I have a 1994 CBR600F2. When I take off whether fast or slow, I am getting a clunking sound and as I speed up it gets faster and louder. If I let off the gas it seems to go away until I give it more gas. I can't hear it after reaching 45 to 50 MPH due to wind and road noise. Any Ideas where to start looking to find the Problem? I don't want to bring to a dealer as they are WAY too expesive. I am goint to order new sprockets and chain this winter any way, could this be the problem?

Yup, the chain could be clunking around if its night tightened correctly. does it feel like it rides ok despite the noise ?

 

It should be ok till you get your new chain, just make sure its adjusted correctly (adjust at the tightest spot on the chain) & lube it as well. Chains never stretch evenly & your hearing the tight/loose sections of the chain going over the sprockets.

 

Most likely the chain. Like what everyone else said, adjust it, give a good cleaning and lube job. It should hold on until you change it.
