A well-tuned engine with good close carb sync often significantly reduces cam chain noise.
Good Luck!

To set it they say with the engine off screw it in until you feel the rod just touch the chain or the chain guide ( you do it by feel) then back it off a quarter turn.
I did that and I still had some noise so I also loosen the lock nut with the engine running and adjust it by small increments in or out based on the sound.
Be careful you can set it too tight. I set it too tight and it hardly made any noise but the bike felt weird until I backed it off a bit. Seemed harder to start...
Once you have it set you don't have to mess with it for a while unless your cam chain starts making noise.
I think I read on the motordr site for KZP's that you can also weld a small nut on the stock tensioner rod to have more length on the rod and the spring will push the nut against the cam guides.
They do all say this is a temporary fix and if your cam chain is worn or if the guides are grooved it's only going to get worse.
The worst part of the install was R&R'ing the carbs.
Easy to take off a major pain to replace.
Check out www.600rr.net/vb/showthread.php?t=135386
this is the section on tuning the tensioner with the engine running.....
5. “Now the fun part...tuning it. Tighten the big middle bolt on the tensioner until it is hand tight. You feel some pressure on the chain then back it out a 1/4 of a turn. Start the bike and give it a few revs to where you were hearing the chain rattle, most likely between 4000-6000 RPM. Turn off the bike. Tighten the tensioner bolt in small increments and retest until your rattle is gone. Both the bolt and lock-nut are 5/8 inch. You don't want it too tight, so a little rattle is ok. A little loose is better than too tight. After you find the sweet spot make sure you remember to tighten the lock-nut as well.†I had to actually go for a test ride to make sure. I just left the fairing off, went for a ride, came back and decided to tighten it a little more. .......
