Fits Suzuki 1977-78 GS550- GS750 (with KD/KOK ignition).
Set and forget - no more messing with points... creates a stronger more consistent spark.

1977-78 GS550 & GS750 bikes --- some of these models came with a ND (Nippon Denso) ignition advancer. For these bikes a different Dyna-S ignition system is required. How do you tell? Take off the points cover- the ignition advancer should be stamped with "KD" (Kokusan Densi) or "ND" (Nippon Densi). If you have a ND unit- see the DYDS3-2 ignition system below.

Below are also the two different type points used for the KD & ND setups. Use these to determine if your bike has the KD or ND points installed.
1-year factory warranty.
