Hi!  I just purchased a 2018 Polaris Sportsman 450 AWD. The instrument cluster reveals 306 miles, ENG 75.5 hrs, and Service Due 83.4.  Oil and coolant are clean and levels are good.  Air filter is also clean.  Everything shows the ATV is in excellent working order.  But... every time I start it, the check engine light lights up (no code is displayed).  I am worried the light may indicate something serious, but I can't figure out what.  Any ideas/suggestions will greatly be appreciated.

I had similar thing happen to my 2021 Sportsman 1000.  Started it after it had sat for 3 months and got the check engine light.  User's manual was worthless and said to take it to the dealership.  So I walked into the service center and asked what it could be.  I was told that it could be any of 100 different things but one of them was a low battery voltage.  Since the reason I started it was to charge up the battery I thought that was probably the reason.  Service manager said it should reset the check engine light after 3 or 4 times of using it.

      oil for air filter?
      By Mikey509
      Hi everyone, first and foremost, I want to thank everyone for all the help I've received. I am so glad I found this community. I also wanna apologize if I'm spamming the forum, I come up with questions as I go, I guess lol. So when I got my Recon, the air box was missing the lid, held together by zip ties, and the filter was ripped and nasty. I have since ordered a new air box assembly. It comes with everything: the box,  lid, and filter ( the insert and the foam), and all the hardware necessary. This is the first time I've seen a metal filter inside a foam filter lol. However, my question is, I have read that you have to oil these filters? Every time I read it, it was always skimmed over, and I could not remember where I had read it. Is there a certain oil needed for this? Is the filter washable and reusable? Do I just stick the filter in oil, lol? Sorry if it sounds like a dumb question. Thanks in advance, y'all!
