16 Stock Diameter Valves + 16 Titanium Retainers

Set of 16 high performance valves for the GSXR1100 86-90 and Bandit GSF 1200 (Oil cooled, rocker arm). May work in other oil cooled suzuki 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. These valves have hardened valve tips so they can be used with the original rocker arm setup.

These valves are 28,5mm and 25mm (stock diameter).

16 Retainers made of best grade titanium (Grade 5).

The original retainers weight 8,6g and the titanium retainers weight 4,9g, 45% lighter.
 
These retainers have a smaller profile/height (0,5mm shorter) to allow for more valve lift without contact with oil seal and without requiring valve guide modifications.
 
Perfect for higher redline and more agressive camshafts.
