ok so here it is, i talked to a mechanic and the second he heard it he told me it was the CCT and was just very loose. i want to do this myself because it doesnt sound like a very hard adjustment. i've looked in my manual and it doesnt straight up say "how to adjust CCT" so im kinda lost on where to adjust it. can someone send me a pic of where the adjustment is made? or describe where the adjuster is and how it is done? i would really like to do this tomorrow (march 4th) because it is my only day off. if anyone has the time, plz help. thanks in advance!

This is off a F4i but it is the same concept. There is a picture of how the cct goes installs in the manual if you have that. If not download it from http://www.cbrextreme.com/forum/cbr-600-f2/

Yeah there is no adjusting it. The oem cct's automatically adjust themselves. You can either buy a new oem cct or a manual one that you install and adjust once. Either way the sound will go away. With the manual cct, you don't have to worry about it breaking again as you will the oem. APE makes the manual and can be found on ebay for approx $50. I replaced mine with the APE 12,000 miles ago and haven't heard a noise since.

I'm glad you're not having to adjust your valves, as it is a job. I did it on my wifes last year. Here was the process that I did.

FIXED AND THE NOISE IS GONE!!!
i didnt order an oem cct or the APE manual cct. i just did some research on some other forums and found that people have converted their oem cct into a manual cct. i havent found any horror stories about doing this but overall it does the same thing as the APE manual cct. this was very easy to do and im very glad i found this. i will keep a very close eye and ear on it to make sure this $1.50 conversion doesnt end up costing me a motor. here is a copy and paste from another forum of what i did...
Honda Cam Chain Tensioner's
Yes they suck big time, but here is the $1.50 fix for the later Honda's, F3 and up. If your CCT has a plug (bolt) at the outer end remove it keeping the washer. Buy a 6x1x30mm bolt and matching nut. Double check the threads by placing the new and old bolt's threads against each other. They should nest together perfectly. Thread the nut on the bolt. Put on the washer you saved, and thread into the CCT. Gently (finger tip pressure only) rotate the bolt in until it makes contact with the piston. Holding the bolt with a wrench, tighten the nut against the CCT to lock it in place. Your CCT will now be silent.
Why does this fix work? The CCT in the Hondas does not have a ratcheting mechanism. It depends on a left handed threaded shaft that is spring loaded. Due to the locking pitch thread design, this shaft cannot back up. Sounds good so far? Unfortunately the shaft stays in one place so long that the constant vibration wears out the shaft or the nut that the shaft rides in. The shaft gets sloppy and does not exert enough pressure on the chain pad, so the chain starts to rattle at high RPM. The bolt fix exerts just enough pressure on the threaded shaft that it prevents the shaft from vibrating and backing up, thus eliminating the chain noise.
Yes you will have to adjust the bolt eventually, but so far I haven't had to. There is no data as to how long the time intervals are between adjustments. Hopefully this will not only save you money from a manual CCT or a new factory one @ about $50.
A million thanks to everyone for all your input and advice!!!
