Related question: My speedo ordinarily works fine (and I haven't tested with GPS, but common sense tells me it's roughly accurate). But sometimes when I ride at speed (60+) for an extended period, something will come loose and the needle will start bouncing around by +/- 10mph. Then later whatever it is will "seat" again and the jiggling will stop.Any idea what is coming loose?
One of our Ace enthusiasts from my site posted this link to some new Smiths style gauges with traditional vintage styles. I don't know how good they are, but it seems they might be worth a look.http://www.puca.co/speedos.html
