I'm a newbie and i've been on the board for the last few weeks reading alot and decided to get my 13 yr. old a mint 2002 KDX220 with just a couple of hrs. on it. Great price! The guy traded it at the local dealer for a KX-250! Plan to check with the previous owner and see how it was broken in. Just reading about some of the piston problems with the 220 on the message board. I figure everything should be o.k. till time for a set of rings. Plan to replace the top end at that time with a Wiseco kit and maybe a pipe if he keeps his grades up! Looking forward to some "Good Times" with the KDX!
