Cam chain tensioner (I think)
So just bought this bike. 2004 Zx-6r with 11k miles on it.
The valve train does seem slightly noisy when cold and quiets when warm. You can still hear it but it’s not as loud as when cold.
From what I’ve read I just need to replace the CCT. I have read mixed reviews on whether to buy manual or oem CCT.
I have no symptoms of bad timing (no backfiring). The valve train just seems slightly noisy.
Thought about changing oil to see if that helps as well. Welcome to any opinions.
I want to apologize in advance, I looked through the forums on this topic but just wanted to ask the question myself for peace of mind.
Thanks for any info!
Lots of things can make it appear "noisy"
You have given us zero to go on, but at 11,000 miles on a street bike it is pretty dman unlikely to be a cam chain tensioner issue
What information could I give you to better assist me?
I have listened to a lot of the YouTube videos where people post their bike idling and it sounds similar but not as intense.
All the comments on the videos say the issue is the CCT.
I appreciate you responding!
Noisy compared to what? Your last ZX6?
Just wondering what your last bike was and what you classify as noisy. There needs to be a point of reference in there somewhere.
Youtube videos taken with a phone and no mic are not a good point of reference.
If it ain't broke, don't fix it.
actual temp readings on the instrument cluster
What kind and viscosity of oil?
Are the sound deadening pads still inside the fairings and under the tank?
Does the noise get louder and quiter if you wack the throttle to say 6k from idle and let it drop back to idle on its own (ie...let go of the grip or slam it shut)
louder on the way up or the way down?
and just because a bunch of no brains on the internet claim they had some issue and "fixed" it doesn't really mean that was the issue nor that they fixed anything, 9 times out of 10 I would bet they fucked up something else........... I see it all day everyday where idiots try and fix things they were told (from the internet) how to fix and what was wrong only to wreck it and/or other shit on the way in and/or out
Are any of those people actual motorcycle technicians?................ I bet almost zero
Are any of them actually top notch ones?.................................... I bet almost zero
How many of them actually know more than they apsew? ............ I bet almost zero
How many are just regerjitating some bullshit they heard and took it as fact and haven't a fucking clue what the hell they are even talking about?............................................ ............................. I bet nearly all of them (the whole 1 person claimed something, 40 people repeat it and now everyone claims it is common and to be an expert falacy!)
Just started it.
It seems the noise decreases in noise just as fast if not faster than motor comes back to idle. Revving at about 130 degrees.
Honestly man it is FINE. Kawis tick. Could be an oil thing, and that idling isn't too hard on your motor.
1) Leave the CCT alone
2) Learn to do a valve clearance adjustment. MOST IMPORTANT SERVICE to do on any bike EVER (2nd to oil changes). You need some pretty awkward tools like long head hex bit (size 3) to undo the airbox from the frame, a tiny 3/8'' extension for the long head hex bit. A digital caliper to measure shims. A shim kit (60-80$)
And roughly 1-7 days of SERIOUS attention.
Valve adjustments are most important in the first 11k miles because the motor wears its clearances more than the following 24k, 36k mile clearance checks. If you adjust it once you may not ever need to adjust it again till it blows.....
The person who sold you the bike either knew the clearance check was due and he can no longer rip the bike risking a motor failure or he checked the clearances, and realized that he can no longer rip the bike risking a motor failure................
It's rewarding man. If you never pulled the valve cover off a motorcycle before, it may be DAUNTING/DIFFICULT. But if you pay careful attention, stop fapping, and just do it carefully, it is very rewarding .
