I have a 1993 Vfr 750 fn. Just destroyed my new top bearing trying to fit it! I bought a kit from wemoto and the bottom bearing fits perfect but after much heating and building a rig to fit the top one it finally gave way and has stripped the lower threads from the head stock. I am looking for the inner diameter of the top bearing if anyone knows or a new headstock if anyone has one knocking about in the shed. Other than that a little advice about where to get one or how to fit a bearing that is too small.
