Did my first oil change today. Went smoothly. It's pretty easy if you suck out the oil container first. I was cleaning my foam in the airbox and I noticed it wasn't it's normal oily self. When i squeezed it out it was full of gas. It was pretty clear and not oil contaminated. This is strange for sure. I have no Idea why it would be full of gas other than the thing is running so rich it's getting gas in the oil and the vapours are liquifying again in the airbox. Any other time I've cleaned it there was oil in it, mind you the oil was very thin. Must have been diluted with gas. I guess when I took out some oil to bring the level into the noraml area on the dipstick it stopped the oil from getting into the foam and just let the gas vapours through.

Oh and BTW Hey Polaris 3 Qts in the oil change kit is not quite enough. What else is new they probably never tried changing the oil during "testing"

Mine had an area of the foam about the size of the palm of your hand that was oil saturated. I squeezed it out, and then squeezed it inside a paper towel. There was also small amount of oil in the waffling on the bottom of the air box, I sopped this up with rags. There was absolutely no smell of gas. I have hit some long stretches of washboard and small moguls at speed, the oil may have been from bouncing out of the cyclone.

I used very close to 3 quarts, but I filled it to the low mark.

The air filter was very clean, a few small dots of oil on it.

I concur with both of you. Did my first change last week and needed a "smidge" more oil than the 3 qts. Luckily my dealer gave me 1 quart when i brought it home. I also noticed exactly what Excursion described but i also thought it was a bit runny with a hint of gas smell. Suppose it's running a little rich and once Polaris remaps the computer we'll do a little better on MPG.

They are running too rich, I overheated mine and warped the head, or the head was already warped ( not sure ) When I picked up the sled after the repair they showed me the old head , it had 46 miles on it and was heavily carboned up, the spark plugs were replaced too , I saw them they were black no tan color at all just jet black, sled needs to be remapped for air fuel ratio

Well I decided to reduce the oil level in my sled after I noticed oil running out the front of the airbox and down in front of the primary clutch. This after a 99 mile ride. When I found gas in the foam it wasn't a small amount. Infact there was gas inside the airbox under the filter. When I squeezed the foam out it covered my hands and was dripping off. This is no small little thing. That was after a total of 210 miles of riding. I can just well imagine what this is doing to the engine internals. Washing down the cylinders and contaminating the oil. My gas mileage is the same as everyone elses (15.5 mpg imp 13 mpg US) so it isn't just a problem with my sled.

From another thread:


Although I remain optimistic about a reflash for the fuel mileage, my gut feeling is that it wont happen. I know that heat was a MAJOR issue during the exhaust component R&D. Any increase in EGT would be a concern for Polaris and I don't think they would plan on running them lean of peak EGT. Having said that I hope I am wrong, mileage I can live with premature wear is another story.

I don't want to come across as a wet blanket but here is another concern: Has anyone looked inside their intercooler? I had to pull mine off for another reason and found it to contain about an ounce of oil. The air filter doesn't have any oil stains so I don't think it came from the airbox. Machine has 300 miles

I would only hope that they would do a reflash as mine runs very rich and is almost undrivable between 5500- 5750.. exactly trail speeds!!

I was told that a reflash is forthcoming for the rich condition, the 5500 RPM thing, and the fuel guage. Now that certainly doesn't mean that they'll do it...remember what Polaris did about last year's fusion(Nothing) but hopefully they'll do the right thing this time.

Actually now that i've removed my plugs and inspected them i can say that a new map has got to be A MUST at this point. My sled has 400 miles on it and the plugs are BLACK AS BLACK and SOOTY. I don't think it's a matter of "wanting a flash" but rather "needing a flash". There's no way a 4-stroke should need plugs at 400 miles. My Yamaha 4 stroke ATV is not EFI and it's 6 years old...i've never replaced the plugs and i can start/stop it as often as i like without fouling plugs.

POLARIS!!!! I love my FST but it is running way too rich! 4 strokes should not foul plugs this easily.

I blew a belt and it put a hole in my belly pan in front of the clutch. I put a new belt on and smelled something like burning rubber for the remainder of a 850 mile trip. I thought it was a piece of the blown belt lodged somewhere. After closer inspection when I got home it appears I had Quite a bit of oil and fuel leaking out the 4 drain holes in the front of the air box. Yes they are there, remove the box from the clutch cover to see them. The foam also had fuel and oil in it. I think my belt was getting fuel and oil on it and may have caused the blown belt at high speed. I cleaned everything up real nice and taped the 4 holes shut for now untill I find out what is going on. I will have to watch the bottom of the air box and clean any oil/fuel buildup for now, but its better than this getting on the clutch and belt. My temp gauge will not go over 125 and is very erratic. I think its the sensor and am getting a new one. Maybee my sled is running real rich because of that. I thought I read that the sled does not go closed loop untill 120 deg. Mine bounces below 100 every couple seconds. Where is that senser located anybody know?
