Clutch works fine 
Easy to pull and does not slipp. I'm leaning towards the tick coming from the valvetrain. Having done ridden the bike a ton this summer maaaaany miles without a hickup or anything getting worse.It ticked much louder before I did the valves and balancer earlier in the summer. So maybe I will just live with it if it does not get better after a second valve check.

Any thoughts on what to look for?
Clutch starter parts are quiet when running and sitting, meaning not engaged. Starter would semi-catch, or spin the starter motor up not catching at all. Starts right up, don't need to look there.
Valve tick is a tight valve lash. Kind of look at it like this:
Say the lash calls for .002". If using the go-no go system, an .003" won't fit. When I say I set mine loose, I have zero drag on my feeler blades. If it calls for .002, then I'm loose, so my blades return back in there cage, as if brand new.
Because I'm setting it more like .0029999987. If you're dragging that feeler, it's not at .002, it's more like .0019999956. You think it's loose, but you just took up the slack the oil rides in the rocker shaft. That kind of squeeze under .002, is push the oil out somewhere.
So a loose gap, can't slide a .003, that's going to quiet things down some, if not peace of mind knowing you're not burning out a valve procrastinating adding more miles.

Checked the valves. Exhaust valves was a bit loose on both sides. Camchain can be rocked from side to side but not up (with flywheel on "T"). Exhaust gaskets changed.
Camchain with CCT loose on "T":
Engine noise now:

Pictures of the cam area. Seems to be getting enough oil
