Thanks! much appreciated.

 

I have a 2000 cbr600f4 and i was wondering if this could be the same for y my bike as well but my bike doesn't start making any noise until it is warmed up. Then after that i am able to rev the engine above about 3500 rpm and then i cant hear the noise any more?

 

bought '93 cbr a week ago and the guy said it had a rattle that 3 mechanics couldn't figure out... after finding this thread, a $50 manual cct off ebay and a beers worth of work the sound was completely gone. Thanks alot for this post!

 

I had my racer fairings off to change oil anyway so I put mine on. The actual removing of the old and installing of the new took less than five minutes. The hardest part was removing the two bolts that hold the clutch cable bracket for easier access.

 

So I just bought a '91 600f2 and have been going through it to clean it up. it's in pretty good shape physically but it doesnt like to idle. at first i thought it was a clogged jet since it had been sitting for just over a year, so i took the carbs off and cleaned them up. none of the jets were clogged and everything seemed to be in good working order. then i decided to double check the cam timing and the exhaust cam appeared to be off by a tooth, so i corrected it and put it back together. didnt fix a thing. i took it apart again and it looks like it is off again. the cams are in time with each other but not with the crank. figuring that it had skipped a tooth again. i attempted to correct it once more but i discovered that it was in fact in time (i tried adjusting the chain by a tooth again but it only made it worse). i put the cams back to their original position and rotated the engine once by hand to seat everything and im noticing that with the timing mark aligned with the index mark on the case causes the timing marks on the cams to appear slightly off. i rotated the engine again, this time lining up the cams first and then checking where the mark on the crank was. it is definitely passed the index mark but not by a whole tooth. my guess is the chain is stretched but i cant find a spec for it anywhere. after reading about how bad the hydraulic tensioners are on these bikes i will definitely be replacing it but since im short on cash i was hoping to be able to determine whether or not the chain is in fact stretched before i replace that as well. does anyone know a spec for measuring pin distance on these bikes? the bike has 67k miles on it so i should replace it anyway but i dont have the money right now and this bike is my only transportation. thanks in advance for any help!

 

Can anyone confirm this is correct? I.e. adjusting the CCT whilst the engine is running?

 

That's how I did it. Back it out until it rattles and then tighten until it stops and then a 1/4 turn.

 

Okay, so I think I just suffered a case of the CCT-rattling y'all been talking about. Today there were a new rattling sound when I started the bike after having taken a riding break for like an hour. It was present at idling in neutral gear but disappeared after 30 seconds or so. Having read about the problem I have already got an APE that I haven't installed but I guess now is the time to do it. Since I am a complete moron unless I have visual reference I would ask some man (or woman) of mercy to upload some pictures or videos that could help me out. The old ones in this thread seems to have been removed. Thanks, my extended biker family!

 

Somewhere here I saw just the thing you're looking for. You should search some more in the Tech section. It's incredibly easy to do. If you still have the instructions that came with your CCT you'll see just how easy it is.

 

Does anyone know where I can source one of these CCT's in the UK. I would prefer not to use Ebay but if thats my only option then fine.

Many thanks.
