- High quality inlet valves manufactured by G & S Valves. - Following Head Sizes available (check your original) : 1.790". - Model 30M stem diameter : 5/16" valves were sometime fitted to late SOHC Manx engines and early DOHC engines. - Stem length: 4.875", left blank at end, so these can be cut to the same length as your original, and then the collet groove machined afterwards. This is the best way to ensure that you will have a valve the correct length for your cambox and spacing between cambox and head, particularly important if you are replacing a valve with a more obscure length. This type requires you undertake the final cutting to length yourself. If you wish us to cut the valve to length and machine the collet groove, please email seperately with order - expect £11 charge per valve, and turnaround time of at least 3 weeks. 09/09/12 - Note: 5/16" Valves currently out of stock.
