GP1300R Stage 2 Kit
Note: All testing performed with 1/3 tank of fuel, trim neutral, sea level elevation, air temp 80-degrees F.
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 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.
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, significantly enhance handling characteristics and create better “hook up” in choppy water conditions. Prop spin and cavitation found with the stock grate is greatly reduced.
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.
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.
NOTE: RIVA Performance Kits intended for competition use only.
These are additional performance upgrade parts that can be purchased individually to improve the performance kit.
