I have an 07 outlander 500 and last night I was riding it and my speedometer started jumping around going from 30 mph to 10 mph etc... and I thought that maybe if I switched it to digital readout that the problem might be in my analog gauge. It did the same thing on the digital readout but my tachometer worked fine on both the digital and the analog making me thinks that my gauge cluster is fine. Any suggestions on what it might be if its a sensor or something causing this?
