My bike have the same vibration, probably the sound/vibration come from the clutch cable. When the vibration starts touch the cable, to check if really come from him

That bike is a XJ6N (your FZ6R).
I know that guy, he always do movies like that (insane ride...looking for death?).

For me U$70 is to much expansive just to adjust the speedo!hehe Yes, im stingy!:D:D
But, the speedo sensor isn't in the front sprocket?
Changing the rear one, the front still rotating normally and the sensor will not detect any diference.
I don´t know if my thinking is clear...i hope so!
