16 Oversized Valves + 16 Titanium Retainers by ABUSO

Set of 16 high performance valves and titanium retainers for the 1991/1992 Suzuki GSXR1100 M/N – these models have the oil cooled engine with valve shim adjustment, also know as shim style head.

Valves are made of the high strenght and temperature resistant stainless steel (EV8 / 21-4N) commonly used in all high performance valves 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 are 30,0mm (1,5 mm oversize) and 26mm (1,0 mm oversize).

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

The original retainers weight 9,2g and the titanium retainers weight 5,4g, 42% 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.
