Fazers don't have tappets, they have inverted bucket and shims. 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.
