GP1200R 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 Kit is installed to increase airflow to motor. No internal carburetor modifications are performed. "Tamper Caps" are removed from high and low speed carburetor adjustment screws to optimize carb settings.
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 Cat Temp Sensor Chip is installedto prevent warning lights & beepers from activating when catalytic converter is removed.
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 Concord Impeller is installed. After extensive impeller testing we found the Solas 13/19 Concord to be the best all around impeller for the Stage II GP1200R's. Billet impeller nose cone included.
Anti-Cavitation Pump Cone is installed in place of stock pump cone on jet pump vein housing. Pump Cone significantly reduces cavitation due to its innovative design and asymmetrical shape that matches the angle of stock Yamaha pump nozzle.
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.
