When mounting a CR500R motor in a CRF 450 Frame, the rear engine mount that the swingarm pivot shaft goes through is more narrow than the CRF engine mount. This leaves the shaft and to some extent, the bearings exposed. I had some brass bushings cut to cover the exposed areas. Attached are pictures and a drawing with the dimensions of the bushings.
