So when I got the bike the speedometer wasn't working. All the guage and instruments were good but it just read 0 mph at every speed. The day after the F1 code came up with the trouble light. Trouble code was 24 which is speed sensor. I haven't looked into it too hard but I just wanted to know what the likely culprit would be. Bad speed sensor at the sproket, cable pinched or cut, or maybe someone grinded off the tab to override the 189mph speed limiter? Should I follow the service manual procedure for checking the speed sensor, then trace the cable all the way up to the instrument panel? Where does the cable run through? Any help is greatly appreciated.
