Would like to know if I can put a YZ 450 crank assembly in my 03 WR450???
Is there a difference because of the starter clutch assembly?:thumbsup:

There is indeed. The left side crank axle of the YZ crank is shorter, so your flywheel/starter drive won't fit.

Part numbers don't tell the whole story, though. There are several parts that are more or less totally interchangeable but have completely different numbers. Yours was a reasonable question.
