I really want to get away from points and want a CDI with a true advance curve. I dug up a complete KX85 Ignition system and decided it can be made to fit my V1 engine. I decided the KX ignition could be adapted for various reasons including:
The height of the stator is very close between the two ignitions.
The KX flywheel is smaller and with the ignition trigger coil outside, extra room helps.
The KX stator is easy to add a 40 watt 12 volt coil to.
The KX flywheel has a riveted hub that can be replaced.
