every time i take my 130 sportster.the little rubber hose thats clamped between the manifold an exhaust keeps either getting a hole blown through it or melted.im just wondering what would be causing this there when u look into the jet pump it doesn't seem to be full of weeds an shit.is there any way to check if its getting clogged. an how do you check the circuit to see if thats clogged
