I have a 900 RMK 2005. When I started it up the other day to move it off the trailer I saw a bit of oil dripping out of the exhaust. It left a small amount about 3-4 Tablespoons. I started it up and moved over a few feet just to make sure it was from the sled and same thing? Anyone had a similar problem, is that common with these? I just bought it and had it in for service and they didn't say anything?
