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 leaks, resulting in decreased performance.

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

The kit includes a precision-machined aluminum block, designed with a Viton O-ring and a blocking cap for air intake.

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

Suitable for all Kawasaki Ultra models
