I have a 1981 Goldwing that the valve stem broke on rear wheel can I break the bead on the rear rim and replace it with out taking wheel off. If so how I seen where Puc said something about using c-clamps . Do you put pieces of wood to protect the tire? I think I included pictures of my stable. Blond 83 Venture Royal, Blue 83 Venture, and the 81 Goldwing I made my own Voyager kit for the wife.
