Triumph 750 6mm valve stem conversion kit

Black Diamond 750 6mm valve and guide kit Kibblewhite engineered and manufactures a complete 6mm valve conversion for Triumph 750 twin heads. This well designed and ultra light kit uses single "beehive" springs with titanium retainers, light weight keepers, and Black Diamond™ valves with .2350" (6mm) stems with positive Viton seals. The guides are machined for the included 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 reduce the weight of your valve train, this once exotic conversion is now available off the shelf. We have extensively tested this kit both in racing and street applications, with only positive results.
