KTT Valves and Guides
Inlet and exhaust valves manufactured in 21-4N with Tuftride coating. Both valves have a stem size of 0.312″ diameter. Valve guides to suit 0.312″ + 0.0005″, manufactured from a Colsibro equivalent (same material, different brand name).
Stem lengths are 108 mm for the exhaust and 111 mm for the inlet.
Valves have been manufactured with extra length to eliminate the need for valve caps. If you still require to use valve caps, you will need to grind them down to suit. All other dimensions to the original Velocette drawings.
Current stock: I have now sold out of the original valves and guides. I can get a further batch made if enough interest is shown — please get in touch.
