I plan on going to silver lake at the end of the month. I have a mostly stock 400ex and my riding buddy has a raptor with a yoshi pipe. I live in PA so i do not know anything about riding on sand. What kind of setup should I run? I have almost worn out front stock tires and half worn razr's on the back. Should I get new front tires before I go? I am waiting for the razor 2 tires to come out. I don't really want to buy sand tires for one ride. Around here the 400 and the raptor run equal but from what I hear I will get killed on sand. Eating sand roost all day does not sound that fun, is there anything that could help me out? Does anyone have some tips on riding on the dunes or where we should camp?
