Oil change/Radiator fluid

What’s goin’ on guys. I’m a proud new owner of a 2008 Sportsman 800 and I wanted to do some simple maintenance. Not too knowledgeable about the motor yet but my questions are:
How many oil drain plugs are on the 800? 1 or 2?
Once I fill the radiator, how much fluid should be in the reservoir on the left side?
Any recommendations would be appreciated. Thank you
