The recommended oil is Honda GN4 10W-40. Like Pain stated, most automotive oils have friction modifiers that will cause the clutch to slip.

Let me know if your ATV is 2wd or 4wd and I will post a link to an owner's manual that you can download.
I've used diesel to flush them out. Just drain the old oil out and pour diesel in and pick the front end and back end up and shake it around a little and drain the diesel back out. Let it drain for a long time, so all the diesel will drain out. Then put the new oil in it.
