Speedometer Repair

[Kube]

You can certainly attempt to repair this yourself. A thorough cleaning and light oiling often do the trick.
As an "option" I'd suggest sending it to a friend of mine, Mike Blaisdell. He does this repair professionally. He's a very ethical fellow and does great work. He also does it in a very timely fashion. A typical "rebuild" with calibration is about $100.
