I searched around and did not find any references to someone else doing this, so I thought I would post it up. :thumbup:
I have an 08 GS/RS and over the course of my ownership I have been bothered by periodic oil leaks from the air box. I've read the different threads about the cause and solutions available. However, I didn't want to do a catch bottle. It just didn't seem like an elegant solution. Functional, but not quite what I was looking for. I don't care about keeping or discarding the breather line into the air box, since my state does not have annual inspections.
So in short, I took my years or wrenching on motorcycles and put it to work here. What I did was to run about 3' of hose from the crankcase breather port up and along the side of the engine. Up to the area of the instrument cluster and capped it off with a Uni crankcase vent filter. I then zip tied it to hold it in place. That also keeps it away from the hot exhaust. I then capped off the air box input port.
My theory being that the extra distance and elevation would negate the oil being blown up and out of the vent tube with gravity returning the oil back to where it belongs.
After testing, the answer is yes, it works just fine. No oil residue at all and no catch bottle to worry about. The filter is serviceable, but only needs to be washed in soap and water infrequently and is installed dry, so it all should last the life of the machine with virtually no servicing required.
Cost to me was free 99, but that's because I had everything laying around. However, if you were to buy everything I estimate cost would be around $10 or less, if you went with a cheaper filter.
