Used a stethoscope and right side of valve cover was louder. I actually thought there might be an exhaust leak somewhere but could not find one. I ultimately resolve the ticking/clicking problem during by recent valve adjustment effort ... FYI, I don't think the problem was the valve clearances. During this effort, I disassembled the valve cover components including the two PAR reed valve assys, cleaned/soaked them with vinegar, and scrubbed with small parts cleaning brush ... all came out shiny clean. Note everything was covered in a thick/caked layer of black exhaust particles. Upon seeing this, my first thought was that the "metal reeds" could be sticking and or didn't close/seal flush with the body because of the particles. PS ... I also stripped and re-clearcoated the valve cover. ANYWAY, I have put 200 miles on the bike since then and there is no ticking/clicking ... yeah!
Maybe you can use a stethoscope to confirm the location.

But I believe you can plug the hole (there's a rubber hose connected to these) to see if the sound change. If I remember correctly, its a waste gas management system. So shouldn't affect engine function.

This should work. Thank you very much everyone i appreciate your help.
I put coil 1 on the 4th , the ticking is still there in the video.
Also there is that weird sound (like a zap) while the pump is turning on (injectors maybe?) , i haven't heard that sound in any videos of CBs. it's at 11 seconds, 1:50 ...
Thanks again.
