The Fi2000R O2 version is intended for motorcycles with exhaust systems equipped with oxygen sensors and a closed-loop system. This unit allows the rider to retain the use of the closed loop system to ensure the motorcycle meets emission requirements, yet it will deliver the appropriate air/fuel ratio to the engine under load. As with all other units, this version comes preset and should require no further adjustments on the part of the person performing the installation.
     
       
    The Fi2000 comes preset for your specific make and model. It is also set for your bike equipped with an aftermarket exhaust system. This setting will enhance the performance of the entirely stock bike as well. If you add a high-flow air filter system, you might need to adjust your particular model. Each unit comes with detailed instructions showing you how to make those adjustments quickly and easily. You can also contact our customer service staff to help you adjust your Fi2000 should your specific set of parameters need it.
