I have an '86 GL1200 Asp. with a bad speed sensor. Neither the speedometer or the self canceling turn signals work. Does anyone out there know if these are repairable? I had a used one from an '84 that I am redoing, but found that there are three different part numbers throughout the four years of the 1200s. The sensor from the '84 works fine but the speed reading is not correct (reads faster than actual speed). Naturally these are no longer available through Honda. If anyone out there has a good sensor from an '85 or '86, I'd be interested.
