Hello so I have a 1979 XS400 I made into a hard tail bobber. I cracked the lower engine case and can't fix it. I was going to get a new lower and upper case but Yamaha doesn't sell crankshaft plane bearings anymore so I'm thinking about swapping for a bigger motor. Is there anyone out there whose swapped motors with minor or no fab work to the frame? Thanks!:bike:
 
I would try to find a donor motor to swap or one with a good lower end. There are no motors that will drop it without doing mods to the bike. Try speed and sport (yamatopdog.com) for bearings or google the part numbers and see what comes up. A lot of the time the standard bearings are all you need and of five motors that I have pulled apart, all still had good originals in them.
