You could have a bad cdi box but more likely with this model , you have bad pulsar pick ups, which unfortunately are part of the alternator assembly. These can be checked without removing the engine by taking readings from the plug going to the cdi box. ac generator disconnect the stator wires at their connections. X10omega
