Just finished up. Glad I did, too. There was a tiny amount of residue in the screen, but basically it was very clean. However, the oil was black, which kinda surprised me since the UTV only has 14.6 hours on it. I hope it's not a bad sign. This was a demonstrator model, so maybe that's why it looked so dark? I don't know what quality of oil is used by the manufacturer, either.
