Has anyone had problems with the ignition pickup coil failing or gotten weak. I have tried 2 different aftermarket cdi controllers and both of them misfire. The stock one runs fine. I tested the resistance of the sensor, test 114 0hms in spec. now the cranking voltage is way off. Kawy says should be 2v or greater, mine read max 310mv. Now i searched the forurms, and no one has replaced one. But i have read similar post, but no one have replaced one? It is funny it will run with the stock cdi but not the performance ones. I don't mind changing it as long as it works, and not find out the rotor is weak and lost its magnetism.
