Resistor caps & resistor spark plugs

I have ordered two NGK non-resistor caps for #'s 1 & 4, and modify existing #'s 2 & 3 NGK caps to non-resistor, to correctly run a set of NGK BR8EVX spark plugs with copper-core Dynatek 7mm wires.

Been running the BR8EVX spark plugs for a couple days with the resistor cap set, with no apparent negative effect on performance, but do anticipate a positive one when the caps are changed out in a week or so.

Any thoughts?

I don't think you'll notice a difference. The resistors are just for RF suppression.

Ignition Coils And Sparkplug Wire Choices
What came with the bike were ignition coils that even when new were marginal, add years of cooking under the tank in stop and go traffic, and the coils will fail when hot.

Replacement coils can be bought at www.z1enterprises.com . I believe "Emgo" is the brand. They also carry the popular Dyna 2.2 and 3 ohm coils along with replacement sparkplug wires.

Now, you have a choice on sparkplug wires:
1. Copper plug wires with no suppression caps(the best choice, will produce greater spark, but will produce audio noise on Radio's & T.V.'s)

2. Copper plug wires with suppression caps(a built in 5000 ohm resistor, that can some times fail, like what came with the bike).

3. Copper plug wires with no suppression caps, but using resistor plugs(the "R" in the plug number).

4. Suppression plug wires with no suppression caps.

NEVER use resistor plugs and suppression caps or suppression plug wires, as now there will be three (3) sources of resistance in the secondary loop of the ignition coils, possibly reducing the spark energy.

Another choice is the Accel 3 ohm coils, with a similar primary(small wire) electrical connection using ring terminals as the Dyna ignition coils. Whatever brand of coil you go with, make sure the primary wires will clear the mounting hardware, as the spacers will come really close, possibly causing an electrical short, blowing fuses. Some riders have replaced the metal spacers with Nylon or Plastic non conductive ones, reducing the chance of an electrical problem.

Less is more, unless you are planning on installing a TV and radio on your bike.

Beware the RFI interference can play tricks with digi multimeters, use an analouge one instead if no suppression is used.

I installed a Dynatek 2000 ignition and 3 ohm Mini-Coils a couple years ago, and tried the suppression wire/non-suppression caps and
B8ES plugs, but now have copper core wires with the suppression caps...which work excellent with non-R spark plugs, but I think the spark energy is diminished using R plugs with the setup.

Here's one #2 & 3 cap ready for conversion. I've read one suggestion to use a piece of solid brass rod in place of the resistor. Sounds good, but will something else work even better?

I doubt you could possibly feel any change in performance from res-res to res-nonres.

...which leaves 53% while riding.

At my grandpa's wake I told how he taught me how to handle weapons and to hunt at 14. He told me never shoot anything I wouldn't eat. If I shot a bird no matter what it was, he'd make me eat it. I believed him. Got some laughs.
The gun doesn't come out unless it's used. If one is too frightened to do that, it's better for them to call 911 and die. IMO

I have two of these ready to convert (for #2 & #3 spark plugs) to non-resistor, and prefer NGK's attachment design (to the plug wires and the plugs), over other cap styles available.

What would be the best thing (for conductivity) to use in place of the resistor?
