Guys, I've got a Dunlop E3 on the front of my 2003 GL1800. At really low speeds, less than 10 MPH, the frontend feel loose and the handlebars will shake enough to make my mirrors vibrate. It's worse two up as it lightens the frontend. Goes away above 10 MPH. Had my steering head bearing torque checked. It's fine. Got to looking at the tire and I can see "ridges" just left of the center of the tire at certain locations. Could I have a belt that's failing in the tire carcass?
