2010 Polaris 800 RMK problems

I just had this 800 RMK to the dealer for two serious repairs. One: the fuel pick-up assembly in the tank fell apart. A Polaris rep told me that eth-gas will do that. The sled is supposed to run on either eth or eth-free. There was no heads up from Polaris. Had to drag it 45 miles out in deep powder. Two: During this repair the tech noticed that the display was going dark. This he said was a signal that the voltage reg was going out. The cost to repair that situation is upwards of 1000.00 with parts and labor. An up graded voltage reg is available which can avoid replacing the computer. Again no heads up from Polaris. Either of these failures could get a sled-head in deep ----- at -25 degs.

Just a heads up.....not very many 2010 Iq's go to the deep back part of the woods anymore. Most stick pretty close to the cabin, warming up chef Boyardee in there muff pots. Rumour has it that these years of sleds weren't very reliable.

Welcome to the site...by the way.

Sorry to hear about your troubles. One more to watch out for on the 800 engine is piston failure due to poor design. Do a search for polaris fix kits. Almost guaranteed to make you switch over to another brand.

The sled is 8 years old! You are doing pretty good! They all break, Some years of some brands break more than others.


But not manufacturer sends out a group text or face book post to all the owners regarding possible issues. The engine has the reputation of being the week link on that sled. If the sled is running ride it and have fun!

Get a service manual or a second opinion before you dump a bunch of money into your dim display issue.

Check it with a volt meter, and ride it while there is snow on the ground. Probably easy to find parts from a sled part out when you need them.

If you decided to keep this sled, I suggest taking apart your gauge pod/ air plenum and checking all the little screws and bolts. All those little screws have are exposed to the air plenum, and the air box has no false bottom like some of the older IQ chassis machines. I had a little screw fall out of the inside of the dash, and go directly into the crank case, after destroying a reed valve and leaning out a cylinder. I was even considering gluing a magnet inside the air box. I limped my dragon out of the Renshaw with a piled up voltage regulator. Unfortunately it cooked my fuel controller on the way out. Changing the voltage regulator is about a 5 minute job, and if i remember right about a $200 part. My advice, get an AXYS
