For better starting properties of the Yamaha and on explicitly customers' request we have changed the rotor (now: 1.4 kg/ 112mm diameter / 180W - previously: 0.7kg / 103mm diameter / 100W).
Magnet based generator with integrated solid state ignition. Replaces all original generator and ignition parts. Updates your system to 12V/180W DC. There is no need for changes on engine casing.
