Maybe to help pin it down, take a couple of small 12v bulbs and wire them across the primary connections at the coils, 1 to each coil. That way when the Pick-up coils, and ignitor is functioning correctly, you will see equal flashing on both of these test light bulbs. Wire up to the Handle bars so you can see them. If it is missing but both lights are flashing equally and the same as before the miss, then it is in the secondary ignition.

classic symptoms: bad coilhiroshima1320 wrote: Ok, I have an 82 kz1000 ltd. 20k on the odometer, new plugs, new plug caps, carbs cleaned thoroughly, several times, carb floats set, runs beautifully cold. Once it warms up it drops off cylinders 1&4. Barely idles, hardly accelerates. After it cools down, it runs fine again.

That was my original thought, but I kinda ruled it out, but I think maybe the coil I used was bad too.

Yeah, when my original coil failed I bought a "good used one" that failed almost immediately.hiroshima1320 wrote:

May result from insufficient valve clearances.
