I recently picked up a set of wheels from a 1990 Katana 600. Trying to figure out a way to throw the front wheel on first. I'll play with the rear later. From all the reading I had done, the Katana wheel was about as easy as it can be. However, I've barely started and I've already hit a snag... The DR axle won't fit through the centre hole of the Katana wheel's bearings. Does anyone know of an easy solution? Or am I looking at getting some custom bearings, or having to machine some bearings to fit? Surely there's an easier way. Any help is appreciated.
