2012 675 wont rev past 10K

hi guys.. sorry if this has been covered already..

i have a 2012 675.. it suddenly wont rev past 10K.. no code present.

i have had the dealer flash the ECU.. but that didnt help.
its been a track bike all its life...

about 4 years ago, it wouldnt start after the winter, i brought it in and they replaced the stator.

anyone ever hear of this ?

I think I read somewhere on this forums (at some point) that this issue can be caused by the clutch switch being bypassed or removed. Have you checked your clutch switch on the lever?

I am going to try that next track day.. im going to bypass the kstand switch and then the clutch switch..

Check your intake flapper if itís staying closed then itís likely the clutch switch.
ok..
where is the intake flapper? do i have to lift the tank?

so there is no way to bypass the clutch switch to determine if it is the problem ?

thanks for the info !!

Shine a light down the intake itís easy to see.

Yes you can bypass the clutch switch. But you need a toggle switch if you want to bypass it all the time as you have to actuate it for the ecu to work properly.

so in terms of diagnosis
can i just unplug it and jump it? what does the computer expect to see when the clutch is out? open or closed contacts?

It wants to see it closed to start and then open circuit to run.

Thereís no need to do that though. Just look down the intake and see if the flapper opens when you rev it. If it doesnít then itís most likely the clutch switch or the flap actuator or part of its operation.
