RIVA Kawasaki Ultra 310/300/260/250 Wastegate Block-off Kit

This kit eliminates the factory wastegate that is prone to fail and leak boost resulting in decreased performance. The factory wastegate is designed to open at 16.9psi, but often vents at lower boost levels due to wear on the internal spring mechanism. Kit includes precision machined billet aluminum block-off engineered with a viton o-ring seal along with a block-off cap for air intake. This is an essential upgrade at all levels of modification to ensure peak performance. 

Fits all Kawasaki Ultra 310/300/260/250 models.
