Default 2014 Honda 420 oil in air box

I have a 2014 Honda rancher, I pulled my cap at the bottom of my air box to check the snorkel and about a quart of motor oil came out. The ATV was running perfectly fine, no ringing from the piston rings or knocking and not low on power though it was on its side for a bit. Could that have caused oil to go into the air box? Any other suggestions?

The breather system is fairly good at keeping the oil in the sump, rather than transferring it to the airbox, but a bike on it's side may do this, particularly if the engine was still running when it fell over.

I would run it for a while and see if any more oil gets in there. An engine which has low compression due to worn rings will pump more oil vapour into the box, but you will also get higher oil consumption and blue smoke from the exhaust.
