Need to valve the forks stiffer than shit (especially compared to stock).

The shock is more tricky - especially on the yamaha with the loose band - large bleed.

I'd add room for deflection to the comp stack, and personally I'd run a preloaded stack (done in a manner than preloads "low speed" portion).

Not sure if you do it all yourself or not - but if so pm me i'll send some suggestions.
