Due to stringent emissions requirements, most modern day motorcycles arrive from the factory with lean air/fuel settings. Once a rider installs an aftermarket exhaust system or air filter, the engine flows more air, potentially leaning out the mixture even more than the stock settings. This can lead to conditions such as overheating, backfiring on deceleration, hesitation on acceleration, or an uneven idle. Unfortunately, most motorcyclists seem confused about how to correct lean air/fuel mixtures when it comes to fuel injected engines. Cobra's Fi2000 and Fi2000R digital fuel processors supply the solution. Think of this product as a digital jet kit, giving tuners and home mechanics the product needed to fine tune FI engines quickly, easily, and economically.
