I don't think he said anything about sand?? Anyway, I would put a torqe pipe on there, change the gearing and possibly add a vforce 2 on there (set for torque). Good tires for whatever the conditions works wanders. Make sure you change the springs for your weight and a revalve would be good. Barkbusters are good (definetly worth the money). I've heard a oversized front rotor would add to your breaking power and feel... I think they have an oversized kit for the rear also, but this would be expensive.
I think if you do a search you find a lot of good info on the subject! Do the research first and you might answer your own questions and save some bandwidth.
