I have a 2002 sportsman 500 6x6. Ive managed to fix most of the problems but after rebuilding the carb and running the engine it wouldnt shut off with the key or the handlebar mounted kill switch. Both the switch and the key work to turn off everything else, and had worked to kill the engine before i worked on the carb. Also now the speedometer jumps all over when the ignition is on without the bike moving? Can anyone help me figure out whats wrong with this thing, preferably with info on how to fix the problem?
