    I just replaced the engine in my 2009 F650GS twin. It runs like shit with the replacement engine.
    There was one plug I could not find where it would be plugged into. It’s on the wiring harness just above the plugs for the oil-pressure switch plug and coolant temperature sensor plug. Anyone have an idea what this plug may be for or is it unused??
    Thanks

    I have a 2009 and was in it to the point of having the camshafts on the workbench and do not recall a 3rd connector on that side of the engine...
    but have 2 thoughts:

    1) operation of the solenoid that vents the charcoal canister
    2) if there is enough wire to reach to the right side of the engine ...
    I think it could be for the CPS - cam position sensor ... and THAT would explain the crappy running ...

    Charcoal canister purge control would not (IMHO) cause shitty running ... AFAIK ...

    Disclaimer: I'm a dumb-ass ...

    @Reaver will testify to this ... maybe he'll chime in ;-)

    The cam position sensor is on the right side of the engine up front and I have that plugged in, and the plug type is different than the one on the cam sensor. The type of plug is like the two on the rear left of the engine for the oil pressure and coolant temperature.

    OP has a Canadian bike without the silly California evap crap. That plug is unused. My loose plug is taped to the harness with factory fabric tape. Without unplugging mine, any chance you mixed up some plugs?

    I see you went with the engine swap rather than fix your old one!

    Where did the engine come from? Same year etc? Describe how it runs like shit…

    I’m not sure if the charcoal canister is even on mine. There was nothing in the repair CD telling me to unplug it. Where would the canister be located?
    Running much better now though, seems like it took some time for the computer to gather some data(at least that’s my thinking anyways). Running pretty much normal.
    Would still like to know if the plug would be connected somewhere.

    Thanks Reaver that would be the plug for the charcoal canister then.
    Motor was bought on e-bay and came from Quebec. Out of a F650GS twin. Running good now, after some time it gradually got much smoother and does not stall.
    Thanks for the helpful replies folks.

    I was gonna suggest one of the hoses on the airbox, but if it is running better then awesome.
    My engine swap was easier than I thought it would be.
    Happy trails:wings

    Yes I agree 100%, not nearly as bad as I thought it was going to be. I’m going to fix up the engine I took out and if I have to swap again it will be even quicker next time.
