Maybe your TPS?

I found this for diagnostic, ( electronic )

 

If you dont have access to a tuning tool you can start with wiring in a 12 volt light source.

There is a 6 pin connector behind your number plate. The red/white and blue/white are the wires to hook up a 12 volt light. Tap into those wires and start the bike. If the dfi system doesnt see any current issues the light will go off after 2 secs of the bike running. If you have a problem the light will stay on. From that point you would have to ground the yellow wire from the same 6 pin harness and it will give you codes using slow and fast flashes.

 

You the need to find the trouble code description and go from there.

 

Start there
