Just in case anyone was interested, I did find those old articles on Baghira mods from the now-defunct U.S. MZ distributor website (thanks andyw!).
Given the collective wisdom of this group (as cataloged in the archives of this very website), these write-ups might seem somewhat simple and boring, but some may find them helpful, if for no other reason than to provide confirmation of an already-known issue/source/technique/etc.
At the very least, I can confirm that the good words written about Bernd Lischo and Competitive Solutions in these pages are accurate. I'm currently installing the CS powerheader, connector tube, and carb kit on my Baggy. Bernd has been incredibly helpful, and the quality of the parts is first rate.
There were only four articles that I remember. If anyone has any others they recall, I can look them up in the archive and post them here as well.
