Ignition Coil, DYNA Same as above, sold seperately. One coil fits either side. #  (Green) 3 Ohm.   $89.99 each
 

DYNA S Electronic Ignition 1973-80 Kawasaki Z1 KZ900  KZ1000 Replaces the stock contact breaker points, condenser and plate. No more replacing or adjusting points at every tune up. Just install and set the timing. This ignition system requires 3 ohm ignition coils. This system does not use or require an ignitor. Includes 1 year factory warranty. The DYNA S is a complete self-contained electronic ignition system built with the latest state-of-the-art engineering. 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. See a quick animated installation guide. See Electrical for more info/photos. Please include your engine serial # in the comments section. This insures you receive the right parts since the rotor is different from the early to late models in 1974 for Z1 models. Click here for rotor & advance unit photos.
