Question Follow that hose!

I have noticed that my 919 has been leaving a small oil spot about the size of a quarter in the parking lot at work. I looked today and the oil is coming from the largest drain tube which comes out just in front of the swing arm mount on the left side of the bike. I followed the hose as far as I could without pulling covers, etc. and it looks like it goes up toward the top of the engine somewhere. Does anyone know where this hose goes? I'm concerned because it appears to be engine oil and also because I'm leaving spots on by bosses new concrete pad. The other thing that is odd is that it doesn't leak a drop in my garage. Could it be from sitting in the sun all day? Thanks for any ideas you might have.

Are you sure your not dripping hot Chain oil/Lube from the drive sprocket cover.
It could be running down the hose looking like it's coming from that.

Pull the cover & clean out the build up.

SORRY FOR THE CONFUSION. IT'S ON THE RIGHT SIDE OF THE BIKE.

Yeah that's normal. I always thought it was vapor from the tank.

You bike does not want to be at work, parked in a strange place. It is begging you to ride it or at least leave it at home in the comfy garage. This is not unusual at the beginning of the season. Just smack it around a little and tell it to straighten up, that should solve your problem.

Knees in the breeze!

I had this exact issue--chain lube buildup behind my 919's sprocket cover started to liquefy in the heat, and left spots when I parked at work. I was worried that I had an oil leak, but when I pulled the sprocket cover off I found merely a buildup of goo. A thorough cleaning, and all was well.

Is your air filter over-oiled? I've done that mistakenly and had oil residue bleed off through the drain tube.
