Looking at a used Yamaha Rhino

It turned out the rings were close to lined up and the oil ring had collasped. After honing and getting everything ready to put back together I had received the wrong ring set (was shipped .50 over sized). I got the shop to overnight the correct ones but that was still a couple of days since I was working on the weekend. Fast forward to present and I just got it reassembled last weekend and have put a few miles on it so far. While it was apart I decided I didn't like the faded green paint. Not being a hunter or a need for a greenish vehicle I changed the color with Krylon fusion paint. Sunbeam/Safety Yellow. Here are some pics of the new color.

Mazdaparts, just my 2 cents. Changing the oil would not collapse the oil ring.
Was the oil over filled? Oil picked up by the PCV system would induce engine smoke.
Anyway, at the cost of our toys, oil analysis is essential. I have my oil checked by a company that sends the sample bottle, return mailing tube and analysis of everything in the fluid including concentrations and possible source. For $20! PM me if anyone wants the info. Joe
They test any fluids.
