    Miscellaneous Discussion
    Hey All, I have a 1972 CB350 that I'm reviving. So far it's been a fairly straight forward project but I've been struggling to resolve this issue.

  6. 69 CB350 front brake cable sensor

    Electrical Issues
    I’m looking for advice on what to do with my 69 CB350 front brake cable. I can’t find an OE cable that has the electrical sensor inline. All the replacements don’t have said inline sensor. What do I do? I really don’t like the idea of the front brake not illuminating the rear brake light when...
