No -- do not run resistor plugs.
The suppression wires already provide resistance.
Adding more resistance via R plugs will create too much resistance, which weakens spark quality.

It's okay to use the caps that come already attached to the Dyna plug wires, because there's no resistance in the built-in caps (resistance is only in the wires, with none in the caps). But, do not swap out the built-in caps for some other type of caps that have resistors inside the caps, because that would add more resistance to the resistor wires and thereby create too much resistance, which weakens spark quality.

The WORST scenario is resistor wires PLUS resistor caps PLUS resistor "R" plugs.

Use only one resistor component in the secondary circuits, being resistor wires OR resistor caps OR resistor plugs.

Good Fortune!

Unless you have a AM radio or concerned about the car 5 feet away from you, don't use them. Also, the end caps are made for those wires. In the past we have used silicon wires but didn't get better performance then the wire ones. Plus the connections weren't as good.They looked cool but that was all.

thanks Patton .that clears it up for me .i just got some b9es plugs and wondered if i brought the wrong ones .

Those are one step hotter plugs. B8ES is better for summer driving. If you're burning a small amount of oil, the 7's will work but with the high voltage coils you shouldn't have to use them.
Steve

been running B9ES plugs in my bike with the old ignition ,accel coils and stock kawasaki electronic .never had a problem with the heat range.so it should run good with the new DYNA set up.

i know the difference between a hot and cold plug. hot=7 cold=9

Just keep an eye on them. If they start going away, go colder. The engine will run cooler too.
Steve

never had to run a plug colder then a 9 if anybody has run a plug colder then a 9 let us know.and why.

I've always run 8's. Ran 7's while burning oil, tried BP7's, lasted longer between cleaning but 400 miles was too much. Valve job cured that problem. Maybe colder than 9 would be good for hotter climates, if you can get them.
