This system is not compatible with OBD2, it has its own diagnosis system. Car manufactures were legislated into coming up with a universal diagnosis system (OBD2) Unfortunately this legislation does not apply to motorcycles. They all have different diagnostic systems. The shop manual explains how to go into diagnostics mode, you don't need any external device, the info comes up on your display. With this info and the shop manual you can diagnose your bike's EFI system.
