does anyone have a repair manual for a 2018 king quad 500 se eps?

So I have used the service manual to troubleshoot every sensor on this bike. Everything tests good accept the EPS Control unit. However, I do not see anything in the manual that suggests that this will cause the issue that I am having. The bike will start instantly when the button is pressed sometimes and then other times it wants to turn over forever and make a horrible knocking sound. Sometimes backfiring. After cycling the ignition it will sometimes start up right away. I have triple checked the timing and also the valve clearances. Everything checks out. The bike is for a customer that really doesn't know anything about the bike. From what I can see, the cylinder appears to be new, along with the starter. I did a compression test and it is a little high (74psi) Book says 71.7 is max. I can't see this little bit causing the problem, but I could be wrong. Last thing is that the idle is a little high. I have tried everything to get it to slow down with no avail. When I put it in gear it will jump slightly and is hard to get back into neutral due to high RPM's. Any Ideas or suggestions will be greatly appreciated.

The EPS on my 2011 Suzuki King Quad 750 is not working; the warning light is always on & the steering is ok to the left but very hard to the right. Can anyone help??

I have a 2018 Sportsman 570 SP Hunters Edition. I bought the quad new in August of 2018 and put around 20 miles on it with no issues. In early January of this year the quad was acting as if it had a bad battery even though it had been plugged into a tender. I checked the battery and it tested well so I took it to the dealership for warranty service. They had it for almost a month. They determined the quad had a bad EPS unit and swapped it out. Then they told me that the wire for the EPS needed to be updated as they could not program the new unit with the old wire. After the wire came in dealership told me they were still having troubles programming. After another week and a half they told me that they had consulted several times with engineers from Polaris and found a workaround and that the quad was ready for pickup. I contacted Polaris to inquire about the warranty being extended as it was in the shop for a month. They extended the 6 month factory warranty for an additional 3 months. I picked the quad up and the dealership said that the 2018 SP editions were known to have issue a with the EPS units but believed that they had fixed mine. I had it back for around a month and took it out a couple times for short rides and everything seemed fine. I parked it again for a few days and when I went to start it same issues (acting like the battery is no good and won’t start, when I jump start no power steering). Took it back to dealership and waiting to hear what the diagnosis is this time as well as their plan to fix this permanently. Just wondering if anyone else has had issues similar to mine or can give me some advice. Thanks in advance!

Just have a couple questions first does anyone else have an issue with the right hand tie rods coming loose second does anyone else’s power steering making a weird sound at times

I have a 2016 sportsman 570 eps And have a vibration around 25mph, goes away around 30, then comes back around 45 to WOT. I've heard of the motor mounts being bad but have had it to the dealership and they say nothing appears to be worng. Anyone else have this issue and fixes please.

I have a 2017 Sportsman 570 SP with a power steering issue. Dealer tells me my machine is one that is not covered by recall and offers no help other than bring it in they will look at it. Any ideas?

I have a 2018 Kodiak 450 EPS that just this past Sunday I ran through a bit of water. After the puddle the belt was slipping, so I pulled over and drained the ultramatic housing and the slipping problem went away. This was all in L and everything seemed to work fine. Later when I got on a road, I put it in H, but it still rode like it was in low... i.e. I had to rev it up a lot just to get to 30mph. When at home I pulled the ultramatic cover off to inspect, and it looked okay in there. Not much dirt, belt and everything are clean, but when I rev up the engine (with cage in place, of course), the belt doesn't get to the top of the clutch (maxes out about an inch or 1.5" from top of clutch, so maybe it is normal).. I put it back together but same thing... H seems like L still. Do you think the clutch needs to be further dissected for cleaning, or could this be an issue with the gear selector?

Hi Anyone else with a 2017 sportsman with EPS, experiencing hard lock up with the CVT clutches. As compared to my friends 2006 Polaris 500 HO they seem to be a lot smoother engagement. Any ideas or is this normal for this model.

I have a 2012 Suzuki king quad 750 with EPS I do believe the power steering is not working, I have a plow on it and have to pull very hard on the bars to move the front tires when not moving!! When Moving it is OK, have only been around a Polaris and sitting in the garage I could move the bars with my pinky finger only. Not the case on my king quad. Fuse is Good, EPS light comes on when started but shuts off after few seconds, I believe this is normal I have a black and a green wire coming out of bottom of the handlebars, under the headlight, Not sure when theses are they are not hooked up to anything Would love any insight on where to check or what to do Next Matt
