Very nice site you have here!
I'm a kawaholic from washington state and own a 94 kx500 and a 02 kx250. The 5 does dirt and pavement duties, have a set of 17's laced up with a monster front disc for supermoto and some other stuff. Currently the motor is getting some love after the antifreeze drain bolt backed out 40 miles into a woods ride, should run hard when it's done:x
The 250 is pretty much stock other than tapers, great bike!
I'll probably be around for a bit, looks like some real good info on the kx's here!
