Oh, I don't know about that. Ever tried a Pulstar plug? I'm running one now. Gotta say, I'm impressed by it.
First time I fired up with it installed, the engine idled about 750 RPM faster than normal, until the ECU dialed back the idle air bypass valve (idle speed on this bike is ECU controlled) after about 5 minutes. And the engine's got snap to it now that it didn't have with the iridium plug I'd been using (that only had 5200 miles on it)... I've read in a few places that single-iridium plugs don't work well with waste-spark systems, for some reason. The rough idle's gone, too... and I've previously torn down the entire bike from air filter to intake valve, from fuel tank to fuel injector looking for the reason for the rough idle.
As for large-diameter wires... they're the same as smaller-diameter wires, with more insulation. The wire I bought is rated to 80,000 volts. My new coil (not installed yet, but will be soon) is rated to 60,000 volts to replace the OEM 25,000 volt coil, but it's temporary until my electronics guy gets done building the corona discharge ignition system. Which is why I bought 10 mm wire in the first place, for the extra insulation.
