    Weak spark

    I have a 1996 slx 780 with stock ignition. I went to start it today and it would not go. Pulled plugs and it has a weak spark, small. I tested stator wires by the manual and it seems to be ok. I even tried a different set of coils and cdi. All the same result. Battery is new. Kill is unpluged. Where to look???

    Plug wires....

    Test the spark plug boots and see if they are within spec.

    Then cut the plug wire back about 1/4" or so to reveal fresh, clean wire.

    Then rescrew the boots back on and zip tie them in place.

    Also make sure the ground wire connections are clean and tight.
