Cause the sleds CDI is made to run with them. The spark plug wires cap is a 5000 ohm resistor, just like your Cat's wires/caps were, that's the reason it didn't mess with TV's (TVI)) interference.

If you were seeing better starts, better performance, and fuel mileage with the non-resistor plugs then you had other issues with your sleds.

 

I guess I just can't imagine all the sleds, chainsaws, snowblowers and other 2 strokes that I have ran with this type of spark plug in, have had other issues that a non resistor plug, fixed.
I've installed these plugs on dozens of customers sleds and have had NO neg. feed back and all showed improved performance, especially in very cold starting conditions. Just trying to share what I thought is a good cheap performance enhancer.

 

Resisitor plugs do NOT take away any performance from the engine, or increase fuel mileage, dyno-testing has varified this..

 

Gee Don, I'm sure your dyno results will show that but I've seen many dyno gains that never showed up when the track hits the snow!!!! Maybe just try a set on a -15 morning and see if you get an easier start. I don't believe the spark plug really comes into play when trying to make power on the dyno. I thought it was compression, fuel and its mixture, timing, resonance from the pipes, ect. I don't believe a resistor and non resistor plug will show or not show power gains but I believe there is better performance on the trail to be had with the non resistor type.

 

My sleds start first pull almost everytime.


You'de be mistaken then as all of this has been tested by others and myself in the 45 years I've ran a sled shop/machine shop. If it were a performance gain/fuel saver don't think for a moment that everyone would be running them? My performance and service manuals state very clearly that damage to the CDI will occur if non-resistor plugs are used, wonder why that is, and what about the 5000 ohm resistor caps on the wires, you remove those too?

Some of the older CDI's were unaffected by the non-resistor plugs usage.

 

No I do not even use the stock wires. For the last two years I have been running the Nology, hot wires with the built in capacitors. They come with a solid silver, non resistor plug that they make for there wires. Thats where I came up with the Idea of using a regular non resistor instead of there high dollar silver ones.
I have had NO cdi failures with these plugs. I had problems with a cat 580 EFI, the non resistor messes up the injectors some how, but I'm not sure what the exact failure is or why it occurs.
This is great stuff, as I know very little about the Polaris electronic system and will take your word about cdi failure, BUT, I have installed these plugs on quite a few 500 Indy's with no draw backs as of yet and on a shit load of Cats with no problems.
My last Cat, a carbed 02 ZR 900 ran these plugs for five years. Now I don't know if i should run them in this XCR?????? Can you please post the service manual page that explains this??

 

I can't say for sure how sled engines hold up, but in the quest for a better, hotter spark, I put non-resistor plugs, copper strand wires and solid wire Mallory boots on my Yamaha V-max motorcycle. Guess what? The CDI box went out after a few months of riding, new they're over $400. I'm not taking any chances out in the woods out in the toolies.

 

Read paragraphs 4-7.Resistor Plugs, Wires, and Related Issues

 

Well Don this is a very interesting read and I learned from this. I can only conclude that the 5000 ohm cap has protected the electronic systems on the sleds that i have used these non resistor plugs on. I guess you can see the gain I have achieved by reading paragraph 8, with the greater spark associated with easier starts and better performance. I will test my theory on my XCR this winter AND will carry a spare cdi just in case. The fact that none of the sleds I have installed these plugs in have had no cdi failure shows me there is hope and better performance to be had with them.
Do you have any Idea how far away the cdi has to be from the ignition source to overcome this interference?
Now I understand why my EFI screwed up but it never ruined and electronic parts just would not run very good and flashed an efi code.
I thank you for your knowledge and the sharing of it. Myself and three of my buddies are starting a plan to attend the Moose Lk. deal. Do you think it would be ok to set up a large tent on the lake and camp out????

 

The National Forest Wardens will never allow it, there is Winter Camping at the primative Moose Lake campgrounds.

I believe paragraph 8 was talking about larger plug gaps not the lack of resistors.

Read toward the bottom of paragraph 2 on surplus voltage.

 

I guess I forgot to mention the part about opening the gap to .045 as those silver core plugs have. Do you have a contact number for the primitive camp ground? We will be taking our hunting camp down soon and will just keep everything at hand and not pack it away. Would this be close to the track and refreshments??? I have four XCRs and there riders lined up as of today but are trying to recruit a couple more to lessen the individual travel cost. I'm already getting excited about this outing.

 

I know they had Winter Camping although this link says no, call them to find out. It's about 1-1/2 miles to the food and track.

Great link Don.

KDR, another thing to realize about the 1996 and later TRIPLE, TRIPLE XCR ignition system versus most others is it fires "sequentially" rather that batch or simultaneously as nearly all other 2-strokes do. So, don't cross any plug wires.

This was done to increase the available spark voltage and is one reason the XCR 800 runs as good or better than most big triples. Polaris really maximized this engine!!!

Ever wonder why a Mach Z Skidoo needs a .018" plug gap?:bc:

 

I did not know this, I thought it was the same wasted spark system that they all use. I'm trying in ingest as much as I can about Polaris's. I know they run better then most all other big triples and thats the reason I switched from Cats. Be patient if i show my ignorance from time to time, but i learn fast.
