I have a 2013 coolster 125 atv. It has all new wiring, the battery came out and shorted everything out. The magneto, starter, CDI, coil, handlebar switch, solenoid, harness, and battery are all new. It will fire right away, but if it stalls or you turn it off, it won't re-start due to lack of spark. I've eliminated the kill switch and still no spark.
