:coollep:The Guru's will be along soon, but Have to ask
1. Has it been acting up-such as the needle jumping instead of running smoothly ?
2. Has the speedo cable come loose (this happen on my 82 Asspy)
There are a number of possibilities as I said the Guru's will be along shortly
this also would be my 2 cents worth.The speedometer and odometer run off the same sensor so that tells us the speed sensor on the front wheel is working. Troubleshooting in the manual does not deal with this situation but an educated guess is the speedometer LCD unit is bad or there is a problem in the circuit board. May times I have been able to repair circuit boards by examining them closely for cracked solder joints and remelting the solder on cracked ones. My eyes don't allow much of this anymore unfortunately.
