I have read some threads on vibration and I have checked the wind screen for vib. I ride a 2002 busa with 24000km. The vibration starts at 4000km and worsens up to red line.I am used to runing gixxers as this is my first busa. The clutch also seems to be noisy in neutral when not engaged. I hope these characteristics for troubleshooting help because I refuse to ride a bike that is not up to standards. Any avise would greatly be appriciated.
