Kit Overview:

RIVA Power Filter Flame Arrestor is installed. Screen-type element mounts directly onto opening at front of original flame arrestor case replacing the restrictive baffling system. Provides improved throttle response and all around performance gains.

RIVA Pro-Series EFI Control Unit is installed. Unit provides easy adjustment of fuel delivery to meet the needs of modified EFI motors. Plugs directly into factory wiring harness connectors for quick installation.

RIVA Cat Removal D-Plate is installed in place of restrictive catalytic converter increasing top-end speed while reducing under-hood operating temperatures and allowing the use of regular 2-stroke oils. A high quality stainless steel replica of the plate that is standard equipment on export model Yamaha watercraft without emission controls.

RIVA GP1300R Free Flow Exhaust Kit is installed. Kit replaces restrictive sound suppression system located between waterbox and hull exit reducing backpressure and engine operating temperatures.

Solas 14/20 DynaFly impeller is installed. This impeller is specifically designed for the Stage I GP1300R (`05 models). Billet Impeller Cone is included.

RIVA GPR Performance Ride Plate and Top-Loader Intake Grate are installed. Our ride plate and intake grate combo increase top speed and significantly enhance handling characteristics. Prop spin and cavitation found with the stock grate is greatly reduced along with the modified GPR's tendency to drop on its nose when the throttle is let off at high speeds.

RIVA GPR Pump Seal Kit is installed. Location specific molded inserts are siliconed in to the voids of the OE pump inlet shoe significantly reducing cavitation.

RIVA GPR Performance Trim Tabs are installed in place of original trim tabs. Designed to trim craft up for increased top speed and serve as a quick fix to unwanted proposing. Tabs are 2.5 inches longer than stock.

RIVA GPR Pro-Series Adjustable Sponsons are installed. Sponsons dramatically improve the handling of the GP1300R with a superior blade design and mounting angle. Sponson depth is adjustable to accommodate any riding style.

NOTE: Stage I Kit for competition use only.
