i have a 07 250ex and im tryin to get some stuff that will boost up the power on it and some speed. ive already got a hmf full exhaust system coming soon but what else could i use to get more speed and power

 

start with a basic 3 stage mod. u got the pipe, now you need a jet kit and air filter. make sure to leave your filter box lid off once you got a filter on it, other then that im not sure, i never really worry about motor work.

 

alright thanks man

 

sell it and save for a 400ex or 450r
