Re: 07 gsxr 750 cluster acting up and losing power
WRT your gear position- your gear position sensor sounds broken. Inspect it and replace it if needed.
As for speed being off- how many teeth on the front sprocket, and how many on the rear? it should be 17 and 45.
As for being jumpy and losing power- you need to provide more details. Explain when it happens and what happens.
