It's all out there on the interweb... sometimes you just have to dig.

So, it appears the F800 motors do not vent directly out of the crankcase. Rather the crankcase vents somehow through an internal path and ultimately out of valve cover (#3 in drawing). The valve cover connects a crankcase breather hose (#2 in drawing) to the bottom of the airbox.
