After 5 years I think he got it fixed by now
A simple TIG weld up of the journal and remachining of the bore works . For a mild worn journal a person can just face .005-.01" of the top face of the head (or cover , which ever side is worn worse ) and rebore the journals with no welding.
I'd be very Leary of those bushings sliding sideways or spinning and jamming with no locking notches like main crank bearings in auto motors.
Kawasaki also casts a little pocket in the middle of the bottom journals to hold oil for start-up till oil is fully circulating. A person can drill a few small dimples in the Yamaha journal that doesn't have any to do the same to help out.
