my speedometer stop working on 1999 k1200lt it jumps now.Does anyone know what could be wrong with it? It did this before but it started working but now it just jumps going from o-40 mph. other times it does nothing .I checked were the brake line changes from metal to rubber but every thing is ok there so I bought another speed o cable and replaced the one that was on the bike but it still does not work. One member wrote was there any other symptoms but everything works fine radio vol. control and cruise control is ok.
