from what ive seen, and dont hate by this, by Mike White, is that the bars should be a couple inches longer than half the width of the frame. that allows for more suspension travel.
heres a good pic off of his website
also, i've never really worked with one before, but ive done a bit of reading on them, and that is how i would set one up. also, be sure that the bars are parallel to the ground at ride height.
