48mm forks came out on the 2002 model.

The Flyin Hawaiian:
I believe the 48s came out on the 03s when kawasaki redid the bike.

I have a book that discusses the flaws with all the different models of race bikes in Kawasaki, honda, suzuki, and yamaha.  The 1997-2000 Kawi's all have the same basic problems: "power hits hard, sticky shifting, soft forks".  The fix: "Porting, updated detent spring, stiffer fork springs".  2001-2004: flaws:"midrange only powerband"  fix: "porting for more exhaust timing, Pro-Circuit pipe and silencer"

Don't know if it will help but I would go with the one that needs less work and the lowest hours.

Hillclimbers have great low hour bikes, which are set-up perfectly. Alot of times they want to change classes or have many bikes. Most bikes are rebuilt three times a year with less than an hour of ride time. All of this plus usually very clean inside and out.

good advice...  Hope i can help...

The 98 KX 250 had a monster motor, The updated detent was actually a step backward, the fix was to use the previous years shift detent. Suspension is rider sensitive, so if your lighter you may be OK otherwise you may need heavier springs. The 06 has a killer mid range and up powerband, with very little bottom end, I don't like it but my son does. The best motor mod for the 97-02 250 is the Wiesco flat top piston mod, it totally enhances the power band, Tom Morgan did my head and it ripped. I think the 05 and newer would be my first choice, they have the twin chamber KYB's, and they work well.
