Smoking after Oil Change

Just changed the oil on my 04 Rhino....noticed that it is smoking a lot. I drained the oil and measured what I put in there to confirm that I did not overfill it.

Replace the oil and it still smokes. I think that I remember that it smoked quite a bit when I first bought it (used about a year ago). Could it be that it smoked less and less as the oil level dropped over the last year? I did not pay attention to how much came out when I originally drained it.

I did a compression test when I bought it and that was right up there at 170 or so. Should I do a leak down test? What does that tell me and what should be the spec for that? I cannot find any information in the Service Manual for a leak down test...

Thanks for the help...
