    kawasaki 650 sx spark

    Iīve rebuild the complete engine and after installing the engine it gives me only one spark when cranking the engine.

    Tried different spark plugs and checked the wires but only one spark and if i wait about 30 sec and crank again just one spark.

    Canīt figure it out .

    Sounds like the wrist lanyard isn't plugged in or the circuit is grounded. My Yamaha boat will do that if I remove the lanyard. It fires once to discharge the capacitor, that's it.

    No lanyard on a 650 sx , could be the stop switch now i think about it .
    Go check ,let you know.

    Edit: How stupid can a person be ,disconnected the stop switch wires and a clear spark appears , so the button has a problem.
    Thanks Steve45 you pointed me in the right direction.

    Sometimes the simplest things get overlooked.
