wavy rotors

[RobertWichert]

I would say "probably not" to this, but it's conceivable, I guess. Testing would reveal the right answer. "One test is worth a thousand opinions". I did like the response about cross-drilling being similar. That's a good point. Robert Wichert P.Eng.

My odometer has stopped working. While this obviously means less miles on the bike, it makes it difficult to keep track of when maintenance is needed. The speedometer works fine. The problem appears to stem from the trip odometer. When it reaches "0" tenths of a mile it freezes. If I use the dial to reset, it only goes to the next mile. I took the unit apart and cleaned and lubed all the innards, but no success. I'm thinking (but haven't taken it apart to verify) that one of the cogs on a gear is damaged. Not worth taking it apart if I can't repair it anyway. Is it possible to obtain/replace any of the gear mechanisms in the speedo? Other ideas?

<><><><><> <><><><><> Steve, The few odometers I've looked at had damage/wear to the greenish colored long and slim gear. One option to consider until you decide on a fix is to track fuel use and do maintenance based on the appropriate amount consumed.
