2004 Arctic Cat 500 has slow spark. Only sparks once for about 4 revolutions of the engine. Owner brought it to me after the other place couldn't fix it and had put in a New Stator and pickup, New Voltage Regulatort, New Ignition coil, New key Switch, New Left side handle bar control. I tested the Stator and pickup and both test with specks, Took side cover off and check to be sure maganets had not come ;loose and found this flywheel dosen't have seperate maganets. Connections seem tight and clean. Grounds are good, Spark is good and blue when it sparks, I tried a different Spark Plug for Grins and Giggles and no change. Is there anyway to test the CDI.
