    As far as know the only extra parts you'll have to buy are a pair of 25 spline wheel hubs. The 400's are 24 and the 250r's are 25. I'm doing the same thing so hopefully someone can confirm that is all that's needed.

    you also have to have the 250r axle nut. the 400ex one isn't wide enough to tighten it down on the snap ring.
