Look on ebay for a an engine or rebuild what you have.
The yz may not be a good idea unless you put in the wire harness and CDI box. No elect. start with the yz.

If you change motors, you have to change harnesses too.
If you look on ebay for WR parts, you will find the same few salvage yards selling.
Call them up and have them look for a WR motor.
