Re: 01' R1 Top end Rattle...
Nice R1! I had a 01 that was a POS when I bought it and I did a rebuild, but yours is spectacular. CCTs were one of the things I added during the build. There's a good chance that's whats causing the noise. Also, if you haven't, check your valve clearances. If I remember correctly that was like a 24k mile service.
