I have had this issue before.
The speedo or tacho spindle pivot points need cleaning or oiling like a clock mechanism.
Take care not to contaminate the clock face when oiling .
The pivot below the coil springs and magnetic weight is difficult to reach.
I suggest spraying solvent 1st to clean then oil.
Depending on how dirty things are .
You can test using electric drill before rebuilding.
