Recently bought a Polaris 425 Xpedition. Main issue is that the quad randomly misfires sometimes. ONLY does it at idle. Everything sounds good. What should I look for? Haven't checked the plug, seems a bit hard to get to, not sure. Headlights flicker at idle as well, is this a sign of a weak stator? Help?

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!
I have an Outlaw 110 that will struggle to turn the engine over. Jump starting doesn't help other than the battery will drain LONG before the bike eventually starts, so is required. If you keep messing with it long enough it will eventually magically begin to crank fine and sometimes finally start. Once we finally get the bike to start and warm it up thoroughly, it will turn over and start just fine the rest of the day like nothing ever happened... next day it won't turn over again. Internet research has found lots of people saying they replaced starters, starter clutch, wiring, etc. but with only about 50/50 success rate for their particular problems... and I never found anybody describing a problem like mine, so I'm looking for advice/experience. Would rather not just start blindly throwing parts at it. Does anybody have any thoughts/ideas?
just bought a 2000 polaris 325. was told i vould pull start and ride but needed new battery for electric start. so bought new bat and charged it but nothing. while spraying with a hose after a ride it all came on. neutral light cooling fan and then quit. checked those things in the black bag and power at both ends. starter will roll when i jump solenoid. power to the ignition switch jumped that but still nothing. maybe switch for headlight and starter? NEED HELP PLEASE.

I live in Minnesota and bought a 2016 CFORCE 500 HO. I am in hope to see if there is anyone in the US that is experiencing this sudden drop off in RPM below 4000 RPM. I have uploaded some videos of my issue on YouTube. I will list three of the four I posted. The fourth can be found on my channel but it is a comparison between my Polaris 570 and my CFORCE 500.
I quit on my first dealer because we just did not mix well together. I brought it to another CFMOTO dealer that just became a CFMOTO dealer in January 2016. They are in a large ranch and agriculture area in a neighboring state that is pretty close to where I live. They have close to every brand available. They are a much larger dealer than the first one I bought the unit from.
I brought the unit three weeks ago to them and they have worked on it a good solid week and have given up on it. I have read reports from owners in Canada that the dealers there were aware of the issue and have had success in fixing the herky jerky drivability issue.
I am picking it up tomorrow and bringing it back home. It has been to the trails of the Black Hills this year and was new in late April. 300 miles on it. It has never changed. Very hard to ride on the trails or when I herd livestock.
Here are the links to my videos.
I can't accept that this is normal operation. Does anyone from CFMOTO China scan these posts?
I need help that CFMOTO USA has not provided.
Has anyone found engine oil in their air filter box. The must be little or no baffle between crankcase ventilation and that hose that attaches to the air filter box.
I went to pick up my ATV today 60 miles away that they could not fix the jerky low speeds on and before I loaded it decided to check on this. Sure enough there was a good coating of oil with some pooling in the bottom of the air filter box. The air filter has oil on it too but is it a dry element or oiled element type. My guess from the color of it dry.
I heard on a comment on my YT videos that there is a kit for this issue? Is this a CFMOTO fix?
I am having an issue where it sounds like the gears are slipping if I hit the throttle really hard and also after letting off when the engine brake is applied. Also, the drive train that goes to the front also rides again the gear shift box. I will attach pictures and a video here shortly.
Thanks in advance!
