RIVA Wastegate removal plate for Ultra

RIVA Racing Wastegate Delete Plate for Kawasaki Ultra 160LX / 250 / 260 / 300 / 310 Jet Skis

Reference: RK17090-WBO

This kit eliminates the factory relief valve which is prone to failure and leakage resulting in decreased performance.

The factory wastegate is designed to open at 16.9 psi, but often blows off at lower boost levels due to wear on the internal spring mechanism.

The kit includes a precision machined aluminum block-off, designed with a viton O-ring as well as a block-off cap for the air intake.

This is an essential upgrade at all modification levels to ensure optimum performance.

Fits all Kawasaki Ultra models
