Question Iridium state of the art Spark Plugs for VN750

Does anyone know an Iridium Spark Plug part number for VN750's? or
where I can buy them online or locally?

Has anyone tried them?

Do they require Special Iridium type Plug Wires?

I searched the Vulcan Verses and found:

https://www.vn750.com/forum/showthrea...hlight=Iridium

There is no Iridium type plug wires but that same thread explains about replacing the wires. You can use solid core for the best spart but may cause problems with radios.

Iridium plugs? Why would you want to use those old things? I started using the Paladium plugs on all my vehicles. They have the built in nanoflux coil that increases the voltage at the tip. High enough output that they don't have a ground tip. Instead, they just arc to the nearest grounded metal surface. Setting a gap is no longer necessary.

yea, you could spend a lot of money on spark plugs and have the cool factor of saying you have plugs with exotic metals in them. And you may even gain a tiny bit of performance...but this is a non-computer controlled, carburated engine...get a set of proper temperature champion or autolite plugs and keep them clean and properly gapped and you'll be just fine.

Oh yeah? My $69 ($276 per set of 4) paladium plugs doubled my horsepower and brought my mpg up to 72. Beat that. They only need to be changed every three months. They'll pay for themselves in... well, that's not important.

By the way, do ya know any landfills that can take paladium? My garbage disposal engineer says that they can't because of the PCBs internal to the plug. Until then I guess I'll just hold onto the old ones. Or make things out of them and let my daughter play with them.

Sheesh...Autolite plugs as good as Paladium. You've gotta be kidding me!

Here's a place that has the cheaper gold/paladium for only $66 each:
http://www.toysport.com/catalog/part...99%20Turbo.htm

It's hard to find just the paladium plugs. Most are paladium/gold center electrode. It's even harder to find the version with the PCB core. Something about federal regulations of PCBs. I have to get mine from India or Thailand. I guess you can go to the website directly. It's made by matsu****a electric, through Panasonic Japan:

Cegodsey,

I thought with using the Paladium plugs in our bikes you have to switch over to the Tellurium pistons with Hastelloy "C7" (or maybe "X4") valves ?
The Matsu****a/Panasonic site said nothing about that ??!!

I think there was also something in there about rebuilding the muffler bearings, as the excessive heat build-up caused by the Tellurium can pretty much turn them into jello.

On a serious note....

I agree with Imnohero, stick with plugs the bike was made to use.
If anything, maybe upgrade the wires.

It was the C7 valves. But the heat in the muffler wasn't the only problem - if you recall, the piston sleeves had to be replaced as well. I remember when Julio took the first Tellurium-pistoned bike out for a ride, and the cylinder heads melted out from under him. What a surprised look on his face! Priceless. Actually, they reconfigured the paladium plugs so that it wasn't necessary to rebuild the engine with tellurium parts. (Besides, I'd rather go without mufflers than to replace those muffler bearings - what a job!)

On ANOTHER serious note, I usually just use NGK's. Unless it's in my car, then I'll get platinum tipped (because it says so in the manual, and the car doesn't run right without them). I've never had trouble with Champion plugs in a car, but I have a friend that has had trouble only with Champion plugs, and swears by Autolite. In any case, all the plug has to do is spark, and the fuel/air mixture does the rest. If you're worried about it, get higher powered coils so that you know you're getting a spark. Then it won't matter what plug you buy.
