dont waist your time on the 250ex.  they wont get much faster then stock (driven by a drive shaft so you cant realy change the gearing ) also there isnt much mod's out there for a 250ex

best bet would be selling

well its cool that you want to get out there and build something, but its just not the right bike to do that sort of project. its just a slow bike, its intended to be a reliable beginners quad. 250ex is a good bike, i say enjoy it for what it is and eventually sell it and get what you want, a larger more powerful sport quad. and honestly, for the size and type of bike it is, i think they have plenty of power, i wouldnt expect a bike like that to need any more.
