My Vulcan 900 has one annoying feature: A light tapping from the front cylinder at tickover and light throttle openings, when warm. You tube has a posting where almost every owner says their 900 also taps, and say it is a feature. I suspect the camchain tensioner is stuck. When I did the valves the guy at my local Kawasaki dealer said don't worry it will adjust itself, but what if it is stuck? Has anyone removed theirs and reset it? Is there another reason for the tapping?
