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.

      I just bought a rare beast!
      By kawasig
      Hello All
      I'm kinda new to ATVs. I just bought a 1987 Suzuki quad runner 230 Dual Range. I'm having a problem finding info on it. It's very clean, only 2.800 miles. The front wheels are only 30 in.center to center. I was thinking about adding wheel spacers to give it more stability. I realize the added stress on ball joints and bearings. I'm wondering if there are any other concerns? Any input is greatly appreciated!

      Heavy Duty ATV Cover
      By Gwbarm
      Does anyone have a recommendation of a really Heavy Duty ATV cover. I have bought several and they do keep the water off somewhat, but they are very thin and do not contour with the shape very well and water pools up in the rack louvers. I think i may be looking for a heavy canvas one, if anyone has a recommendation it would be greatly appreciated.

      ATV Snow Plow Review, Best ATV & UTV Snow Plows
      By Ajmboy
      So we are almost a month into winter and I've been so busy working on my house that up until today, I didn't realize that we just haven;t gotten any real snow yet to warrant putting the plow on my grizzly. So that got me thinking, what are the latest plows out there and what ATV plows are the best? I've got 2 snow plows for my grizzly, a quadboss pile driver atv plow set up and a snowsport ATV plow. They are both a bit dated now and I tend to stick with the snowsport due to ease of use and I just like it so much. So if you have a plow on your ATV, please let us know what it is and post a picture with your atv/plow would be awesome. Would also like to know what you like and dislike about it.
      This is back a while when I did a write up on these 2 plows.... in 2009 I got the snowsport and in 2012 I got the quadboss.
