Set of 8 high  performance exhaust valves for the second generation Suzuki GSXR750 J/K 1988-89 – the short stroke "Slingshot" motors of 1988 and 1989.
These valves are for the DOT Head - also available in the 750 Katana from 1989 until 1998 and it is commonly used in big bore kits with the Bandit 1200 / GSXR1100 Bottom end with great results.
 
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 strength and heat resistance.
 
Valves are finished with durable black nitride coating to avoid stem wear and increase durability.
These valves have hardened valve tips (Stellite Tips) so they can be safely used with the original rocker arm setup.
 
Race Series is our new design that improves on our previous valves, with a 30º Back Cut to improve airflow and smooth the transition to the seat area as well as other improvements aimed at saving weight by optimizing valve dimensions.
 
These valves are 26,0 mm (1,0 mm oversize) and are designed to work with the original valve seat requiring only usual valve seat machining.
 
Oversize valves are a great way of increasing port flow for modified and big bore engines.
 
Oversize intake valves also available.
