THE FI2000R O2 WORKS WITH OXYGEN-SENSOR -EQUIPPED EXHAUST SYSTEMS
The motorcycle engines utilizing oxygen sensors and closed-loop technology have very lean air/fuel mixture settings from the factory. These settings can limit power and make the engines run hotter than earlier models. The Fi2000R O2 digital fuel processor is designed to work with all exhaust systems (stock or aftermarket) equipped with oxygen sensors. It accurately adjusts the fuel-injected engine's air/fuel ratio in order for it to run properly. Best of all, it works much like a carburetor jet kit with adjustments similar to the air-mixture screw, the needle and clip positions and the main jet.
NOTE: California residents should purchase the Fi2000R ARB, which is approved for sale in California. ARB E.O. No. D-633-1. Note: ARB units for use in California are not adjustable.
