Hi all,

First, I wanted to introduce myself by saying "Sorry to post my first thread with a problem" but we are pretty frustrated. It looks like there is a lot of knowledge and experience in this forum, so I am keeping fingers crossed for some help.

We are not new to ATVs. We had two Honda Rubicons and a Can-Am Outlander 400 prior to this year. Last month we bought an orange burst 2016 Sportsman 570 EPS for my wife and a 2016 Touring 570 SP (Blue Fire) for me (Broncos colors!). We intend to keep them at our cabin at about 9700 feet.

We got them on Saturday afternoon and went out Sunday morning with them. We were going up regular forest service trails and varying our speeds. At about an hour and 45 minutes into the ride the orange one starts to sputter and lose power. Then it died. Started it again and then it ran but would not rev past 2800rpm and went real slow. Shut it off for awhile and waited. Started again and it ran fine. We continued our trip up and went over lots of rocks and up some steeper terrain. It got to the top just fine at 12,400 feet. On its way down, however, it did the same thing, but much worse. Was really hard to restart and would just bog along. We took the air filter cover off and it ran ok so we put it back on and it went for about 20 feet – same thing. We kept doing this drill for about a 1/4 mile. Finally, after the last bout, it started and was running well and I just kicked it and went straight down. I stopped a couple of times with no issues.

We took it to the dealer (they picked it up, actually:hump:) and they, of course, could not re-create the problem. Polaris had told them to try a couple of re-routing of things (I was not told specifically). They said they ran it about an hour and a half and took it up high with no issues. So we got it back and went out the next weekend. It started acting up again. This time it just stopped. We had been able to do the same trip as before, but coming down it just did the same thing. It had made it longer/further before incident however. This second time, it would finally just not start again so we left it on the trail in a clearing over night.

Next day, I went up with a tow strap and of course it fired right up! I wanted to video what it was doing for the dealer so we went back on the same trip. Got all the way up and almost back to the clearing again with no incident, but then it did it again. I took 5 videos in succession. They showed it bogging down and losing power. RPMs would only go to about 2300 and it would stop moving. Hi/Lo gears made no appreciable difference other tan a slight speed difference. I vented the gas cap as the dealer said Polaris said to do. Same result. So I towed it home. Got it back to the dealer. They again cannot re-create it. They saw no codes. (I never saw any ‘idiot’ light illuminate on the display during any of this.) They seem stumped and Polaris says they are stumped. They said my videos did not help to diagnose the problem because it was not on the computer.

One last aside. While I was hooking up the tow strap, I noticed a brake light bulb dangling from my touring machine. The bulb had not been twisted in or seated well enough apparently so the bulb rested on the plastic opening and melted it! The plastic dripped into the hole so that I could not even put it back in.

Needless to say, I am so far not impressed with the quality of these machines – which is too bad because we really like many of the features but especially the ride and handling of the machines.

Any thoughts on what the problem may be would be greatly appreciated! I called another dealer’s service department and he said it could be the O2 sensors. I put my shop in touch with him and now that theory seems to be discarded. Everyone is scratching their head.

Thanks for reading and any thoughts. As above, sorry to start out with a problem.

What do you wish for on the 570 line? Please, let’s not fill this up with wishes to fix current or past problems. Just what would you like to see new or done differently? Remember: this is a wish list, so no need to argue the practicality or possibility of anyone’s wish.

1. I’d like to be able to shift from low to high, and high to low range without stopping.

I probably have more, but this is the one that bites me on the trail frequently, when I’m riding with others and have to stop. And on their XYZ brand they don’t. I always use Low Range for serious climbing or etc.

Non-570 wish
I wish I lived where I could ride everyday! Love climbing and treading mud!

It is my first year of xc racing, I have ran 9 races so far and still can’t get rid of the famous arm pump, the day after a race everything from my neck down is sore you’d think after racing so many times it would fade lol. I have changed my bars multiple times, the position of my bars, tire pressure and even adding a CCP stabilizer. I’m on a pretty tight budget and don’t have much down time to go practice. What do you guys think would be the next best investment to help… Flexx bars, revalve my stock suspension or maybe +2 steering stem. I’m 5’9 190. Or maybe just my riding style?

Thanks for any advice.

My wife has a 2015 570 and on every ride it quits exactly once. It usually happens as she just comes to a stop. Sometimes it happens within the first few miles of riding and at other times it happens well into the day’s ride. It only happens once each ride (day) and when she tries to re-start it usually takes several attempts but it always eventually fires. I haven’t been able to determine any consistent causal effects, like always when its wet, always after a hard pull, etc. None of the idiot lights on the dash show anything is out of the norm like overheating either.

Does anyone else have the same issue or any ideas on what to start looking for?

I have 14 570 sportsman and when I put it in gear it just revs up and don’t move. I’ve tried high, low and reverse.
Has anybody had this problem or know how to fix it.
Thanks in advance for any help.
