Ive heard somewhere that adding things pipes and air filters and rejetting just makes it get to the top end faster and to make it go faster than that you need to get a rev limiter? is this true and how much are these and are they easy to install on a 250ex

 

the 250ex isnt worth that kind of money IMO wait until u get a real quad to start doing those types of mods. not saying the 250ex is a bad quad but you wont notice any considerable increase in speed for the amount u will spend. save your money and get a 300 or 400ex, something along those lines then start spending money on mods.

 

so how much is a rev limiter anyways
