I was reading through another thread and saw that Iridium plugs have built-in resistance an one doesn't need the resistance plug caps...is that right? What is the result of having all of that resistance?

I always use iridium plugs and always remove the resistors in the caps. My own view of it is why impede current actually reaching the plugs? I want as much current hitting the plug as possible, so that the spark is better. Doubling up on resistors is pointless.....XS1100F 1980 European model. Standard. Dyna coils. Iridium plugs.

LoHo- I read some great threads on here with regard to the very question u asked. I ended-up going to Home Depot and bought a foot of 8 gauge wire and cut it to size.1979 XS1100F

Well I certainly am not an electrical giant so I am not sure of the reason for resistors ahead of (or in) the plugs. Is it to keep your neighbor's TV from blinking when you start up? I don't know. But once I got rid of the stock coils with the iffy wires and opted for aftermarket Dyna coils, I have been using ACCEL 8.8mm stainless wires with great success. With non-restrictor type plugs, all secondary voltage goes straight to the plugs. Plus they are yellow which gives a little splash of color on top of the motor.
Now that I think of it, look at the 2nd bike from the right above....that's mine and you can see them.Mike Giroir

The resistors are to to suppress radio frequency interference.Originally posted by TADracer View Post
It is actually possible to get fined if you knowingly produce radio frequency interference. If you had a neighbor around you that was a amateur radio operator and you were running your bike for whatever reason and they experienced disruptions and asked you to fix the problem, you actually do have to fix it. If you don't they could file a complaint with the FCC and on and on.Nathan

I run the Irridium plugs, which have the resistor built into them. I have noticed though, I have trouble with my keychain garage door opener while my bike is running. Some days, I have to kill the engine in the driveway to open the door.1980 XS850SG - Sold

Makes sense....but I live in new Orleans! There are only maybe three guys that know what an amateur radio is.Originally posted by natemoen View Post

Yeah, but get someone like me visiting and trying to use a radio and you MAY get a visit from the feds!but I live in new Orleans! There are only maybe three guys that know what an amateur radio is. We would probably just settle it with some crawfish and beer.
But then, the noise from a non resister engine will kill the AM radio signal, and most of us HAM's really don't care!
The resistors in the plugs will keep the noise down, and solid wires will keep the bike running well.Ray Matteis

So, to sum up, if I run the Iridium plugs with non-resistor plug caps, I'm still golden?"Time is the greatest teacher; unfortunately, it kills all of its students."Comment

That's what has been on the '79 for about 20K miles....

Ur not "still" golden, you're golden. Irridium plugs already have resistors, so running irridium plugs with resistor caps is redundant, and not well to do.Originally posted by LoHo View Post1979 XS1100F
