    Does it feel like fuel or electrical related?

    How does black spark plug = no compression?

    What is the compression reading an each cylinder?

    Have the carburetors been rebuilt?

    Does this engine have the original ignition system or the update kit installed?

    Get a compression tester and get some readings.

    Addressing the carbs and fuel lines would be my next step.

    unthread the spark plug ends on the wires,clip a 1/4-3/8 inch off them,rethread the ends back on.my sl1050 did the same thing on the mag cyl.

    Mine was missing at full throttle also. It ran great at 3/4 throttle, Then it lost fire. After doing the upgrade kit,turns out its the ignition coil.
