This is the same ignition used by top racers over the past 2 decades. The Dyna S is completely housed behind the ignition cover and uses a magnetic rotor with the original spark advancer, so the factory advance curve is maintained. Wires on the coils can be mounted on either terminal (no polarity + or -).
NOTE: This does NOT fit the "ND" (Nippondenso) type advancer. Take off the points cover and check the advancer, it should be stamped with "KD" (Kokusan Denso). If it's stamped"ND", you will need the DS3-2 ignition which we carry here.2 Magna High Output Coils. 4 NGK Spark Plug Caps.
