I've been looking into it for a while now. I have lived in Texas most of my life and never have made it out to Big Bend. I always seem to be headed somewhere past it and end up passing it by all the time. (it's so far from anything else) But I've been riding with the TWTex guys for some time now and feel it's a must now. I need to get things lined up to do it but hopefully I can pull it off. Will probably bring the TW as well as my XR. What gearing and jetting did you use last year with your TW? Was it correct for the riding you did? How much pavement did you run??? How cold did it get while riding and at night?
