If your spark plug wires have zero (or close to zero) resistance, they also have zero (or close to zero) RFI suppression. While that may not be a big deal for some engines, for ECU controlled engines it'll wreak havoc.

Head over to the Magnecor website, it explains a lot. Especially how the direct current pulses in the ignition aren't as affected by resistance as those "low-resistance" wire sites would lead you to believe.

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.

You are a unicorn and I claim my $5.

How, exactly, does witnessing the bike idling 750 RPM faster than normal (remember, it's not adjustable, the ECU controls idle speed) for the first 5 minutes after installing the Pulstar plug (with no other changes to the bike), and immediately noticing that the rough idle the bike's experienced since 05 Jun 2011 (at 797.4 miles, I keep very detailed logs) was now completely gone, and this after I'd previously torn down the bike from the gas tank to the fuel injector, from the air cleaner to the intake valve in trying to track down the source of the rough idle... how exactly is that "Unicorn"?

Or perhaps you're referring to my going to a hotter coil, and eventually to a custom-built corona discharge system? That's because this bike is a rolling test platform, and I'll be experimenting with alternative fuels and lean lambda, so I'm going to need a hot spark to light the fire.

Pardon my skepticism, but the ECU delay getting back down to 'normal' 750 rpm idle just MIGHT be the ECU "re-learning" it's parameters after having been "reset" by a battery disconnection.

What about "the spark plug was the only change made on the bike" is making it hard for you to understand?

Do you disconnect the battery to put in a new spark plug? LOL

I've got some PulseStars but they've made no difference in running or economy.

The USArmy(*) tested those plugs when they FIRST came out back in late 1970's-early 1980's and they were no better than standard OEM plugs.

Impossible. Lou Camilli didn't work with pulsed power technology for Sandia Labs until 1987-1988, and the first iteration of the Pulstar technology (the precursor to the HotShot) didn't come out until 1994, and was only marketed to racers. The first patent for the Pulstar technology wasn't even filed until 1999. HotShots didn't come out until 2001. The first Pulstar plug wasn't released until 2006.

FYI, this is why I bought the plug, given that I'll be experimenting with alternative fuels and lean lambda:

I think if your ignition system is already doing well at lighting the fire, you likely won't show an improvement. For motorcycles, especially waste spark systems that are already on the edge due to increased compression and high RPMs, they apparently do.

I haven't been able to verify any MPG difference with the plug because two tankfuls ago, I changed out my rear gears for 15% taller gears, then one tankful ago I swapped in the Pulstar. But it does idle smooth now, and that can only be attributed to the Pulstar, given that it was the only change made immediately prior to the bike starting to idle smooth.
