If your bike is like mine, that gizmo is a crankcase rebreather/capture system.  It pulls crankcase fumes from the case, and routes them into the air cleaner assembly.  The reservoir under your battery box is to capture the condensed stuff that won't go into the engine.  Every once in a while, you are recommended to open up the drain, let all the wet stuff drain out, and then plug it back in again.  I can't believe leaving that open would bother the engine all that much.
