Needs valve set or CCT?

Default Needs valve set or CCT?

Hey, I realize there a bunch of threads on the cam chain tensioner and from what I have gathered you can usually hear it at a specified RPM.

I got my bike about a month ago and at certain RPM's it would do a vibrating noise like a bolt is extremely loose, making me suspect cam chain tensioner.
Last night I pulled up to the garage and it was making the sound at idle, not as prominent as when riding it though.
Its an 04 CBR600F4i with 11,000kms or about 7,000 miles.
Just wondering if anyone has any insight as to what it may be aside from the tensioner.

More than likely it's your tensioner. Change it. If the noise persists then you know it's something else, but my money is on the CCTL.

I bought a 02 f4i last month with 1600 miles. It had a vibration noise around 5k rpm. When it hit around 1800 miles I started getting the cctl rattle. I have about 2400 miles now and I just changed the cctl today. The rattle is gone but I still have the vibration sound so I'm in the same situation as you.
