I have an '03 400 and love it. Just over 200 hrs and still going strong. Planning a motor re-build this winter (hope it makes it through this season). Makes an excellent woods weapon. The motor makes great power (mid 40's I believe) and its fairly light with top notch suspension. My upgrades have been a suspension re-build, FCR carb, and a steering damper. It's a very capable machine and way better at this stuff than me :roll:
