    01 genesis backfire

    My 01 genesis carbed of of a sudden started to backfire. Went to start it up before a ride and bang, blew off one of the exhaust clamps. ski was running fine before. I have a spare cdi I'm going to try from a good member on here. I quess I should open the stator cover to see how it looks.

    Well I popped my spare cdi in and the same thing happened. The stator and flywheel I have in there are only a month old and they were brand new. Anything else would cause that to happen?

    The obvious thing is the flywheel has sheared the woodruff key and slightly shifted the timing.

    Other possibilites;

    Spark plug wires crossed
    Spark plug wire(s) damaged internally, not to spec ohms
    Spark plug has gone bad internally, or plug gap is way too wide

    Hall effect sensor wires crossed
    Ignition coil primary wires crossed

    Loose wiring in grounding or battery feed to the CDI/coils/stator. Seems less likely to cause a backfire though.

    Thanks guys. I'll check the index and open the flywheel cover to see what's going on.
