The ignition systems I have checked on CDI motorcycles have a 20v ac or so voltage at about 200 rpm to around 60+vac running then is stepped up in the CDI module somehow then discharged into a low ohms coil usually .5-1 ohm on the primary and about 5-6k on the secondary with usually 15-25+k volts at the spark plug.I'm thinking I have read or heard of cascading or paralleling capacitors in some fashion in the final stage of the CDI unit to multiply the source voltage to the primary of the high tension coil.This is a 2 cyl engine but want to treat it like two singles. Thanks, Rick
