lets see how many types or #'s we can use on these am running BR9ES right now but am sure theres a better plug out there

I have always run BR9ES 's thought about maybe runnig Irridium plugs, or maybe Ev's. Rule of thumb is to run champion plugs in the us motors. I have never done this but others have. I think the plug number is RN57cc or some thing like that. The only thing that kept me from doing it is the plug is about an 1/8th inch longer than the NGK plug... Champiom Plugs are supposed to work better.

ive heard of that also champion plugs are suppose to be better well i guess its worth a try

I will be switching to them as well, they dont foul nearly as much and the gap seems much more true unlike NGK's where every plug is a mystery on what the gap is going to be.

I always used to use NGK's, now I'm running Champions.

wana hear a good one LOL i drove 3 hrs today to get to a race on lake it was -35 with wids blasting tents all over the place so i was there all day freezig my arse off the machine ran good all moning we tested and tuned ran a brand new set a plug after the second run i check my br9es to see my colors and 1 plug just broke in my hand with out doing anything so i change it for a older one but almost new run run run test test test everything went good this race was a 1 chance u lose yer out so i get to the line its running good right off the start i FOUL a other brand new br9es well we went home early thanks NGK LOL

That will happen in the cold, really sucks though that it happened when it did. I guess you should be thankful it was just a plug. What was your plug color like????

am running 1 coffee with 2 milks about and my plugs were hot wen it let go i just finished warming it up and ran fine i just ad bad luck i guess

Weird that you fouled them then, just out of queriosity was this a stainless looking plug or the on that is a kind of gold color. I have noticed last year especially that there seems to be 2 diffent plugs that come out from NGK, both solid state. The golder colored ones seem to foul way less often and have a more true gap. The silver ones however the gap is a mystery with every box you open and they seem to fould easily. Any one else have this prob or notice this???

Always use Champion spark plugs in Polaris motors!

Well i ran irradium ngk last to races and they work great never tried Champion tho but there that say out there for Sure

but i dont get it cause iv had that xc since new and to be honnest my causin as the same thing and between us both we fould 1 ngk plug and thats on 12000milles each sled so thats 24ooo milles and never fouled a plug i wana make sure u never foul a plug i ear alcohol is good for that

and thats wht am running ALcho yessss mmm the smell gotta love it that stincky polaris oil pueeeeee

yeah it stinks something fierce, thats why I run strickty AMS oil Interceptor. Worth the Switch

i run Blue Marble works and smells great

Heard good things about that oil. But I have never seen or ran it.

so far so good
