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!
