      I have a 2013 gv125 the Speedo works fine but the rev counter and the small round digital display telling my how much fuel I have left and how many miles the bike has done aren’t working any ideas on where to start looking? Thank in advance

      Follow wires from it back as far as you can look for broken or damaged wires, check the connections all connected no corrosion.  look for any changes in the display as you move wire

      It sounds like a bad wire somewhere finding it is the hard part

      What he said and make sure to follow the RED wire , it is what actually activates the LCD middle display , and  rev counter = check coils , stator and the yellow/black wire (usually) for the dash unit to read RPM signals coming from the aformentioned parts i just mentioned.
