Knock from carbs

So not sure what this could be. I have been trying to trace down a knocking noise i have been hearing. The bike has been running completely normal. I used a screwdriver and tried to track down the noise but nothing stood out.

today while warming it up for my ride home( I know i shouldnt be riding it but i have to right now) i listened and it sounds like its coming from the carbs. the screwdriver didnt indicate this, but just by earshot it seems to be the source.

When i got home the knock was louder and seemed like it moved to above the goats belly.

I havent got around to checking to oil yet due to work schedule. Is there anything you guys can think of first or is that the next step.Thanks Mick

sounds more like the rear Automatic Cam Chain Tensioner (ACCT)... search "The Grambo Trick" to diagnose this as the problem.. if it is, get a set of manual cam chain tensioners (MCCT) from TOC Manufacturing
