honda cbr 600 (fy) ticking noise

[muj200]

hi,

is there anyone out there with any ideas? my year 2000 cbr 600 fy has developed a ticking / vibrating noise which comes from the right hand side of the engine. this noise can be heard on tick over and when the bike is running at a steady rpm (3000ish). the bike is mint and has a full service history having covered 16500mls.

at first i thought it was the shims which needed doing as honda say they due at between 16-21k but im told that its totally the wrong sound for this. the bike rides and handles as it has always done - 100% it has no loss of power and it does not consume any oil. i cannot feel the ticking when i touch the head.

any ideas? its puzzled many.

thanks.

muj.

Not sure if these engines have gear driven cams or chain.If its chain driven it could be this ?

Hi Muj

My bikes doing exactly the same. Ive been thrawling through the forums and think this is the most likely answer:

"The cam chain tensioner needs to be replaced. It is ~$50 and a half hour of your time tops on an F3. I went through a couple of them on my F3."

Ill be nipping down to the mechanics this weekend to get his advice.

guys,

thanks very much for your help. the cams are chain driven. ive been researching this problem too. it turns out that it is the cam chain tensioner and its a very common fault.

thanks again.
