I have a Kawasaki Vulcan EN500, today I was out riding and it started kind of hesitating. When I stopped at a red light the bike stalled when I tried to take off. It ran OK at speed, but tried to stall at all lights. When I got home I began checking it over, I found a clear fuel line, it appeared to connect between the carbs, and fuel was coming out of it. I´m not sure where it connects, but hope that someone has an idea.
