    They are the same unit for both bikes so it will be a bolt on affair.

    Kindly keep everything to do with your 650 in one thread.

    I'm still awaiting photos so I can have a look at what you're describing.

    Barring that, something is bent, or a hole was wallered out and the plates got misaligned.

    the rotor should never touch the coils, ever. change the plate, coils and all. rotate the engine with a wrench and go slow to make sure the rotor doesn't hit the coils.
    pictures would be good because what you describe should never happen

    If you have them, give it a try.
    Electrically they should work

    Use the tci for the motor in it .
    A different one will fire it but the ignition advance might be wrong

    Well I'm glad that it was a messed up little part and not a messed up big part.
