    81 GS450 Carburetor air mixture screw

    Anyone know of an aftermarket option for my 81 suzuki gs450??
    I lost a pilot air mixture screw and it is impossible to find a replacement screw for it and now im stuck looking for a new carb. Right now ebay has a few for $180 - $300 so I'd like to explore aftermarket parts....

    Any suggestions or experience with this?

    Can you post up a high quality photo of the screw? Include some dimensions, using a pair of calipers. Maybe the screws cross reference against some other model bike carbs?

      Some of ya'll know, but I don't, the parts places, that if you put in the oem. pt # it will show other bikes that part was used in.

        All true, except, Suzuki never sold pilot screws separate, as a service part, so there is no path forward that way.

          Aw shoot, might have known. Guess they thought nobody would ever need one, kind'f like the tops for all those GS1000 and GS1100 air boxes.
