I bought my first bike last year, a Vulcan 800, and I discovered a tube dragging when I got home after my first day out this year. I called the guy I bought it from, and he said he thought--from the sound of it--that it was the overflow tube for the fuel tank. I just looked it up on Kawi's web site, and that does indeed appear to be the case. The guy said he thought it should run around the tank and go back in somewhere, but I couldn't find anything on their site saying one thing or the other. Does anyone know whether the drain tube is supposed to connect back into the tank?
