'74 Eldo ignition wire set
« on: October 08, 2025, 07:41:18 PM »
Hey Gang, I need some suggestions for a plug and coil wire set. What is everyone using? I never thought it would be hard to fid something so common but I beat the internet up trying to locate something I could use. I saw MG Cycle Parts has bulk wire and all but no dist. cap boots. I; actually looking at VW air cool wire set to make work. Like I said in my Introduction post I'm totally new to Moto Guzzi so I do need help....thanks

They do have the plug caps (fake NGK type):

I buy bulk Belden plug wire at NAPA, terminals for the distributor and coil ends of the wires there as well. I use an inexpensive Accel tool to crimp the ends on.

Thanks Charlie, HUGE help. I was heading to NAPA tomorrow to check things out, what a cowinkiedink!. Is that "Summit" tool something that goes into a vise, vs pliers?

Yes, goes in a vise. Made by Accel, sold lots of places other than Summit.

I do not know the price of the tool that Charlie showed for crimping the spark plug wires. There are crimpers on the bay of fleas and the river site that have changeable jaws for plug wires, the little blue and red connectors and many more jaw sets. Reasonable priced and work well.

Yeah, I've been checking them out on Amazing and found one just like that one for $6, it chucks in a vise.

For $6 and Charlie approved, grab it!, especially if you already have some crimpers.

When I was recommissioning my ‘74 Cop Bike I got most all of the ignition lead supplies from Ton’s Performance. They really cover a lot of what you’ll need.

https://tonsperformance.com/

My local NAPA no longer stocks any copper core ignition wire, boots or cable ends.

K&L has picked up supplying a limited range of plug caps once produced by NGK.
NGK had stopped supplying plug caps a couple years ago.

I; actually looking at VW air cool wire set to make work. Like I said in my Introduction post I'm totally new to Moto Guzzi so I do need help....thanks
So, after striking out everywhere, short of making wires myself, I went into Mooresville, NC's racing district and over to Scott Performance Wires in Talbert Park. As I got off my Beemer, a man mat me out front and we had a nice chat about motorcycles and such. I asked him if he works here at Scott and he said, "well, I own the place"....what a cool guy. His name is Mark Vieau, pronounced (View). We went in, with wires and cap in hand, and he wrote up a work order and later that day they called and my resistor wires were ready. They weren't cheap but they are top of the line and they fit and work! The old girl starts like a champ now, one push and she sits and idles just fine. Thanks for everyone's help, it's greatly appreciated. This is a nice community to be in, thanks again.

Why resistor wires?
Because my riding buddy and I use two way communication and I use a GPS. My research tells me copper core will interfere with electronics. Why, are resistor wires voodoo for the loop frames?

Copper core wires on all my bikes, no interference with the GPS, but I don't use any sort of communication devices.

IMO, resistor wires aren't necessary on an old bike, that's all. Not "voodoo".

Need to ask for legit information, not being a smart ass.  Why are resistor caps (plug wire ends) like NGK necessary? 

The reason I ask is that I installed a full dyna ignition (coils & pickup) on my V7 Sport in the 90’s plus accel solid copper core wire and plain plug wire ends from the same generic accel kit at the same time.  I’ve never had any problems and the bike runs great.

Am I just lucky or ?.

The coil-condenser combination has an LC frequency which causes ringing in the circuit.  Resistors in the wires dampen the ringing.   Ringing causes RF noise, but can also put extra stress on the caps.
First you look where it should be, then you look where it might be, then you look where it won't be, then you look where it mustn't be.  And when you find it you discover "that's where it should have been."
