Set of 8 high performance exhaust valves for the Kawasaki ZX7 ZXR750 H1 and H2 (1989 and 1990). Same size as the stock H2 valves and 1,5mm oversize compared to H1 valves. Valve compatible with both H1 and H2 engines.
 
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 24 mm (1,5mm oversize for H1).

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 intake valves also available.
