Hello all, first time posting. I have recently acquired a ‘75 CB125s. 6 volt. I’m planning on “upgrading” the electrical system with a M-Unit blue. I have a new battery on the way and would like to get started this weekend. Is there a good example of the proper wiring for the m-unit and Cb125s? Plenty for 550’s, 750’s, etc. but nothing I can find for the 125. I have wire, connectors, and all the tools I need. Also, any tips or must do’s/dont’s when going about this install would be amazing. Thanks in advance!

The main difference between your bike and any of the other models you mentioned would be the charging circuit. Everything else will be more-or-less the same.

If you need help with something specific, please let us know.
