[6pack] speedo opinions

[Jim Jones]

My speedometer is making a lot of noise (RMM-RMM-RMM) and the needle bounces around a 180 degree arc. I've lubed the cable so it turns freely. It was new one year ago. When I test the speedo using my adjustable speed drill it's quite silent. I've also tested it by having the drill turn the cable shaft on the dizzy end. It's quiet too.
   
  What in blazes am it missing here?!
