a valve spring heat insulator, part of the valve gear on the top end of the engine. The catalog note tells us it's not fitted on the inlet side of the RH1 cylinder head, which means this one has a specific application within a set rather than being a one-size-fits-all piece.
