While riding my speedometer just stopped working and my odometer went blank. It continued to run until I got home. Then I turned off the bike. Turned it back to on/run and nothing. Won’t start. Any ideas?
Unfortunately the first place to start is to check for DTC/Error codes, however, if your speedometer is not working then you would need another device to check for codes? As you mentioned you have a Stage I upgrade by chance are you using a Tuner such as an FP3 or similar that can read error codes?
Without the ability to check for DTC codes I would start by checking the battery health, as well as the battery cables, end to end for tight connections and that there is no damage. You can also take a look at your fuse panel and check your fuses and relays 1 by 1 to include checking for corrosion at the contacts.
Near the starter, there is a ground cable which is close to the VSS sensor that sends signals to the Speedometer. Check to see that the sensor is not loose and the wires are not damaged. See photo with a white arrow pointing to the sensor.
