Right..... I bought myself a 1995 600f about a month ago. It's my first sports bike and I spent the first couple of weeks smiling ear to ear at the sound of the thing! it's pretty much as standard except an after market carbon can, and mini indicators! to the point...... once the initial novelty wore off, I started to get used to the massive noise the can produces and started to notice a strange whirring noise from down below. Its hard to make a noise in a forum but it sounds sort of like soft metal-metal abrasion kind of noise!? However, this is only present when i roll on the throttle and not when moving off throttle.

I am concerned that it could be some sort of engine wear? or could it just be the chain needs to be a bit tighter and is sounding it's protest!?! The oil levels are good, the chain is well lubed and the bike has only done 18,000 miles and is very clean.

Has anyone got any experience with such a noise, or is it just the noise a cbr makes (I have not ridden another to check)

Pardon my naiveity

Cherrs guys
