If it's running good in stock form, don't mess with it, The 250 makes usable power.
Any mods you make will require Re-jetting, and that's usually a 3 month ordeal till ya get it right.
Trust me, the HP gains are minimal compared to the hassle required..
My advice is spend your time getting the suspension set up for your weight & riding conditions- get the bike to stick before you get it to kick..
