How to Tune and Modify Motorcycle Engine Management Systems

Over the past 15 years, motorcycle technology has changed more than in the previous century, and so have the tools with which we tune our bikes. No technical aspect has changed more than motorcycle engine management, thanks to massive leaps forward in computer technology. Today's fuel-injected bikes are far more efficient and powerful than the carbureted motorcycles of just a few years ago, but to many of us, especially those of us who cut our teeth on carbureted motorcycles, the complex electronic engine-management systems seem like esoteric voodoo. They're not. In reality, modern motorcycles are infinitely more tunable than carbureted bikes, and anyone can tune them—with a little guidance, of course.
