Bike recently began doing this. When I press the starter button, the fuel injectors don't seem to turn on, nor does the fuel injection light come on. The bike does not crank over, there is only a whining/whirring sound coming from the starter motor. I took off the case where the starting gear is and it does spin it, so my guess is that the starter motor is not the issue however I'm not sure. Definitely not a battery issue, tested the battery and it's fine. The bike will run if kickstarted. Anyone got any ideas how to diagnose this? Thanks.

Sounds like sprag clutch (aka. freewheel) failure :-

But you'll need a special 'puller' tool to get this bastard (aka. Flywheel/Rotor) off :-

Good luck and have fun.
