Well put Kenaroo. I have a 2005 model and though it isn't raced, it's on the original valves without a hint of trouble since new. I just took it out for a post-ice storm spin on the neighborhood streets here in Louisville today. For doddling around town, it actually makes a nice ride. She's a little high-strung considering the offroad gearing, but it almost makes we want to make her "official" and get her plated. Actually feels as punchy as my old WR400 supermoto (again, probably the gearing).
