OK, I just went to look at a 2002 YZ426F. I drove 2.5 hours to look at it and it looked really good, so I made a deal with this guy, loaded it up, paid him, got the title and started home. About an hour back towards home, I looked at the title a little closer, and DOH - it's a 2000!!!! I felt pretty stupid - I had gone over that bike with a fine tooth comb. I even found a bolt missing out of the shroud and made him knock another $25 off the bike. I had even checked the VIN on the bike to make sure it matched the title, but damned if I didn't check the year! I called the guy to talk to him about it, and I truly believe that he thought it was a 2002 - he seemed pretty pissed at the guy he bought it from. He offered to pay me the difference between the 2 years according to NADA (which turned out to be $35 - whoopie!), but I feel I got a good enough deal on it that it isn't really an issue. What I am worried about is, it seems like I have read about a few problems with the early 2000's that were taken care of later in production - am I right? What do I have to worry about? Did I really get screwed on this deal, or am I OK?
