I have a 2013 V Star 950 with 8100 miles on it. There is an intermittent clicking noise underneath the seat. Does not occur until the bike warms up. May start clicking after 30 minutes or not until 2 hours or not at all. Never does it when the bike is cold. I turned off the engine, put it in neutral and coasted down hill. It clicks once with every revolution. Does it with the clutch engaged and disengaged. It is loud with the engine off. Has been doing this for about the last 1000 miles. Anyone experienced anything similar?
