Have you told your dealer about this? Your plugs should last 3000miles... not 3000seconds.

 

Ya mine has been great no fouling plugs!

 

I've put over 720 miles on my '12 IQ Shift 600 with no problems in the month.

My dealer did say you don't want to idle it all day as it could foul the plugs ironically.

Now I believe your 600 has the new 2 injector set up vs. the 4 on the '12 and earlier CFI's?

 

My IQ fouled plugs like crazy, ended up being bad injectors

I posted a thread earlier about my machine loading up and backfiring not a loud boom but like a swirling ignition sound somewhere between the motor and the tip of the exhaust . Wondering if you have ever heard this noise ? I pulled the plugs on my sled yesterday and they are black as black can be Installed brand new ones and am taking it to the dealer along with the old plugs to show him ASAP but I guess I would rather have a rich running sled then a lean one I dunno

My indy 600 backfired twice on me my last ride

 

i fouled 1 plug in 800 miles and always let it warm to 100 never had a problem after changing origional.

 

Hmmm my dealer said 70 •f was sufficient to start rolling is that to early do you think ? I never hit it out in till at least the 90 mark so at 70 I usually do the warm up lap around the yard with quarter throttle blurps is that bad ?

Dealer is right. Waiting for 100 before moving is a waste of time. Last weekend when it was -13 when we started out, I would have been there idling for very long time gettng to 100. From just over 70 I just go very low throttle for the first few minutes and its fine. Never fouled a plug in over 1000 miles now. Also, never fouled one on my '06 600 carbed sled in 4000 miles either. That one didn't even have a temp guage.

 

These cfi machines dont like any type of throttle movement until they are warm. In the first 100 miles with mine it fouled 4 plugs because I disregarded the temp guage. Last 600 miles 0 plugs but let it get to 100 no matter how hard far ahead the rest of the group is ahead of you. Gotta let her idle after long wot runs too to get the egt down before you shut it off too.

 

I'm gonna start letting mine warm up to 100 from now on too

Not many miles on my Indy yet. No fouled plugs yet an Im not sure what to do if it did.:blink: Ive had my 600 xc 13 yrs and its never fouled a plug. Ive changed them once in while when the outside of the plug got all corroded, rusty lookin.

 

Yes, my last Polaris was an '06 600 Edge Touring with 600 liquid cooled carbed engine and it never fouled a plug the whole time I owned it. I did change them out once per year..just because it was easy to do and cheap insurance, but not because they were fouled. I would typically replace them after the first ride of the year after it had had a chance to burn out the extra oil from summerization. But never had any problems. If anything, the '13's should be way easier on plugs than my old carbed engine was...unless there is something else wrong with it.

Edit: fixjunkdaly said: "In the first 100 miles with mine it fouled 4 plugs because I disregarded the temp guage." But you might be jumping to conclusions thinking it was the temperature. When I picked up the sled, during the delivery briefing from the sales person, he indicated that it might possibly foul a plug or two during the break-in where I had pre-mix in the tank - due to the engine basically being fed double oil i.e. both pre-mix gas and from the oil injection. Mine didn't. But your first 100 miles would have been all or mostly during that first break-in tank, right where they told me to expect I might foul plugs.

 

Id rather put plugs in than leaving with a cold machine . I don't let mine idle all day . when she pops a plug its usually within 1 minute of being started . cold scuffing my piston is the last thing i want to do. I wait until she is 100 before I start touching the throttle . I have had sleds for over 20 years now and i always let them warmup and never had plugs issues . I think my oil pump might be set to rich or defective. the guys told me that these models are extremely good on oil however i don't find it any better then my old 96 xlt .

I did called the dealer and he told me he have a customer with a 600 rmk that have the exact same issue he is going to call Polaris and get back to me .

 

I agree with the need for a warm-up - its just that I haven't seen anything anywhere (including the owner's manual) that says a particular number that the temperature should be before riding, so I think the whole 100 degrees thing is all guess work.

As far as fouling plugs in the first 100 miles, I pointed out that that's when you are running pre-mix for break-in but also the manual says (note where it talks about a new engine and also prolonged idle):

MAINTENANCE
Spark Plugs
Spark Plug Recommendations
A new engine can cause temporary spark plug fouling due to the preservative added during the assembly process. Avoid prolonged idle speeds, which cause plug fouling and carbonization.

On Warm-up it says:

Follow these steps to ensure proper warm-up of the engine, drive train and track.
1. Use an appropriate stand to securely support the rear of the snowmobile at the rear bumper. The track should be about 4 inches (10 cm) off the ground.
2. Start the engine and allow it to warm up two to three minutes.
3. Depress the throttle abruptly and allow the track to rotate several revolutions.
TIP:It will take longer to warm up the track sufficiently during colder outdoor
temperatures.
4. Release the throttle, apply the brakes, shut off the engine and lower the snowmobile to the ground.
5. Grasp the skis by their front loops and move them from side to side to loosen snow and ice.

