The ones that i remember at this time:
Eric Gorr bore & porting (KDX225), RB-Designs Carb mod, 607 Boyseen Power Reeds, Open Air Box, Graphics kit & seat cover, KX Rear Fender, Aluminum Bars (Renthal CR HI), Freddette Lever Guards, IMS Pro Series Foot Pegs, FMF Gnarly Pipes (KG-35 and KG-30), FMF Turbine Core II S/SA, MSR Shift Lever, fredette chain guide, X-ring chain (D.I.D.), 13/50 gearing, XR250 Clutch Friction Plates, stiffer clutch springs, MX Tech Shock & Fork (.42). I'm sure there's more.
THe KDX200 +25 has been a great bike for me and i love to ride it (way more than my buddies KDX220).
My KDX has now turned into a spare bike for friends to ride as i bought a 2006 CRF250X this summer. Simply love the Honda but can't imagine getting rid of the KDX.
