I started smelling what definitely smelled like oil. I looked up, and noticed a blue haze in the air. I ran over to the corner where the compressor lives, and saw it spewing an oil mist out of where the oil cap should have been. I quickly shut it off, and said a few very choice words. EVERYTHING is covered in oil. My motorcycle, my spare engine, the compressor, the wall, the floor, everything.
I filled the oil back up on the compressor and secured the cap. I wiped up the largest part of the mess, and hosed down the brakes on the motorcycle with brake cleaner to get the oil off the discs.
As for the rest of it - I guess the bike is in for a good soapy cleaning this spring. The windshield is absolutely covered in oil, as is the fairing and the front half of the bike. I'm just leaving the spare engine covered in oil - it will probably help with corrosion prevention.

I think I'm going to safety wire that cap in place.
