This is a replacement throttle slide diaphragm for the Mikuni BDS carburetors as used on the Yamaha XVZ1300.
Please note that replacing this diaphragm does require a certain degree of handicraft.
This diaphragm is supplied complete with the glue and tie-strap that are required for the assembly.
Normally this diaphragm is not available as a separate spare part but as the existing stocks of complete throttle slides are getting depleted, this is an excellent alternative to such a complete slide.
This is a Carburetor City diaphragm, precision-moulded for us in Germany to an exceedingly high standard.
