I have an XT225 motor with the regulator, cdi box , coil and battery hooked up. The only thing not hooked up are the blue/yellow wire and black/white wire out of the cdi. I can turn the motor over by tapping the starter wire to the battery. Should it run like this or are these 2 wires out of the CDI looking for something? If so..what? It sparks 2 or 3 times on the spark plug(tries to start) but then the spark goes away. Please help!!!
