Have a dead speedo/odometer/trip meter on my 1993 K1100LT. Have looked through all the suggested lists and tech sites for solutions, with no success. So in the end have taken it to a company specialising in repairing guages and meters, where they have bench tested it, to find it is faulty. Got a quote for $250 to fix just the speedo or $350 to fix the the odometer, trip meter as well.
So am getting both fixed. Have looked online for second hand one's and works out at least the same cost, plus postage to Australia. Brand new one's are dearer, or in MPH which isn't much good out here as we use KPH speed limits. I don't know exactly whats wrong with, but will try to find out when I pick it up and will post anything I find out on here for others that may have the same problem speedo.

interesting issue bob

yeah would like to hear of the outcome

my fist suspicion is that the gear on the odo have split ...lost teeth

but I wouldn't hold that as the reason for the failure of the speedo

often found to be In the film circuit board ...and or connections to the motor assembly

also the input to instruments connections

just out of interest I was looking at some instrument diagrams today (for some investigation into tacho issues actually ) but remembered this






you will notice the film circuit board connected to pins that then go to the electronics of the mechanism ...some times the circuit connection become open circuit ...often repaired by installing a bit of wire from the input to the meters connection points

the motor assembly drives off the film connector towards the top of the picture ... and could also have intermittent connections
