I have a 2008 Road King with 13k miles and I started to get a noise whenever I roll the bike backwards in neutral. It sounds like it coming from the transmission cover area, but could be from somewhere else. It sounds like a a loose chain on a sprocket and only happen in reverse when the bike is cold or hot. Just got the bike back from the dealer who had it on a dyno to install a Super Tuner for another problem all together. Thanks for any help on this issue.
