I am working on a friends 07 gs500f and it is making a ticking knocking type noise at idle from the two line coming out the jug under the exaust. If i pinch the rubber part of the lines the noise stops. The two line go two a valve that I think make the fuel go to the carbs when back pressure is applied to the valve. Is that valve bad or is it something my friend is going to have to listen to.
