Welcome to the org! My 05 doesnt make any noises that I am aware aside from the normal operation. I will have to pay closer attention.
Its kind of a "rumble" isn't it? Its normal.......my 14 and busa both do itThanks to all.....will work on a clip. If its normal for the Busa, great. Its not really loud, and not "sharp" like a metal/metal, or friction sound, but when you let out clutch you can feel a slight vibration that you dont with clutch in, and hear almost a "whir" or sound of rotation? Again all bikes make some noises, but always get worried when it happens with clutch engagement...
Resevoir appears full, bike moves away smooth and clean as clutch out gently, so "works" fine, but the sound made me nervous.
No prob...thats what we're here forRumble, that would be the word that I was looking for that eluded me! Not harsh mechanical noise, but a mild rumble, that seemed to lessen after a few miles...bike had been sitting at dealer for a few weeks when I bought it and this week was first run...tks
If the idle is a little low, it will make the noise worse since the engine will be idling rougher than normal.
