Just wondering if anyone else is having trouble with the 07 IQ 600 CFI. Just had engine failure at 750 miles. Nothing but trouble with it for the 3 weeks I have owned it.

1,200 miles so far this season and not a problem with mine. I love my IQ.

Did your dealer tell you about the Service bulletins?

I hope you broke in the engine properly and had these bulletins done. Something tells me no.

2200 miles and it runs like day one. The only problem I've had is two sets of fouled plugs.

I don't know about breaking the motor in "properly", my theory is to ride it hard hard as you can from day one. If something is going to let go I want it to happen on the first ride.

There's lots of reasons that I motor could fail, it's important to find out the cause before it goes back together.

I did the motor break in according to the manual...took it easy and used oil in the gas. I had the 250 mile service completed and did report to the dealer that it was sipping oil. I brought it in again at 500 miles for the oil pump sync. bulletin...had it completed and again reported that it was hitting a peak rev of 8650 and just sipping oil. Brought the sled back again just hours before it seized and reported that it was still hitting 8600 RPM's and sipping oil....I even gave them the stats...3 liters of oil for 350 liters of fuel. Again the dealer told me it was normal.....three hours later it locked up. I don't know if there was anything else I should of done???

That means you were running about 115:1 oil ratio, should be a lot closer to 50:1 I would think. Sounds like you were under oiling? What is Polaris going to do? New motor or just fix yours?

THe response from the polaris dealer was quite amusing...I was told they could look at it in about 2-3 weeks and it could be even longer before the get the parts to do a rebuild. I asked about a complete new engine and the response was a flat no....just parts to fix whatever is broken. Now that's great service!!! I brought it to another dealer outside of the city and they agreed to look at it early this week.

Check the oil pump yourself. Dealers have a tendancy to not care if they did service properly.

And the most important thing is to actaully check your oil pump. Mine was checked as per the service bulletin. I got it back to my house and checked the sync myself to be sure it was right, and it was. 1000 miles later it wasnt burning much oil at all. So I decided to check the sync again. And what do you know... The oil pump wasnt opening until about 3/4 throttle.

And even worse, I decided to check and be sure the oil pump was set at the the proper adjustment for cable slack or idle alignment. Sure enough. The cable was completely slack... And the oil pump arm was being stopped my the motor mount it was so out of adjusment.

Somthing definatly made it past the quality control dept on these sleds, but I can almost assure you that this was your problem.

I highly recomend that everyone check the oil system themselves on every sled they ever buy. It doesnt make sense to rely on your dealer to do the work. Do it yourslef any you will get quality in return.

8,600 rpm? Sure sounds pretty high to me, at least for a stock sled. Anybody else turning that many R's?

Sounds like it's time to give up on that dealer and write a letter to Polaris with regards to your service experience. Pretty shoddy work from the sounds of it.
Curious, was it the dealer that sold you the sled?

Way too high. Should be 8200 I believe.

The dealer where I purchased the sled is the one that told me it would take 2-3 weeks just to look at it. I trucked it to another dealer 2 hours outside the city and they are willing to look at it early this week however definitely won't get it back before the weekend. All three Polaris dealerships in this area are owned by the same guy. I'm still trying to get a demo for the weekend...no luck yet.

I hope everyone at least read what I said above about the 600 cfi oil system being way off.

I have already heard of 3 600 cfi motors blown.

Also where are you getting the rpm's from, if your looking at the peak RPM's reached in the computer, that is not the info your looking for. If your sitting at a stop and slam down the throttle its going to jump over the 8200 mark until the clutch shifts out, which should be very quickly. If your at full throttle and have been holding it there for a while and it still says 8600 on the tach (dont use the digital gauges for the rpm's, only the analog for the best reading) then you are way to high. At full throttle across a lake mine only does about 7900 rpm's or so, and that is at about 96 MPH. But if I were trying to drag race and mash down the throttle it will jump to roughly 8600 RPM's for a second, which is not usually bad, its only the sustained high rpm that you should really worry about.

