CDI Ignition Box

My dad bought me a wr 450 because it was a green sticker. I realize that some of the componets on the wr and the yzf arent the same, but i was wondering if i bought a yzf Pro Circuit CDI Ignition Box, would it work on my wr? i already got rid of the smog stuff and all that if that helps any.

wr 03-06 all same cdi

yz 03-05-06 are all different

the book says no but thats all i can say

I agree, the WR is totally different from the YZ. The Wr450 has a 12V-DC-CDI, and the YZ is magneto.
