Would that be the big line that goes through the pass through in the back, or the little one? Why is there oil coming through that line? It's not a K&N, it looks pretty stock, with the white plastic, and no branding on it at all.

The big line is like a cars positive crankcase ventilation (PCV) for your bike. If your crankcase was sealed, pressure buildup as it heats would bust seals. Also, a little bit of cumbusted gas will always find there way past your rings. this will leave NOx in your system an if NOx gas is allowed to build up and churn with your oil then it breaks down the oil very quickly and is very acidic on the metal conponments. So the crank case has to breathe or the engine will not last long.

The little line is a vent from your fuel bowl. Most just vent to open air, but california models vent through a charcoal canister and any vapor that returns to liquid is stored in a reserve so the fuemes don't go into the air.
