| RIVA YAMAHA FX-SHO/FZ STAGE 2 ENGINE KIT |
| Our Stage 2 Engine Kit produces 260 horsepower @7,600 RPM utlizing stock ECU and fuel injectors. Kit delivers major acceleration and top speed and runs reliably on 91~93 Octane pump fuel. Installs easily and requires no internal engine modifications. |
| RIVA Performance Power Filter is installed. Kit replaces restrictive factory intake system delivering improved throttle response and top-speed. |
| RIVA E1 Supercharger Impeller is installed. This high performance replacement impeller delivers more horsepower and torque throughout the entire RPM range. Investment cast from extremely strong, lightweight proprietary aluminum and CNC machined to ensure exact tolerances. Sophisticated blade design is optimized aerodynamically & precision balanced to provide smooth operation. Installs easily into stock supercharger housing with no additional modifications required. Produces 13PSI of boost. |
| RIVA Performance Blow-Off Valve Kit is installed. Improves performance and reliabilty by relieving unwanted pressure during off-throttle operation reducing supercharger clutch wear and eliminating heat soak in discharge tube. |
| RIVA OEM Intercooler Upgrade Kit is installed. Billet aluminum spacers increase end tank capacity & water flow making stock intercooler dramatically more efficient increasing horsepower through reduced air exit temperatures. Features billet High Flow Pump Strainer that allows additional cooling lines to be added to intercooler without tapping into stock cooling system. |
| RIVA Intake Manifold Upgrade Kit is installed. Precision tapered billet sleeve directly replaces restricitve mesh element in intake manifold enabling engine to produce more horsepower through increased air flow and boost pressure (+1lb). |
| RIVA Fuel Pressure Regulator Kit is installed. Kit provides increased fuel pressure necessary to compliment RIVA Boost Clamp. Set at an optimal static 55PSI and configured for rising rate (@1:1 ratio) for our Stage 2 Kit, the unit 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 Boost Clamp is installed. Simple plug-in device controls communication between stock MAP sensor and stock ECU allowing you to run up to 17PSI of boost when used with our Fuel Pressure Regulator Kit. |
| 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. |
| RIVAEngine 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. |
