My way is often very odd, so don't take my advice unless it jibes with your personality....
Remove the middle bolt to the ACCT, be careful, there's a spring inside there, just remove it carefully. Then remove the 2 bolts holding the ACCT to the cylinder, and very carefully pull the ACCT away from the cylinder without letting the insides touch anything on the way out.
Count the number of ridges or valleys that are exposed. Mine looked like this one, about 6-7 clicks exposed, meaning the chain is not terribly stretched. I have 13,000 miles and I am not going to replace the cam chain any time soon.

I would never take a bike to a dealer and ask "what should be done to this bike?", you are likely to get a bill for $2000.....
If you must take it to a dealer to have the valves adjusted....
ask for a leakdown test, and ask for a detailed explanation of where the leakdown is occurring if it in fact is leaking, if they can't ell you, they are not very good:
leak out of the intake area = intake valves
leak out of the exhaust = exhaust valves
leak out of the breather = rings
