97 Sportster speedo and self canceling signals quit working I have taken the speed sensor out and cleaned it but still does not work could the sensor still be bad or could it be the the turn module?

Yes, the speed sensor could still be faulty even after cleaning it, so it's worth testing or replacing it. Additionally, the turn signal module could be the culprit if the signals are not self-canceling. If both components seem fine, check the wiring and connections for any damage. Testing the system with a multimeter can help isolate the issue further.
