I just went to check out a 2001 KDX 220 to buy. It had all the goodies: FMF Gold Gnarly Torque Pipe and Silencer/Spark Arrestor, Carb work, Springs for the forks, all the little guards (skid plate, radiator, caliper, master cylinder, hand, etc), O-ring chain and 49 rear sprocket (don't know about the front), Handle Bars, Seat cover, etc. Questionable things: it lagged off the bottom end the first time I took it for a spin, then did ok the second time (maybe needed to be warmed up), and there was a noise in the top end that I noticed. I have no idea if it was bad, but I noticed it. It was a low pitch knocking, that sounded like it was coming from the piston. Also the spring on the clutch seemed really stiff. He is asking $2200, and I walked away because he wouldn't budge. Is it worth it? Do these sound like symptoms of any kind of potential problem? Should I go back and get it?
