If I'm to believe what I'm reading in other threads on this forum. This particular model 2014 Harley Heritage is of a number of models that although have spokes, does in fact have a tubeless tire. Something about a liner is in place, that is recommended to be replaced with each tire change. Which all brings me back to my original question. if the trouble on this tire is just the Valve Stem, is replacement of this valve stem possible. Via the ways I've seen online, breaking the seal of the tire to the rim, gaining access to the back of the stem valve, removing it and replacing it.
