Triumph 6mm valve conversion kit


Black Diamond 6mm valve and guide kit
New from Kibblewhite is a complete 6mm valve conversion for Triumph 650 and 750 heads. This well engineered and ultra light kit uses single "beehive" springs with titanium retainers, light weight keepers, and Black Diamondâ„¢ valves with .2350" (6mm) stems with Viton seals. The guides are machined for the included Viton seals and do not need any additional machining for valve clearance, no matter how huge the cam lift is. If you are building a serious Triumph race engine or want to severely reduce the weight of your valve train, this once exotic conversion is now available off the shelf.

This set consists of 2pc 1.600" intake valves, 2pc 1.440" exhaust valves, and 4pc standard .5010" guides.

If you are building a Triumph 650 or 750 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.
