On the opposite note:

The other way from 3/4 to 5/8 shaft reducer is something I was looking to find at one time. Unfortunately it is not just that the shaft is lengthened in the process, but I found the cost of the item varies between 100 to 400 dollars. If anyone sees shaft reducers that are less cost, then rather than buying another clutch I might use one of these. It is also pertinent to know if the belt or chain is going to fit in the new location further from the crankcase wall.
