josh,
as with most type of offroad toys your want to chane the suspension as one of your first steps. then pipes. then look into an adjustable timing plate. VF3 reeds. Coolhead. Dyna ignition. Stroker crank, carbs ,pistons, new clutch with a lockup, override. the list ogs on and on. these arnt in order persay but they are a pretty good to get you going in th right direction... the list is endless.
