I have a 2020 TriGlide. We were riding and smelled burning rubber. Pulled over to see my breather hose burning like a fuse . Snuffed it out with a rag. I did just fill up, but no different than I usually do. Has this ever happened to anyone? Any mods to the bike have all been done by HD. No mod to breather hose that I aware of. I bought t(e bike new 2 years age and have 8k miles.
