I am using ngk after the stock champion fouled. No problems.

I also have changed my habits with not running for short periods of time. If I need it out of the garage for a moment I push it out unless I am going to leave it running for a while.

It is the short run times that are problematic more than the plug.

there was some other threads about a software update for the 2012's, but for some it has been a pain for there dealer to find it....try searching back through the 570 forum

 

I had mine flashed and it fixed the lean backfire but still had the stalling problem. It wasn't until I cleaned the spark arrestor (full of steel wool) did I stop the stalling problem. Yesterday was the first time I ever fouled a plug. I think it was because of what dutch said, not warming it up.

 

My original Champion fouled so I put in a NGK.

Seems to be doing good so far. Two trips to Pismo on the NGK.

i drove my 2013 for about 15 20 miles in two days then a week later went to go start it it wouldnt start tried everything then i decide to check the plug and it came out but left the threads in the cylinder head, got the threads out put a ngk in started right up, the second time starting it after the ngk it took a while and would stall and back fire, but once it finally started it was fine must of been all the fuel and starting fluid in there from trying to start it with the broken plug

 

I removed the champion plug for a NGK and just fouled the NGK in my 2013 LE. I went to advanced auto and bought another NGK iridium but they also had a autolight standard plug that cross referenced for 3 bucks...any reason why a standard plug wouldnt work anyone?? I havent tried it yet...

 

i was usiing the irduim plug but it kept fouling also so i called albi racing and talk to them over there and he sad the irduim doesnt get down inside the cylinder far enough so he gave me the ngk number they use on there 570s and 900s its a regular ext tip cooper plug it was about 1/8 or 1/4 inch longer..and the thing fired right up havent really riden it since other then in the street

i cant remember the number im sure someone knows on the forums but if not when i go to my dads where my rzr is stored ill get the number for you

 

Use NGK CR9EIX

 

Forgive me, but a CR9EIX sounds awfully COLD for that machine. Is that the right heat-range? The correct Iridium plug for my 800-S is an NGK BKR7EIX, which is considerably hotter. Just wondering...........

Cheers

At this point only time will tell what is working best for everyone. It's always fun for the first year or so when a completely new model comes out haha

 

I am using the NGK # CPR8EB-9. Seems to be working great. Got them off Amazon for $6.40 each. Just checked mine today when I did my service and the plug was almost new looking. It's been in for 6 months.

cr8e ngk now i also found the iridium plug being to short in the hole . the copper has slightly less reach than the factory plug but more than the iridium . i did foul out this weekend but it was minus 26 c and had splashed thru 8 inches of slush the day before
yea funny thing i had a spare ..... n for 4 bucks each have 2 more . it also idles better.

 

I have an Autolite, 2 different NGK plugs and the original Champion in my storage box that I swithched out when it was new. Ive already fouled an NGK iridium so maybe the champion will last....

 

Heat range is what adjust for fouling not the brand name lol

I would find out if their is a over rich condition that needs corrected with a software update (adjust your choke) or if they installed too cold of a heat range from the factory.

x2..

 

my machine has 2500 miles now with the champion plug and no issues.
plug does look ok. getting the reflash done soon, might switch to the ngk.

 

I've now fouled another NGK CR9EIX, so I put a stock Champion back in it. I purchased a NGK CPR8EB-9 to try , just haven't got around to it. I'm starting to think it doesn't matter , any plug that fits or cross references will foul eventually anyways.

My problem is I move it around in my garage a lot. It's a pain in the ass to push around. I've never heard of a four stroke that fouled so many plugs.

 

It really seems that short run times is a problem. Since I now won't even start it unless I am going to run it for more than 15 minutes I haven't had any issues with fouling. You could get some of those wheel dollies and then you can move it any direction.

500+ miles on stock plug and no problems. Maybe because it is set up so lean for CA standards.

 

Hey guys, I work at a Polaris dealership and we pull in and out 50 or so machines a day. The RZR 570, 900 and Ranger 900 will ALWAYS foul their plugs if you don't give them a chance to warm up. Its not just Polaris, the Kawasaki Teryx 4, and Can-Am's have the same issue too. For some reason the offroad world has yet to properly tune with EFI, just imagine if you fouled plugs on your car this often....

Any high performance engine will foul plugs if not properly warmed up, be it racing, speedboats, jetskis, snowmobiles, dirtbikes. Your car engine and systems are designed to be more reliable than high performance.

 

I still have the Original Champion Plug in My 570 @ 150 or so Miles I always either let it warm up or if I just need to move it out of the Garage I just push it in or out I did purchase another Champion Plug to carry as a spare & have no plans to switch brands I normaly run whatever brand plug that comes original equipment in everything I own & have had no issues so far.

 

So this is what I find odd.... I just bought a new 2012 570 and I read about the champion plug issues so without removing my plug I went and bough the NGK that everyone is talking about. I then got home and removed the plug in the machine and found a NGK CR9EIX. I thought stock they came with Champions? Unless my dealer replaced the plug for a reason that I do not know

 

In all likelihood, Polaris advertises for bids for XX thousand spark plugs meeting ABC specifications and buys from the lowest bidder. Sometimes it Champion, sometimes it's NGK.

 

I have now 1000+ miles on the stocker. No problems!

 

I'm not sure if my driving habits are different but I just have not had the issues reported here with my stock plug. I learned as a kid that if you were going to start a motor it had to run until it was warmed up. The other thing is that equipment responds to how it is treated, meaning if you ride it hard, then something will get over stressed and broken. Of course mine is mow a year old so, it will be replaced before the next ride.

 

99% of the time the fouled plugs are happening with the short run times.

I have just over 3000 miles on the stock champion. I have the plug out at 2000 miles and still looked new. I do always let my machine run for a bit every time I start it. I will change the plug on the weekend, but only because I do so once a year.

 

I finally changed my champion plug with a new one. Did not have a gapper but put plug in anyway. Machine seemed to run better with the old one. Going to buy a ngk CR9EIX plug today. Been reading that the tip doesn't go in as far. Is there a regular ngk that works ? CPR9EB-9 Isnt available here in Winnipeg, and no one has stock on the CPR8EB-9.

 

Hmmm.
