How do you change the oil in a 95 Honda fourtrax 300?

There is a drain plug on the bottom of the engine. You should be able to see it without removing any skid plates. The oil filter is on the right hand side of the fourwheeler, it is a round cover with three bolts in it. Watch out, I believe there is a spring behind the filter. I'm not sure how much oil it holds, but you can go to Honda.com and get the specs. for the machine.
