The turn signal relay counts pulses from the wheel speed sensor, and shuts off after a predetermined number is reached. The faster you are going, the quicker it shuts off. If you are not moving, there are no pulses to count, so the flasher stays on. On K bikes from 1985 to 2001, the signal came from the speedometer impulse pickup on the final drive. On 2002 and later bikes with integral brakes, the abs system shares the wheel speed impulses with the speedometer and the turn signal relay. The radio also uses the signal to increase the volume as you go faster. As far as I know, the flasher relay can not be reprogrammed to count fewer or more pulses before it shuts off.
