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.
Dyna grey coils will work well with the Dyna ign (Dyna S or 2000?). Most Dyna boxes also don't like solid leads, the EMF gets them all crosseyed, so you might have to switch to R leads when you run the new coils. Grey coils and R leads mated with a close .028 gap should blow the head off the thing. It's all good.
