Yes this is what happens when you have a dry sump engine ( no oil pan) and emission hoses drawing crankcase gases and oil mist into the intake system. Once the airstream hits an area of low pressure ( low verlocity vaccum chamber) ie the airbox, the oil particles can drop and collect on the bottom of the air box. Harleys do this also, but you wouldn't know it because HJD put the emission lines directly into the intake ( read after the airbox) and the oil particles are burn't along with the fuel/air mix. This is not a problem, this is how stuff works in a dry sump motor. Talk to any race engine mechanic and they will confirm that this happens. Simply put vaccum sucks the crankcase vapors (oil) out and they end up in the airbox - consider it a part of normal service.

Well, not JUST a BRP thing......I had that happen a LOT with my Yamaha V-Star 1100. Good thing to note though, so we can keep cleaning it out befor it POURS oil when you open the Air Box

Or put in an oil catch can like Lamonster did. Looks like a pretty simple thing to do.

the can-am outlander does not have a dry sump system.It is a wet sump system.I have had more than my share of atv and cycles.I have never had a harley but have had honda,kawasaki,and most other jap bikes and never seen any of them put oil like a brp engine in the air box.they have had a light coating in them but the outlander has about an inch of oil in the air box.all that in 800 miles.
