why do you hate the "feel" of the yfz?

well what a hate most is the seat its just not comfortable i think a YFZ motor in a 400ex frame would be the ultimate quad

you can interchange the old seats with the new ones which are improved. maybe there's kits available. oh, and when you take the YFZ motor out, may i have the rest?:devil:
