Hi Joe,
I have Taylor Spiro Pro wires and non resistor plugs N7YC at this point --- with a Trispark. The folks at Trispark confirmed that this setup would be OK. It seems to run well enough.

It's not easy to find the copper leads that Pazon requires.
None of the local Autoparts suppliers stocked copper core plug leads.
One supplier was able to order in a copper cored ignition wire kit for a common V8 Chev 350 or similar.

Try the Green Spark Plug Company - I bought this together with caps and terminals and was very happy:

I will only use copper leads. Carbon leads can break down with use, may be the reason for the different readings.
Pazon ignition, Champion N7yc plugs and resister caps. Bike runs beautifully.
Top engine tuner taught me never to use resister plugs and resister caps together.

Can't beat bell wire - glow in the dark too!

Anything I’ve seen sold as bell wire would be too delicate to use on an old Norton.

Obviously you are joking about ignition HT current making it heat up and glow, though. Nobody here is that out of touch with school physics!

Hi Ron,
No, but those original plug caps were not that nice. Just a rubber cover that went over the wire and metal contact clip. I like the caps that have a sheet metal thread that screws into the wire core.

I don't disagree, although I prefer the NGK ones. However, I like the original appearance of the Champion ones. I fit Accel clips to the solid wire core cable and just use the rubber cap from the Champion ones.

Sorry, I guess I forgot to add the ;)
 
If you used bell wire it would make for a nice "light show" in the dark...probably wouldn't be enough voltage left by the time it got to the plug to actually jump the gap... ;)

As far as secondary wire, I just used whatever Old Britts was selling at the time! ;) That was in 2008 and they're still on the bike! :)
 
I bought all the bits from lowbrow customs to make my own.
Modern wires with an old school look.
I'm running an analog boyer so I do not need any resistance.
Non resistor solid copper core wires with non resistor caps, non resistor NGK 1034, BP7ES plugs.
If I needed resistance for a different type of electronic ignition I'd simply use resistor plugs.

I’m sure “bell wire” is a terrible idea, but proper mains flexible cable, double insulated by PVC, has served me well as HT cable.
PVC really is most unwilling to conduct electricity.
 
Wire wound leads, used with boyer, tri spark ignition, podtronics then tri spark rectifier. No issues, or misfire no matter what I was using.

The reason that spark plug wires aren't insulated with PVC is that its temperature limit is only 85°C, which is easily exceeded under the hood of an auto. When it gets hot PVC will dry out and crack, and there goes your high voltage insulation. I see this all the time when testing electronics in a temperature oven (part of my job). We have to replace PVC ribbon cables in the test setup every year or so.

On a Commando, with the plug leads exposed to the air, the wires will probably never reach 85°C so you're probably OK.

Also, its UV resistance is poor, but that probably doesn't matter much on a bike either.

Do whatever works for ya.
 
I agree the original Champion plug caps look good. Mine all got hard and tossed. I would bet there are still some around.
 
I use the lowbrow woven type (black/yellow) on my 72 T120 and 68 A65 (mostly for looks) and a generic copper inner core/silicone outer) on the commando I use the old timey "Sparky" non resistor rubber caps in all use champion N4G in all my bikes they all have Pazon Surefire used Lucas Bumblebee wire previously but it got stiffer with age as opposed to.....

Well, I'll be dammed. I've never seen that before. I stand corrected.

But what I said about PVC's temp limit is true, trust me on that. I can't imagine why anyone would want it on a plug wire, other than maybe colors. Silicone wires are usually black or grey.

There is one level higher, called irradiated PVC that's rated for 105°C but you won't find that on mains wires.
 
I run a trispark, Lucas three phase alternator, Podtronics three phase RR, original 6v coils, Andover Norton wires and caps, and NGK BP7ES plugs. Runs like a scalded cat.
 
nobody's mentioned old school Packard 440 copper core (7mm) plug wires - is there a reason? I have some of this around the shop and ordered up a couple NGK (red) resistor caps. planned on making a couple leads to use with my champion N7YC's
 
As supplied by Trispark.

Seeing as the non-R plugs are being end of lifed, i will get some non-R caps and go to R plugs when the time comes.
