After weeks of painful consideration of various 400-class dirtbikes, I bit-the-bullet last night and bought a 2001 400EXC. I'm a 34-year-old rider with 20+ years of experience riding hare scrambles, trail riding, and very little motocross. I'm a little nervous, because I'm a 2-stroke rider, and the idea of going back to a 4-stroke (my last one was an XR200 in 1982), seems a little scary, but I'm looking forward to my first dual sport ride in September. Any advice you can give me about setup, or starting problems, or etc.?
