Why are there holes in the float bowl on a kz750b?
In the picture showing the rebuild parts for a KZ750B note the odd float bowl gasket with all the holes in the middle. This is to accomodate the passages for the main and pilot jets inside the float bowl. The pilot mixture screw does not use an oring.
