As part of this kit is included an uprated alternator from a Kawasaki. It allows 250 Watts instead of the original 150 Watts. Also included in the package is a modern regulator/rectifier and a modern pair of ignition coils.
The whole system replaces original equipment CDI or BTZ ignition systems with their abrupt jump from zero to 32º advance curve, which can cause jerky progress at the transition point, around 2500 to 3000rpm, especially in stop/go traffic. The new system completely eliminates this. Also, the ignition wiring is now approaching 40 years old and a common problem is crumbling insulation on ignition wires, as in the case of this bike.
It is currently a work in progress project but I thought you might appreciate some photos.
