The Yamaha and Honda both use 24 splines on the axle, for the hubs but they are slightly different diameter. I forget which is which but going one way fits tight (like Honda hubs on a Yamaha axle vs Yamaha hubs on Honda axle) the other fits loose. Sometimes either boring the hubs a little will let them work and sometimes they can be too loose and the axle will spin inside the hubs. Much will depend on the ware of each part.
