ok, what all dose it take to put a wr bottom end on an 03 yz450f? it needs a rebuild anyway so i figured id attemp to put a wr bottom for the stator. just dont know if i can bolt it on and be fine or if it takes slight modification. and im not asking to be told to go buy a wr. i want to build this one. just dont know what i need.

You can bolt the '03-'06 WR crankcase assembly directly into the frame.

the only thing i can think that may be different is the wiring harness due to the added electrical components of a wr, but i am no wr expert
