Reply To: I have a 2011 gt650r. I think it has a malfunctioning injector.
no code. sometimes ride the red fi light will come on . When that happens it will run normal then I’ll slow down to check code and red light go’s away so I can’t check the code. I also took the injectors out and cleaned them with carburetor cleaner and I used the battery and everything To get pull setting again it’s still kind of squirt but I don’t know if it’s dumping to much fuel or what
As long as it says F(i) not F(ONE) / F(1) on the dash you will be correct thinking the injectors will be suspicious then again, the fuel injection system also relies on the lambda sensors operating well so the ECU can meter the fuel properly and the ET sensor (engine temp sensor) so ECU decides to enrich the cylinder to cool it down a bit or not or when it gets to operating temps injectors work full time.
or the air sensors in the airbox to the throttle body (air vs fuel vs spark = happy motor)
Where you live in USA, see about a local wreckers to find a crashed 650, to buy injectors from cheap and test your theory that it is the injectors being faulty ?
