Re: Three lines in front of rear shock
the 2 of them yes, they hang through the little opening in the bottom of the fairing. the fuel line is the overflow (if you have a deent amount of fuel in the tank and you lift the tank back it will leak) and the coolant is the overflow for when you overheat and the coolant boils out of the overflow tank. no idea what the 3rd line you have is though, check around under the tank (on the fuel pump) to see if any spots are missing the line that should be attached there.
if you can't convince them, confuse them.
