You’re right TennX. Buzzing is a much better description.
Anyway, This morning I removed the housing and installed rubber O-rings where the 5 top screws are.
I’d say that the buzzing is 90% gone now.
I know I read something about the actually speedometer head to fix the other 10% but now I’m trying to find a thread with and explanation for dummies (me).
Any easy way to search google is ...your key words followed by VTXOA
