I have a 2011 WR450f that I'm looking to put some parts on it off of a 2009 yz450f. I really have no need for the headlight or the taillight, or the battery/charging system to be honest.I'm really interested in having a yz450 top end with a wr bottom end. So with that being said, can I run a 2009 yz450f CDI box an harness? Also I would like to run a 2009 yz450f air box an sub frame, will that sub frame mount up to the 2011 wr450f frame? I have the GYTR competition kit, block off kit, 2009 yz450f IN/EX cams. That's all I have done to it so far.