Note it does say to warm it up but it says 2 to 3 minutes rather than a particular temperature. On my previous sled with no temp guage that's all I had to go on anyway (i.e. time + the fact that the carbed sled would let you know it didn't want to run yet). On my Ski-doo, when I first start it, there is a display that flashes "warm-up" and you aren't supposed to ride until it goes away. The manual doesn't say if thats based on a particular temperature but I'm guessing not because just like the Polaris manual it says 2 to 3 minutes. It also goes on to say "not recommended to let engine running at idle speed for more than 10 minutes".

 

1000 miles now, never a hichup. VES gold, everything original.

Did have blue flames out my exhaust the other night. Me and a buddy running hard down a trail for about 10 mins, pulled over to wait for others, standing on the left side of my sled i noticed the exhaust sound of my sled seemed weird,deep and throaty, joked to my friend it sounds like a Harley idling/thumping. He said Yah, you have blue flames coming out your exhaust !! :shocked:

should have looked closer myself, just saw the blue glow in the snowbank next to the sled. Shut the sled off quick and immediatly restarted it and it was fine. :dunno:

maybe i had the muffler loaded up with carbon burning off ??

 

On my 4th set! 300 miles, warmed up to at least 80 every time before moving!

 

Never seen that even once in over 1100 miles now. I really thing the issues people are having with plugs are probably not related to warm up. I am nowhere near as religious about warm up as a lot of people. I usually just go with the two to three minutes the manual says - though my actual warm up is highly variable. I usually start the engine so its running while I'm doing other things to get myself situated and ready to ride so it kind of depends on what I'm doing.

Still - never fouled a single plug.

 

I'm thinking the sled is running to rich I've thought that all along mentioned it to the dealer they shrugged and said no service bulletins on it yet

Hmm.. It's actually bad, I use a brand new set of plugs for 1 ride, then they are usually close to being fouled out, the next time I ride I let it warm up on those plugs, it usually fouls out, then change them, then ride.

Maybe I will have to try to warm it up for 2-3 mins instead of to 80-100

Would oil have anything to do with it? I switched to Ipone, thinking maybe I should go back to VES gold?

You guys getting the stumble at 39-4200 rpm? 24/7, constant for me.

 

I think the oil is too rich my plugs are black as black can be if it was a bad injector it wouldn't perform or am I wrong about that

Too much oil won't cause black plugs, too rich will.

 

But to much oil will foul plugs

 

I switched it over to 91 non ethanol and I am running 91 non ethanol fuel, seems to be doing better. What does this do?

 

A guy from an other forum suggested me to use iridium plugs, they are foul resistant. I have put on about 400 km so far so good they are expensive tho.

 

the sled is due for a inspection I am going to check my oil pump setting. I went with a buddy of mine that have an 12 rush 600 after a 400 km run he had about 2 inch higher than me left in the oil tank.

Probably an oil pump to rich . i'l keep you guys posted and once I take it apart i'l shout a video on how to set your pumps for the ones that want to do it yourself.

 

If it's using more than a 12 on the same ride, it's using way too much. It should use less, not more. We got a lot of snow where i live in MN and I've had a few days off so I've been out every day. I've ridden about 350 miles in that time (about 583 KM?) and the oil level is just a bit less than half way between full and the Add oil line. Mine sips it at a rate that doesn't seem to be much more than my 600 E-tec sled.

Why take it apart yourself? There is clearly something wrong with it that the dealer should fix.

 

So, any success on running shorter time on idle or maybe corrected the oil amount?.
Got a friend with this issue, it eats alot of plugs

 

IMO Polaris needs a recall for the fuel map on these sleds as they are pig rich at idle.
This weekend I let it warm up to 80 and then pulled away and avoided letting it idling at all when warm. No fouled plugs. The dealer also put me on to a different NGK plug, I think its starts BPR.
On the upside, first Polaris in probably 20 plus years and I'm pretty impressed with the first 100 miles we put on.

 

I have 400miles on my Indy and havent fouled a plug yet. Ive let it fully warm up and I have took off cold.

 

I've got 1,626 miles on my Indy SP. Anyone have me beat? Or am I the mileage leader so far?

I also have never fouled a plug. Any yesterday after my bounce off the ice, the sled kept going quite a ways after I departed it...engine still idling away. We had already ridden 90 miles so it was warm...and idled for about 10 minutes before I got my wits about me and got back on to ride it home. Still didn't foul a plug.

 

1200 miles , original plugs and belt. Never missed a beat yet.