This problem is very very unlikely the culprit of the burned down motor, but HIGHLY likely from the lack of proper oil setting from the factory.

I realize the RPM is just a peak...on top end 95MPH or so I noticed a digital reading in the range of 8150-8200. I never really checked it on the analog. As for the oil pump issue... I kept crying foul at two different dealers for two weeks and they completely ignored me and told me to keep riding. I guess I have their attention now. I made a few calls today and got the General Manager of the dealership on it. The machine was being stripped down late today....I should know the problem in the morning. I'll keep everyone posted. Thanks for the info.

I purchsed the sled in St. John's,NL at Coastal Marine and Recreation. The owner also owns two other dealerships outside the city. I actually brought it to one of the shops outside the city for repair...not near as busy out there.

Thats exactly it though, the top speed rpm is right where it should be. If your just looking at the top rmp memory function your not actually seeing the important detail. Sustained speed at anything over 8400 could very likely cause engine damage, but please note that the damage to high of rpms would cause is much more likely to be in the crank bearings that the pistons and cyls.

If you burned down a cyl then it is the cause of to little oil or improper air/fuel ratio. And if I could shake your hand I would actually bet a new motor on the fact that you werent getting enough oil becuase these things are way out of adjustment from the factory. Burning 1 gallon of oil to 1000 miles like I did is absolutely unacceptable, granted the true factor is how much gas I burned during that 1 gallon of oil, but it was way to little.

I am actually leaving on friday to take about a 600 mile in 3 day trip, so hopefully my new adjustments to the oil pump will actually prove to work properly. I am looking to burn about 1 qt of oil every 100-150 miles to start, instead of 1 qt every 250 miles. Then I will start to adjust to get the proper 50:1 or so. Granted in these new injected sleds your not going for a perfect 50:1 ratio. Maybe we should just run pre-mix. Unfortunatly for me that wont work because I take long tips like I will be this weekend and need to have an oil injected sled. So finding an acceptable oil injection ratio is critical.

So this weekend I will be around 1800 miles and crossing my fingers plus knocking on wood that this thing isnt going to follow the fate of other 600 CFI's so far.

Got the news on the engine yesterday...its a 4 point seizure on the PTO side. They blame it on improper warm up. The machine was definitely warmed up at the time the engine failed. The oil pump was functioning properly according to the mechanic however it is still only mixing at 100:1 or a little lower. Should have it back in 3 or 4 days.

Are they just going to un-seize it and give it back or are they going to replace the piston and rings?

Are you mechanically inclined enough to check the oil pump yourself when you get it back? Because if you have the ablitiy to do that yourself it is a must. If you arnt comfortable doing it yourself find a friend or someone you know who will have the abitity to check it. Heck, if I were you I would even think about paying the extra money to have it checked and adjusted by someone else. These sleds will be out of warranty soon and I dont think you want a blown sled when its out of warranty.

Hearing about all of these blown 600 CFI's I am getting pretty nervous.

Just came across your post , and Wow, sorry about your misfortune, but i'm replying, because a friend of mine quit Coastal, because of there work ethic , and constant screwing of customers , are you getting the jist of this now , apparently there are several law suits ongoing as we speak involving polaris and coastal marines work practises!!!

As for the oil pump I could probably check it myself however I watched the mechanic at the shop check it yesterday with it off the engine...it was flowing fine....I did ask to have it turned up to use more oil...its being done. The dealer is going to replace the piston/rings/ and cylinder. I looked at the rest of it and I have good faith in this dealer I found outside the city....they are treating me pretty good. THe service manager is actually the mechanic doing the work. As for COastal Marine in St.John's....I have heard alot of horror stories and in the last while both the service manager and warranty guy have both packed it in....too many complaining costumers...including me. IDigem...was your buddy's name and contact info...he may be of assistance in the future. As for Warranty I have the three year package so I guess I have another two seasons to see if anything else will go wrong...thanks for the input.
