i have a 2005 yfz with sparks exhaust, air filter, jets, and cam timing mod. i need a higher reving rev box but i don't know what kind to get. i don't know if i should get a adjustable one or a straight one. i have heard good things about gytr ones but im still not sure. i drag 300ft so i need one that works the best for that.
