I want to know how much and if its a good idea to put a wide ratio tranny(well, you know the tranny gears) in a mx bike like a Kx 250.. I like the KDX and its 6 speed but not enough for me and i like the punch of my friends KX and wonder if i put a wide ratio in there,,, would i be satisfied??? I know that ill have to give up a little of both worlds but let me know if u have done this and the result!!! any help would be nice ,,,Thanx!!! -Speedy
