How can you tell if your coils are firing on a 1993 kawasaki zx11 D model?

pull a spark plug one at a time . leave it attached to the plug wire and hold the plug right next to the frame or something that will make a good ground. be sure and hold the spark plug wire boot and not the plug itself or youll get a shock you wont soon forget. i even use pliers myself. as the plug is grounded to the frame crank the engine and look for a bright blue spark . if you have spark your coils are working . no spark could be coils, plug wires, etc
