I have put about 10 miles on the IQ and it has fouled the mag side plug twice. Also the throttle cable adjuster under the airbox came loose. This allowed a ton of slop at the flipper.(about a half inch) The carbed sleds with the throttle safety switch would not have started. luckily I was at home with tools.After restarting again it fouled the right side plug . Good thing I had two sets of plugs my 03 pro-x has never need in 4600 miles. This time I just replaced the mag side and she runs crisp for now. rode it around the yard and ran her back into the barn,snow is melting so further testing will have to wait at least a week or more. If anyone has a similar problem or solution please post. My 03 pr0-x 6 and my wifes 03 xc500sp have never fouled a plug in four seasons and they are stock rich jetting.

There is a TSB on this unit. Have your dealer check Bulletin#S-06-14A & B

2007 600 CFI OIL PUMP/THROTTLE BODY SYNCHRONIZATION INSPECTION

Click to view attachment

I just put 52 miles on my new 600 CFI Switchback this morning and it was incredible. Huge power, great throttle response, and good fuel mileage so far. I was riding with an F6 and the Polaris 600 CFI has way more power from bottom to top. My buddy fell in love with the SB 600 CFI right away. I am sorry to hear about your bad luck. I can't wait to ride more but we will need more snow before I can head out again. Have a good season!

Very sharp looking SB!

I put 38 miles on my 600 CFI yesterday. No troubles. Just pure excitment :div20:

The throttle response is incredible, the ride is comfy, and the sled feels light! I can't wait to get more snow.

I share your pain, the EXACT same thing happened to mine on Thursday, Talked to me dealer and he gave me the "double oil song and dance" it is going in on Tuesday to have the coolant hose shortened, and the oil pump adjustment checked, I will let you know the results. Also my old Pro X and my '06 Fusion still have the orginal plugs in them.

My 600 CFI is now on its fourth set of plugs, in twelve miles. The original set lasted eight miles. As far as I know no additional 2 cycle oil was added to the gas. I heard at the dealer that on CFI's no extra break in oil is needed in the first tank. The gas in it is what came from the dealer. Something seems definitely wrong. Of course you read that my throttle cable came loose at about 10 miles. Had to pull air box to get to cable adjuster- lock nuts had come loose and spun way out of adjustment. Unfortunately the dealer I bought it from is 300 miles away from home. I am going to call a dealer that is about an hour away, where we bought my sons PRO-X, 2 years ago, on monday. Over the last 10 years I have bought 7 Polaris sleds, from 5 different dealers, and none of them will promise better service, even if you pay them several hundred more for the sled. I'll mention again, I have 3- 2003 models that have performed flawlessly with no warranty isssues ever.

My wifes 07 IQ LX still had the tag on the tank. It said to add oil to first tank. Dealer is big on running winter gas (has additives) so he put 3 gallons of 40 to 1 in and told me to add 1 pint os oil which he gave me and fill with gas.

Does your sled have a Service Bulletin completed sticker on the airbox for S-06-06 which is the oil pump - Throttle body synchronization inspection and adjustment?

If not, make sure this is done also.

No sticker on the airbox...thanks for the feedback.

I got over 150 miles on my sled and it rips. I put oil in my first tank and it ran good. Got 123 miles to the first tank. getting 100 to 104 mph so far running the rip saw too. sled is mental..

What he said.
See the thread related to the new Service Bulletin. I just posted the actual bulletin for your reading.

A friend’s IQ 600cc CFI ran good for 20 miles in the UP. Then started to bog down when hitting the throttle, backfired several times, only go 5 to 10 MPH. It finally caught on fire due to excessive gas in the muffler.

His dealer’s service tech found a bad connector that had a pin partially pushed out and shorting out the brain box.

Trouble shooting suggestions:
1. Check for excessive throttle linkage slop.
2. Unplug all ECU wire harness connectors, inspect for bent back pins, clean & reconnect.
If this does not correct run-ability problems return sled to dealer for trouble shooting & repairs.
3. Many past Ski-Doo SDI problems corrected by unplugging connectors, removing “dielectric grease”.
4. In the past I have corrected 25% of our electronic hydrostatic controller problems by having the service mangers just unplugging connectors, removing “dielectric grease”. These electronic controllers handle very small voltage; dielectric grease is not a good conductor of electricity. CNH (Case Corp) does not allow dielectric grease on electronic controller wire harness connectors, even though it is good for stopping corrosion, resists water & etc. Good luck; Rich

my sled is now at a dealer getting checked out. The thought of it catching on fire did ocurr to me when it was running on 1 cylinder and back popping. the throttle cable free play adjuster nuts had completely spun off and the lower nut had slid down the cable and could have jammed the linkage. The nuts could not have been tightened at rhe factory... lots of bad things could have happened. I reset the nuts to what seemed like a slight amount of freeplay. The manual shows and says nothing. With CFI you can't do much without the correct software. I think the ECU needs reflashed. Until the shop lets me know what was causing the wet fouling I won't know if the "slack" cable was even part of problem. I'm really bummed and starting to think I should 've bought the carbed version.

Man that sucks that you guys got shitty sleds. Hope they get them all fixed up soon. I am so glad my sled never turned out to be shitty. Is it is just a few that are messin up or lots? Nice going polaris.. Way to get back to #1lol

SORRY,

I don't know where I came up with that Service Bulletin number, it has to do with FST's, I guess you could call it a cross-posting or just a blunder.

The Service bulletin for the 600CFI oil pump-throttle body synchronization inspection and adjustment is S-06-14AB

Just picked sled back up from dealer. Tech said oil and throttle cables were way out of sync. dumping way too much oil versus throttle opening. Polaris service bulletin was more worried about the opposite-too little oil. I just wonder how my cable came loose with so little time on sled. I hope the assembly workers are not disgruntled because of the recent lay-offs. Well it seems to run ok on the stand, can't test because of no snow.

its the dealers job to make sure every thing is adjusted and set right before they hand over the sled too you.
or if they did the mechanic is not doing a very good job.there is a bit more to setup than just bolting on skis and windsheild out of the crate and say "all yours take it home"


so keep blaming POLARIS for dealer setup

oh if you bought he carb model you might have the same problem because dealer never sync the cables or forgot to tighten the lock nuts :frech32: :frech32:

Why should the dealer have to do it all??? They might make 500 bucks on those sleds. 1000 if they sell them list. That is bull shit... Polaris should be putting these sleds together right at the factory. They make them for half what the dealer buys them for. They make the killin on the sleds. They are just stupid. It gives them a bad rep and when you want to be #1 again you wont do it by having this SHIT happen... I don't mind the oil pump coming to rich. Just break it in and then take it back for the 500 mile check and then get it set up but it should never come to lean... thats bullshit!!

EXACTLY!!!!

Dealer prep is actually quite involved, they should be checking the TPS, Cable adjustment, clutch alignment, Ski alingment, Camber, Software version, And everything else on these sleds!
But many just bolt on the ski's, and send it out the door. and then we wonder wy it doesn't work right!!
Although Polaris pays very little for dealer prep, it is no excuse to not do it correctly. if they cannot afford to do it correct the first time around, how will they afford to fix it when it comes back??


Dealer set-up is the difference between a good one & a bad one, I know, I had a bad one!!
