| Like all JBM Industries replacement diaphragms, a thick center tire section is used to replace both plastic rings. The hole in the tire is slightly smaller than the carburetor slide groove, so there is tension from the rubber holding the slide. These diaphragms must be positioned by the installer so that slide and air hole faces in the proper direction. Sheng Wey 60 mm OD diaphragm from a Johnny Pag Motorcycle shown. |
