cdi box question for a yz 450f

[bradb.]

I was just woundering if you can use a after market cdi box that came off a yfz 450 atv on the yz 450f mx. its got the same motor but I dont know if its the same set up.

If you know the brand of the CDI box, you can look up the maker on the intranet and see if the part# for both bike are the same or not.
