I will come back to you with the method for adjusting this.
If you set the power valve to open at a higher rpm or restrict the vavle from opening to its maximum then your problem will be solved.
If you do the latter though you will definately lose your power at high rpm.

SOURCE: adjustment of valves
A service manual is a valuable tool with an aging bike. I suggest the dealer/mfr. or Clymer books. In the meantime, go to the library reference section...646 stacks should have what you need.

Absolutly.Especially if the noise reduces as the engine reaches operating temp.It could also be cam chain is a bit loose.This would typically not reduce in noise as the engine warms up.Valves should be checked every 10,000kms as a general rule.Use a large phillips screwdriver & place it on the rocker cover & you ear on the handle(in several places with engine running)this will help you to narrow the noise down.I use a mechanics stethascope which are generally available from your local tool shop. Thay are not too expensive,they work better than a screwdriver,and can be vrry usefull for finding all sorts of unusual noises. Hope this was helpfull

Try checking your valve stem seal or see if your exhaust pipe blows white-bluish smoke when you up the rev for the oil leak. If it does then have it fixed or you can try to use oil sealer additives for not so badly damaged seals or even piston rings.
How often did you change the oil, have you ever use engine or lifter flush additive?
Go to your local car/motorcycle shop look for an engine flush/lifter flush additives, put it into your oil, ride for about at least 60 minutes, change the oil and filter, ride again for about 2 weeks (200-300km) then use the same additives again, change your oil and filter again,put in fresh oil and filter and that should give your a relieve from the noise tappet ticking.
