I stopped by a friends house today and he wanted to ride my Road Glide. I hopped on his 09 Ultra and there we went. I had barely pulled out of his driveway when I started hearing something loose, a metallic sound. Pulled over when I could and got to looking and his rear pulley was broke. The inner rim was totally broken off the pulley, the belt had tracked inward about 3/4" and the pulley rim had beat the heck out of his wheel rim. Oh yeah, I did turn his stereo off before we left. He said he never heard anything. Has this happened to anyone else? Called the shop and they haven't heard of this either. We will see what they say Saturday when we take it in.
