I bought a 07 919 a couple months ago, and it's the first bike I've owned that was made after the 70's, so it's a whole new world of bike for me. I went to change the oil today and noticed this tube hanging down above my exhaust pipes with what appears (from sight and smell) to be gas fumes coming out. There's three tubes in this image the one in the foreground, which given the bracket that seems to be holding in the place it is I haven't worried about since I got the bike (maybe it's out of place too?), but today was the first day I have noticed these two other tubes, specifically the one with the visibly wet tip in the picture. I've looked around and can't really figure out what is going on here and have tried to find diagrams of where this is supposed to be and can't. It seems that when I crank the bike the fumes stop, and I'm getting no warning lights on the bike. Help?
