Vintage Triumph 650 Black Diamond® valve/guide kit

Regular price $170.42 $0.00

 Kibblewhite Black Diamond™ valves are the best you can get for your Triumph motorcycle. These specially impregnated forged stainless valves have proven to have superior wear resistance and reduced friction than hard chrome or nickel plating. When used with C630 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.

Please note that C630 Bronze guides are undersized and must be finish honed, not reamed. Manganese Bronze guides may be reamed or honed to size.

Positive valve seals are optional but can be ordered with modified guides at no additional charge. When installed with the recommended .001" clearance a seal will not be necessary.

This set consists of 2 intake valves, 2 exhaust valves, and 4 valve guides.

If you are building a Triumph 650 twin or need to rebuild a head, these are the highest quality parts you can use. Oversize valves and guides are available for the same price. We ship worldwide and will answer any questions you may have that are not covered in the installation notes.
