This happened a few weeks ago. It doesn't affect the performance of the speedo, but looks like a pimple on a pigs bum. Anyone had the same thing happen? No one seems to supply just the speedo face, but I don't want to throw away an otherwise sound instrument, and I'm not sure I have the capability to cut a replacement out of thin plastic. Maybe I should take it apart and remove the face completely....I know how fast I am going at certain revs in top gear. It would be cool to look at the guts working...
