I have two 20mm generator/armatures in my spare parts box

This one came out of my 1968 r69us bike and assume it as a 75 watt because of the date of the bike
Generator
LJ/CGE60/6/1700R5
Armature
3104 013 403 larger wires on top of armature

This one I bought online as a pair and assume it is the 60 watt version
Generator
0101300004 G 7V 15A17
Armature
L140/3Z smaller more wires on top of armature

Does anyone else have a matched pair that was saved after a 12 volt upgrade and know what year the bike was and can forward the armature/generator numbers

Dam were is Vech and Richard
Happy retirement Vech

I had a similar problem,however mine was a simple case of turning the electronic voltage regulator adjuster screw clockwise which increase voltage output. Glad you figured it out!
