Does anyone know if 05 wr450 bottom end cases are compatable with a yz450f? Instead of getting mine welded I would like to find a used set. Really only need the left side.

No, they aren't. You'd need the crank and the complete generator assembly, along with the left side cover, to make that work. Only an '03-'05 YZ450 case will fit yours.

BTW, crankcases are bored while bolted together to guaranty that all the shafts line up. They are sold only in pairs, and should NEVER be used separately with another case they weren't originally line bored with.
