FZR Stage 2 Kit

This kit delivers big gains in performance (+8~9 mph) through easy to install, bolt-on engine, exhaust, and pump enhancements. Kit features our MaptunerX engine management system and will run on 91~93 octane pump fuel.

RIVA Performance Power Filter is installed. Kit replaces restrictive factory intake system delivering improved throttle response and top-speed.

RIVA 'B2' Supercharger Impeller is installed. This high performance replacement impeller delivers more horsepower and torque throughout the entire RPM range. Made from 7075 T651 billet aluminum, CNC machined to ensure exact tolerances and hard anodized to prevent corrosion. Installs easily into stock supercharger housing with no additional modifications required.

RIVA 'GEN-2' Power Cooler Kit is installed. Power Cooler is dramatically more efficient than original intercooler system delivering an increase of 20 peak horsepower with exit temperatures averaging 60?F cooler than stock. Features large, unrestricted core that exhibits minimal pressure loss compared to stock intercooler and integrated blow-off valve mount that will accept recommended RIVA/HKS Blow-Off Valve (sold separately). Blow-off Valve relieves unwanted pressure during off-throttle operation reducing supercharger clutch wear and eliminating heat soak in discharge tube.

RIVA Intake Manifold Uprade Kit is installed. Precision tapered billet sleeve directly replaces restrictive mesh element in intake manifold enabling engine to produce more horsepower through increased air flow and boost pressure (+1lb).

RIVA Fuel Pressure Regulator Kit are installed. Kit provides increased fuel pressure necessary to compliment RIVA Boost Clamp. Fuel Pressure Regulator Kit Set can be precisely adjusted to match the needs of your riding conditions. Plugs directly into original fuel system with OEM connectors and features a large 3/8" fuel return line that is routed through supplied rubber fuel tank cap. Includes integrated liquid-filled pressure gauge and billet Fuel Pressure Regulator Block-Off necessary for removal of stock fuel pressure regulator in fuel tank.

RIVA MaptunerX Yamaha Bundle is utilized to reflash original ECU. MaptunerX provides ability to quickly and easily load performance tunes directly into your stock ECU eliminating downtime that results from shipping for programming. Performance Tunes are calibrated to provide optimum fuel delivery, ignition timing and rev limit to compliment RIVA Racing Performance Kits. OEM dash display, engine diagnostics & engine safety functions are retained. MaptunerX features a full color, touch screen display, ability to restore stock tune settings and access to RIVA's complete tuning library and technical support.

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

RIVA Engine Cooling Upgrade Kit is installed. Kit delivers dramatically improved cooling efficiency to engine and oil cooler for increased reliability & performance. Greatly enhances water flow & pressure by replacing restrictive OEM water fittings with high-flow billet fittings and superior routing.

R&D Aquavein Intake Grate & RIVA Performance Ride Plate are installed. This 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.

RIVA Engine Breather Upgrade Kit is installed. Kit eliminates power-robbing crankcase emissions from your engine's air intake. Increases horsepower by removing the engine's requirement to burn relatively non-combustible oil. Also improves intercooler efficiency by preventing the oil sludge coating that lowers thermal efficiency.
