When you say not the switch, are you referring to the stop light switch? I have seen ones that look good (ie my 750) and actually were bad. Also, you may be able to adjust the brake pedal (lock nut on threaded brake pedal rod) to keep the pedal arm from the stop light switch. I had to do that on my 750 after repalcing the switch, the pedal arm was keeping the projection on the switch from fully disengaging. Hoep this helps and you can understand my colonial english.
