16 Oversized Valves + 16 Titanium Retainers by ABUSO

Set of 16 high performance valves and titanium retainers for the:

Kawasaki ZXR 750 ZX7 H1 H2 1989 + 1990

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.

Intake valves are 27,5mm (Stock H2 / 1,5mm oversize for H1) and Exhaust valves are 24mm (Stock H2 / 1,5mm oversize for H1).

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

The original retainers weight 7,9g and the titanium retainers weight 4,8g, 40% 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.
