Hi guys

Looking for some advice on an 03 CBR900RR I recently acquired. It seems to make a rapid tapping noise from the engine. I spoke to the Honda 'master mechanic' and he assured me it was the air intake system opening and closing, and totally normal... it jus seems a little loud and a bit unsettling

Any thoughts, advice, reassurance would be appreciated!

ive got something similiar on my cbr1000rr its been into ecosse and they coudnt fint anything wrong it starts when the bikes warmed up and sitting at idle then disappears when you raise the revs

Ive heard of a few people complaining about the same issue.Have you tried some of the forums for the bike as these guys usually will give you a better idea or


You could always buy a Ducati......As if its not rattling its head off it not working right

Cam chain tensioner.

Get it changed asap.

The one on my old CBr600f was made of cheeze.

Best bet is to swing past a bike shop and have a mechanic confirm, but it is an easy replacement job.

Thanks for all your help - will investigate some more
