I bought an `00 426 early this year. Got it from a trustworthy dealer with just one owner, unraced and in excellent condition. You could say it looked brand new when I got it. I've ran about 5 tanks through it mostly trail riding. A few times on the track but not to race, some hill climbs. I havn't beat on the bike but I have ran it hard. Every once in the while there's a post about the "problem prone" 2000 YZ426F. I've had none whatsoever. But, I'd like to know what these alledged problems are so maybe I can correct them before they really become a problem. Anyone wishing to give me some feedback on this would be doing a me a great favor....of course this looks good on your karma sheet too!
