I recently purchased an 04 Bearcat WT with just over 500 miles on it. I took it out for the first time today and when I trailered it I noticed that quite a bit of chain case oil had leaked out on to my trailer (it didn't appear to be leaking prior to this trip). It would appear that it started leaking shortly before, during or after I trailered it. I checked the oil and it was at the "Add" level. I put about 10-15 miles on it pulling a FishTrap portable ice fishing shelter. I looked in the manual and it says "If excessive oil deposits are noticed, take the snowmobile to an authorized Arctic Cat Snowmobile dealer for service." I'm not a gear head, I'm an ice-fisherman so pardon the naivety of my questions. First, what is "excessive oil deposits?" Second, what would cause the oil to leak? Third, how concerned should I be about this (is this more that a "just add more oil" remedy?)? Thanks for the info!
