2012 Sportsman 500 HO

I am new to this forum. I personally ride Can Ams but I bought my wife a Sportsman 500 new back in 2012 which has been a good machine for her. It still only has about 600 miles on it and I had the dealer do the previous services on it but now I am going to start servicing it as needed so I came here hoping to get some tips and pointers as I go. Thanks
