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 number in the comments section on checkout. 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.

Rectifier/Regulator Combination Unit
Bolt-on replacement for the stock regulator & rectifier (replaces both regulator and rectifier into one unit). Solves the problem of overcharging batteries. Simple to install - NO CUTTING OR SPLICING OF WIRES. Installation instructions: Remove the existing regulator & rectifier taking care with the bullet connectors. Bolt this new unit in the place of the old regulator (under the battery box). Plug the green connector into the electrical panel, connect the ground wire to the engine ground point (behind the kick starter), connect the wires normally going to the rectifier into the double female connector on this new unit and you are done. For troubleshooting questions, see our FAQ's. You will need slightly longer mounting bolts as the new unit is a little deeper.
