As with all bucket and shims valves the clearances get tighter not looser, in use unless you've got a serious lack of oil problem and the cam have worn, again very unlikely. You don't want an utterly silent top end, this will ultimately burn out you valve seats if allowed to run tight i.e. below the min spec/clearance.
Fazers rarely need much adjustment, most don't need touching until 50k plus. It's fairly straight forward to check, if you know what you're doing and have all the tools that is. If any are tight it's a 'cams off/out job.
I'll refer you to the answer I gave you on 5 Mar. If it's not that it will very likely be some other item that now either gone brittle or touching the frame/firing etc. Another big and difficult to find (if you don't know what you're looking for) is the H1 blub cover in the headlight and/or the mountings for the headlight unit and clocks, same for the radiator/fan mounts. All will vibrate once the mountings become brittle/worn.
The noise is definitely from the top end of the engine, we both took turns on the throttle to enhance the sound so the other could check all around it and we both came to the same conclusion.
If truth be told it's not a job that I would attempt, I would let people who know what they're doing sort it out.
As for the H1 bulb, I did a post on here years ago about that vibrating. I found that wrapping self amalgamating tape around the bulb where it rattles on the headlight casing sorted that out.
Back to my question though, does this need attention sooner rather than later? Is it hurting the bike in any way, rather than just irritating the hell out of me?
When I replaced the clutch I changed the oil and I put exactly 2.7 litres in due to my oil window being permanently blacked out, but the oil is changed every 4000 miles with the same fully synthetic oil I've been using for years now.
