I am having trouble with the engine loosing power and missing while riding and I have t-shot to the aft cylinder loosing spark. This problem is intermittent, therefore making it hard to t-shoot. I do know that I have good plugs and connections at the spark plug lead. I have measured resistance values at the coil and "pulse coils" to be within specs per a local Kawasaki shop. I also know that if a pulse coil is bad I must remove the engine to change. I still want to eliminate the coil, and ignitor box before shotgunning a pulse coil. Any advise would help. Thank You.
