| Not sure what it is, and it doesnt do it all the time, but usually at the top end of any gear, or a hard rev, you can hear a slight knock. Does it when it is hot or cold, but it is so inconsistant that I cant figure out what it is. The bike has been well maintananced since it was new, and this isnt the original top end from what I was told. You almost cant hear it unless you are listening for it. Any ideas or suggestions? The bike has stock gearing and jetting, PCII silencer and FMF Gold pipe and Boyeson reeds Thanks guys Last edited by Nosdog3; 10-22-2004 at 09:15 AM. |
