At certain RPM's you may notice a vibration only to have it go away with a couple 100 more RPMs. These are normal for most bikes and are harmonic in nature. There's absolutely nothing a dealer can do for you except take your money. Remember, these bikes can all be taken to a track and thrashed and perform all day long -- unlike 95% of cars on the road that are built for comfort. I'd only take the bike to be checked out if you notice a noise that you know isn't right or the vibration gets worse with speed or higher RPMs.

Well, its definetly not a vibration and it only happens at those certain RPMs. But when you hear it, its sooo loud and irritating that you think everyone within a block is going to hear it and look at you funny. It almost sounds like those kids that have the playing cards stuck in the wheels of their pedal bikes, know what i mean?

whoah, hold the band-wagon. My bike ('03 CBR 600 RR) has been doing this too, at certain rpms I can hear it better, but its there almost the whole time. It sounds a lot like an old car that is semi-out of oil. I just tried overfilling my oil (tell me I did bad :S) and it seemed like it helped a little bit... I got to thinking and when I got the bike (6,250 miles) it wasnt this loud. the stealership told me the 6,000 service had just been done and they took awhile fooling around w/ the coolant system (coolant hose later came off, lol the main one on the left side hahahah because they forgot to clamp it... doh) and the oil and stuff. Anyways... my question is... could it be because of old oil? cause changing the oil would be a snap, specially if I know its going to get rid of my anoying sound... mine doesnt sound out of place, it just sounds kinda low on oil, but its definately not. Im hoping maybe yours is the same addict?? to go w/ my question... any pushes/prods towards a good oil filter for this bike? and is valvoline 4 stroke motorcycle oil (NEW! High temperature performance, superior wet clutch protection... sae 10w40) gonna get the job done?

100% its your cam chain tensioners, the o.e. ones are known to give up at around 5k miles on cbr6's. Get it replaced with an o.e. or manual one. Its not expensive and you should be able to fit it yourself if your anyway competent with a spanner.

My 93 just started making that noise yesterday when i was riding i thought it might be the cam chain, its more noticeable from the right side on the engine but still only happens at about 5500 to 7500rpm i juust replaced my oil about 3 weeks ago and im was planning on drianing my coolant and replacing that too,

i was wondering for this problem are you guys talking about replacing the chain or the tensiorer or both

My first post becasue i came looking for answers to my problem

I was having the same noise as a lot of you guys said, around the 5500-7000 RPM range. mostly being on the ride side of the motor. I took it to my local dealer and they just stuck their head down by it and listened for a bit and suggested that it could be a Cam chain tensioner like you guys have been saying.

Im going to pay $30 for them to take a look at it on thursday. If it is i will buy a new one and install it myself.
I will let you guys know if thats the problem.
