Well got a 79 kz1000 st (e) had some issues. Replaced the pick up coil with a Dyna S. Repalced the coils with Dyna's. New plug wires(the good ones). Ran great for a 5 mile ride and did the same thing. Just like somebody shut off the spark. Wait fires right up until it gets under load. $350 bucks and I'm nowhere. What else could be doing this? Plugs are new. All that's left is the regulator/rectifier. Could this be causing the trouble. I went through all my wiring and cleaned and didn't find any melted wires or signs of heat. I'm at wits end.
