I need to know what kind of performance mods are available for a 2003 cbr 600 F4I. Im working on a SAE design competition and this will be the engine we will put in our race car. I would like to know about anything available, even turbo systems for this engine as I know nothing about these bikes. If you guys could show me links or give me ideas as to what I can do to get more power out of it that would be awesome. a little background could be needed on this, we are building a 600 CC go kart (essentially) capable of running in this sae competition. everything will be built from scratch each year. new frame, wheels, tires, brakes body, everything. I am responsible for the engine side of this project and I would like to find out anything I can to make this car fast. thanks
