While I'm always skeptical of internet troubleshooting, and I can't say for sure I hear it in the video, by your description it really does fit a cam chain tensioner problem. At least in early stages you may hear it at idle, and it becomes very prounounced in the 'approaching' 6000 RPM range, then quiets back down at higher engine speeds. Have you ridden it since removing and reinstalling the tensioner? As a temporary measure, you may want to try the method of 'manually adjusting' the automatic tensioner, just to see if it quiets it down.
