Set of 4 high performance intake valves for the Honda CB 750 Four SOHC up to year 1977 - air cooled engines. Does not work with 78+ cylinder heads.

Made of the best grade stainless steel (EV8 / 21-4N) commonly used in all high performance valves used for racing or high strung engines (N/A, turbo or nitrous), these are a great improvement over the standard valves not only in flow but also in strenght and heat resistance.

Valves are finished with durable black nitride coating to avoid stem wear and increase durability. All valves have hardened valve tips.

These valves are 34,0mm (2,0mm oversize).

These valves were designed to work with the original valve seat requiring only  usual valve seat machining.

Oversize valves are a great way of increasing cylinder head flow for modified and big bore engines.

Oversize exhaust valves also available.
