        JBM Industries does, they make Yamaha XS650 BS34 replacement diaphragms that I believe are the exact same as the BS32's aside from the larger slide they are glued to. Google them. The guy is a vintage aviation enthusiast that also got into making repros of a few obsolete motorcycle parts for his friends/acquaintances, so he doesnt have much in the way of motorcycle specific knowledge, but it seems his parts are great quality.

          SUDCO has the diaphragms and any other part you might need also.

            You have to buy the diaphragm AND the $$$slide$$$ from anywhere but JBM, who sells just the diaphragm for you to glue to your slide as the OEM units are attached. $20-something vs $100 each sounds GREAT.

                You could also try these diaphragms, then you don't have to cut the plastic rings on the slide

                  Greetings,
                  Is there a forum member who, as a vendor, refurbishes these GS carbs? In my case the Mikuni VM26SS.
                  Regards,
                  JZ.

                    There have been in the past, but I'm not sure if anyone is currently advertising a carburetor rebuild service. I would do it for you if I were caught up, but at this point, I'm at like a year behind on everything! Mostly friends bikes and my projects... and a full house rehab that is waiting for me, but it can sit there. Add another few months to that backlog!

                        Is this the place where I can ask a question? I am new to the Forum and can't figure out where to go/post. My questions concern a 1982 Suzuki GS650G that used to run very well a few years back. Thank you in advance... zanichbug

                          As of 07/22/2023 the link for learning about carb functions is broken

                            Got the GS650 mostly running. Turns over perfectly when I depress the starter button, but dies when I release the button. Electrical issue, or vacuum/carb type problem. Thank you...
