i really wanted a kdx200, but have a chance to get a pretty good deal on a fresh kdx220. i ride almost exclusively woods trails. i do not add tons of aftermarket add-ons, or need a high revving mx type motor. what is the truth about the kdx220 stock piston being prone to failure?? the bike i am looking at is a factory piston, 2001 220. i really need input on this one from ACTUAL kdx 220 owners. i would like to hear the horror stories and the good reports. thanks alot!!
