2017 Sportsman 570 X2 - Problems with EBS, transfer case and heat

Recommended Posts

Hi all,

I apologize if these have been discussed in the past. I just wanted to get this posted out here real quick, then will try searching through the forum tonight. So, I have a 2017 Sportsman 570 X2, with EPS and EBS. I have the following problems/challenges and am curious if I am not alone, and if any solutions have been found.

EBS - Holy cow! The engine braking system is so strong that Active Decent Control doesn't even seem necessary. On deceleration, it actually causes the tires to slide on dirt and asphalt! I have had the ATV for a little over a year and don't use it often. It probably has 30-50 hours on it.

Transfer Case/Transmission - I use a tow behind trimmer mower on my Very steep hill. It is not particularly heavy. While rolling downhill, I am usually in 4x4 (not with ADC, usually). The transfer case and/or transmission will suddenly pop into a neutral state. The shift lever and 4x4 switch do not move, of course. I am able to get it stopped with the brakes. Once stopped, It seems like it is engaged into gear again. That's without moving, shifting or changing anything. I do have a case open with Polaris on this one.

Heat - The ATV runs very hot. I generally use it at low speeds with a load behind it. The load is never terribly heavy. It's usually a garbage can, trimmer mower, driveway grader, trailer with a small load of firewood, etc. 

 

Bonus Question! I will post this to general too. I am a motorcyclist, riding on/off road for over 30 years. This is my 1st ATV, however. How in the heck am I supposed to operate the thumb throttle while at a full right turn? This is generally while trying to make a U-Turn. I tend to roll my hand over the top and grab the throttle from the front with my fingers. It seems very choppy, especially with the engine braking. 

 

Thanks!

Thomas

I have a 2018 570 eps. I find the EBS to be quite strong , enough to skid the rear tires. To overcome this I add a touch of throttle and apply brakes...when decending . It's just a matter of getting used to it.

Thanks, I’m slowly learning to feather the throttle and brake while engine braking. With the transfer case/transmission issues I am having, it looks like I’ll be taking it into the shop.

      So Id say about 2 years back I bought a 2013 Polaris Sportsman 500 H.O. off of my uncle. It ran perfectly, nothing wrong at all. I usually go mudding with it or just ride trails with buddies. So as you would assume, the quad is quite dirty from sitting for a few weeks.
       
      STUTTERING PROBLEM: I noticed one day out of nowhere that in high gear at 15-20 MPH, I was already maxed out at 4500-5000 RPM  It would get to 15-20 mph, max out on rpms and start sputtering. It sounded like it was basically acting like it couldn’t go any faster than this.
       
      IDLING PROBLEM: I was fucking with the carberator the other day maybe thinking that is causing my sputtering, and now my idle will shoot up to 2600 on start usually, then I will turn the throttle adjustment down to the normal 1400. The rpms with then fluctuate 10-30 rpms back and forth repeatedly, it will then run for about another 30-60 seconds and the RPMs will slowly drop to about 900-1000 RPM and stall out. I replaced the carburetor and everything seems to be working perfect on that, no leaks and what not but it’s still acting strange. Also, I’ve noticed that when looking into the Electronic Throttle Control that two plates that aren’t supposed to touch have to be WAY past touching to even try to fire up. Even when set at a wide open throttle like that, I still have to give it some throttle to get it to fire up.
       
      Here is what I have done so far: 
      Checked the belt and clutch
      Changed out spark plug (Last one was covered in carbon)
      Cleaned the intake and air box
      Replaced the carburetor
      Replaced the inline fuel filter
      Checked that all lines on carburetor are connected into the right spots
      Checked If intake boot was cracked (Not from what I can see)
      Unhooked and reattached new carburetor (About 4-5 times)
      Cleaned battery terminals and battery off
      Shut on and off Gas Line Cutoff Valve
       
       
       
      My next thoughts are that maybe the TPS is fucked up or maybe the Spark Arrestor is plugged with mud. I was thinking tomorrow to purge the exhaust and also check the ohms output on the TPS.
       
      ANY HELP IS GREATLY APPRECIATED. I HAVE BEEN BATTLING THIS FOR WEEK AND REALLY WANT TO GO RIDING. THANK YOU!

      Looking for the wiring diagram of the gauge cluster. Thinking about using it on my 2008 that I just bought.. Its gauge is destroyed
    • By Larry Fox
      Has anyone had any luck putting a different gauge on this machine. Would you happen to have the wiring diagram?
