85 K100RS Speed Sensor
aka, Speedometer impulse Transmitter.
Is there a way to check this sensor?
I have replaced the broken gears within the speedometer unit and they seem turn everything freely.
I have tested and have good resistance from the wires that run from the sensor all the way to the speedo.
Now I am wondering if it the sensor,... the one that plugs into the rear hub and reads an impulse from the spinning impulse wheel when the rear wheel is turning is at fault.
I have checked A&S and BikeBandit and can not see this part listed for sale.
