    bad disphragm repair or replace?

    so my 81 gs750e was running alittle rough and im tearing appart the carbs and i noticed the diaphragm on carb #2 has a small hole in it... so should i try the "Plasti Dip" spray-on heavy duty flexible rubber coating or try and get a new diaphragm? will one off a 87 gs450 work, they appear to have the same carbs just jetted diffrently.

          New diaphragms are killer expensive. I'd post in the Parts Wanted forum for one used BS32 diaphragm. Much cheaper than buying a complete set of carbs.

              If it was me Id at least TRY your fix.

              For all we know it might hold up remarkably well and save many GS owners the ridiculous cost of replacement.

                          I would use the liquid "Plasti Dip dab some on the hole with a tooth pick

                                      You can fix it, but I wouldn't ride across country on it just yet...

                                      Personally I'd buy a new one, just to eliminate the possibility of more problems when your riding down the highway on only 2 wheels.
