That reminds me.. what is everyone running for coils on their KZ? I've got the Dyna ignition and I was all set to buy some proper coils when I checked my stock ones, which are 2.4 ohm. Somehow I thought the stock ones were > 3 ohm.
Anyways, chasing a rather wimpy idle strength and am pretty sure it is spark quality related. Running copper wires with resistor plugs gapped to 0.028". Some have said the stock coils with a Dyna ignition can't really do well beyond 0.020" gap, and recommend the Dyna grey coils. I will probably reduce the gap and experiment a little. Other than not having enough tractor pull at idle it runs pretty strong.
