The chain is stretched enough that I'm out of available range on the swingarm to adjust it and the links are all sticking, and its got at least 2" of slack in it. It was in pretty bad shape when I got the bike. Im 90% sure its the chain making that noise because it increases with the speed of the bike but does not match the speed of the more rapid rotation of the wheels. The noise doesn't really match anything else and its mostly just on throttle.Ok I watched the video
the womp womp womp sound was scary. almost as much as the traffic.
