as long as it's in the right year range, yes.
Frames are the same between the small and big bikes, YZ and WR for the appropriate years. For instance a 1998-2002 frame and any engine from those years will bolt right up. 03 to 05 engines might bot right up too....I don't think the main frame changed until 06...
