I think with the 2001 in question - both the YZ and WR had a steel subframe.
The CDI also has a different ignition curve but with the YZ timing change, throttle stop and Grey wire mods it's not very noticeable when it comes to HP.
the WR has an 18" rear wheel, YZ has a 19", carb has some differences, primarily the ACV. Tank petcock has reserve setting.
