Stage 2 Performance Overview
RIVA Performance Power Filter 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.
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 / Boyesen Aluninum Reed Stuffer Kit into stock reed cages with stock reed petals. Stuffers increase fuel / air velocity through intake tract, resulting in increased throttle response and acceleration. "Tamper Caps" are removed from high and low speed carburetor adjustment screws to optimize carb settings. No internal carburetor modifications are performed.
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 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 DynaFly Impeller is installed. After extensive testing we found the 14/20 to be the best all around impeller for our Stage 2 Kit. Billet nose cone included.
RIVA Pump Seal Kit is installed. Location specific molded inserts are siliconed into the voids of the OE pump inlet shoe significantly reducing cavitation.
RIVA Top-Loader Intake Grate & Performance Ride Plate 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 FZ's tendency to drop on its nose when the throttle is let off at high speeds.
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 Pro-Series 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: We offer a modification service for your stock cylinder head that consists of decking and redesigning the combustion chambers. This modification will produce increased cylinder compression improving acceleration and mid-range pull. Please contact us for details.
