Norton 750 / 850 Black Diamond valve kit (no guides)

Kibblewhite valves are the best you can get for your Norton motorcycle. Proven on the street, dirt, Bonneville Salt Flats, and race tracks everywhere, these are the legendary Black Diamond™ valves.

These forged stainless valves are specially impregnated which makes the stems incredibly hard and wear resistant. The reduced friction is also better than hard chrome or nickel plating. Nothing even comes close in terms of longevity.

When used with bronze guides and properly installed and finished, much tighter tolerances than factory can be used successfully for quieter operation, less friction, and much longer service life.

This kit includes 2) 1.500" intake valves and 2) 1.300" exhaust valves. These can be used on 750 and 850 heads.
