2016 Polaris Sportsman 570 Overheat Problem

I recently bought this bike 2 months ago, and have fell in love with it. I've already replaced the front right axle on it (my own fault for where I was going), but otherwise have had no problems with it.

Recently, after riding for about 2-3 minutes the Over Temperature light will come on, the bike will go into its "Engine Saving Mode", and then the light will start flashing and die. When I feel the sides of the motor, it is not very hot at all and should not be enough to be causing it to shut off. I checked fuses and relays along with the radiator to see if it was clogged, and the fluids are all in check as well. I don't really know what else to check, and any help would be greatly appreciated.

Yes, and will stay on as long as you have the key on. I let it run for 3 minutes after the bike died, and never shut off on its own.

But after I turned the key off and let it sit for 10 minutes, I could run the fourwheeler for another 2-3 minutes before it would do the same thing again.

I don't know these engines at all really but all that comes to mind for that issue generally would be
1. A temp sensor fault
2. Thermostat stuck closed
3. Failed water pump

you may have air in the anti freeze causing improper reading in the temp. Raise the front of the machine 12+" and burp the coolant to make sure that all the air is out of the system.

I did this and have run it up and down the road multiple times without it saying its overheated. Seems to have fixed it, thank you.
