Resetting Guage Cluster

I was thinking that the rotating components of the average built-down-to-a-price motorcycle speedo are unlikely to have been dynamically balanced for high-RPM rotation nor equipped with a suitable bearing if they are designed to rotate slowly, and just the vibration of running continuously for 4 days and nights at 1000mph may cause things to self destruct, never mind the heat. I'm also thinking that if you run the speedo drive 8 times faster than it was ever designed to run, you are generating roughly 8 times the magnetic field and thus 8 times the current in the field coils and 8 times the turning moment on the pointer. Since the only thing stopping the pointer from spinning like a desk fan and winding the hair-spring up to destruction is usually a little end stop right down near the end of that long, thin, lightweight metal or plastic pointer, and the only thing stopping the central shaft spinning and leaving the pointer to drop off if that stop holds is usually a little detent or flat on the end of that tiny shaft, I wouldn't want to bet real money that the speedo would ever play the piano again after subjecting it to the 1000mph rewind experience.



The only way to know for sure would be for a MOron with time on his or her hands and a spare speedometer to rig something up and do an experiment for us, then write up the results.



In fact, that's just the kind of quality motorcuycle-related article I pay my subscription for. Get right on it, MO!

It seems that the sun melting the clocks thing isn't that rare, now I look... see http://www.google.co.uk/search?hl=en...G=Search&meta=
