I did an oil change then after about 2 miles i reset the trip meter and now the speedometer is pegged at zero. Did it just crap out or is there something funny about these older honda speedos that I should know?
You can tell very easily if the issue is the speedometer itself or the cable. Unscrew the cable from the back of the speedometer and see if the inner cable spins when you roll the bike forward. If the cable still spins, then the speedometer is the issue, if the cable doesn’t spin then it is broken and needs replacing. Old cables break regularly. It’s an easy fix.
