Okay I got a yz400f, now a few questions, mine is a yz and it had a dual sport kit which is currently in a box, but I will be reinstalling it. Anyway it came with many extra parts. It came with an extra airbox, the one that is in it has a green electrical box with a few wires hooked to it, I am assuming this is a WR airbox? Are the yz and the WR airboxes the same size? In other words will the yz airbox fit in the subframe if it is a wr subframe? Also it has a wr rear fender, will a yz bolt right up? I want to use a yz fender as I will be using a LED taillight.
