Invest in a shorter swing arm, different tires, mill your head or replace it with a noss head, and invest in some suspension. After that you'll probably want to have an mx port done to it, invest in some after market reed cages or have yours redone, advance the timing, and lighten up your flywheel. The list goes on and on. I'm not a huge trail rider so I am sure others will let you know which ones to due first. That would make it kick ass not that you need to all that stuff to have fun in the woods...
