Unfortunately the video doesn't quite capture the nuances of the sound, but does well enough. If it's not the valves (or maybe they were off and I didn't fix them?) what is the source of this sound?

Engine noise got loud
Since I bought the bike three months ago the top end has always been clicky, from what I understood my valves needed some checking. I've been putting it off until I had some downtime but yesterday I noticed that the noise increased dramatically without any rhyme or reason. So, today I got at the valves to find they were mostly in spec and a few were tightened up a tiny bit. I reassembled and found the noise to be exactly the same.

I'd check the cam chain tensioner. Put the engine at 1-4 T with the valve cover off and remove it from the bike. A paint dot on the cam chain and cam sprocket will help you identify if the cams jump time while the tensioner is out. There is a rebuild tutorial posted by bwinger, as linked on Basscliff's website.
Good luckEd
