Does anyone no if the left side rad from a 99 Yz 400f will fit a 2001 426.

Not without a '99 radiator shroud. The angle of the flange that attaches the shroud to the radiator is different. You could try to "tweak" the radiator, but bending it that far risks busting a seam...

Isn't the YZ radiator smaller than the WR radiator?

It might be...they do have different part numbers on the '99 models. On the '01 426's, both the YZ and WR share the same part numbers. The 250's are different, though, too.
