    Every now and then the left cylinder just cuts out... WHY? like its not getting spark. Ive change the fuel filter,sparks, etc.

    Some days it runs like a champ.

    Put an inline spark checking tool on it while you are working to determine whether or not you are indeed losing spark. If you are not losing spark then you likely have a valve that's hanging up. It's most likely not a valve out of adjustment if the condition is intermittent.

    Could be a coil, could be the valve's.

    check the connection at the coil. May have a loose wire.

    Replace the left side coil. Kawis are known for bad ignition coils.
