Here’s an odd one for you. 2010 675. Finished up a weekend of track and bike ran well. As I was parking back into the garage at idle, heard a pretty loud “clunk” and rpm drop. In the video it happens in the first 5 seconds and last 5 seconds. Did an oil change afterwards with no glitter. Initial idea is to check the cam tension, and if not lose, going to recheck timing. Any other thoughts?
