I ride 40% of the time on one wheel and even the 01 took all of it. Not bad for a "first year" model. And more times than not back in the day It would slam down so hard I thought I was going to bend the rim. That was back in the learning process and it has smoothed out a lot now but I still am rough on th bike. I would never think there was a frame issus with these bikes. Now Your valve guides could be that way from any number of things... like sitting stagnet all winter and in the condensation some rust formed or maybe an oil that didnt agree with them or maybe you had a valve tighten up and burn one to the point of scaring it a little. who knows. And a much easier fix than buying a new bike. Don't be scared to rip into that bad boy. When i Turboed out my 01 it needed a new head spacer gasket and I had to re-degree the cams with the adjustable cam sprocket I put on it. Not all that bad. Nice little Sat. afternoon project for a man of average skills and limited tools.
