Hi Steve,
Your reply, just before mine, was not there when I initially started to reply. (Sometimes I get distracted in the middle of a reply and have to come back to it later.) I thought you were talking about another standard KZ.
With the ECU, Kawasaki may have indeed had a reason to do what they did. Perhaps with the extra cylinder pressure from the turbo, which effectively increases the spark's required voltage, there is more interference, so Kawasaki put in the extra resistive elements in the spark path. Regardless, if Kaw made it that way, it should work. It could get pricey to take a chance and see if the ECU can take excess EMI pulses.
My buddies RD400, with solid wires and no resistors, has fried more than one multimeter. Two strokes (in addition to turbo bikes, and high-compression bikes) can also have an extra high voltage requirement at the plug due to oil fouling. That's why they sometimes do better with CDI.
