Michael, I do have the bracket you took a photo of, and I currently have the main chain guard fitted. It just seemed odd that the clutch sprocket area did not have anything covering it on my bike. The leading edge of the primary chain being exposed to the elements just does not seem right to me. Daren, that drawing looks like what I was hoping to find, now whether or not that is appropriate for the B29 remains to be seen.
I really appreciate all the help with this!
