First Oil Change

I have a 2015 Foreman 500 TRX500FM2 and the first oil change is due. Called dealer today and they want $170 to change oil & filter, check & adjust valves, clean air filter, check differentials, and pretty much make sure everything is good to go. I’m not hearing anything unusual while motor running but this is my first atv and I’m not too sure if I need all this done at this time. Is this oil change something I could do my self and get valves checked next oil change? Or should I get things checked out now? I will be out of warrenty in April 2016. I don’t ride enough to get 600 miles on it by then for the next due oil change. Sorry for being long, any thoughts are appreciated.
Thanks
