Here is a quick list of the improvements made to the 99 that I can think of:

1) Excel rims
2) Thinner and larger rear brake rotor 240mm from 220mm
3) Rear hub has less weight
4) Slightly lighter swing arm
5) More durable kick-starter
6) Improved water pump impeller shaft and seal configuration
7) Bosses in right case removed (for auto decompression assy or electric start – does anybody really know what this was going to be used for?)
8) Valve springs slightly longer with slightly a reduced k coefficient
9) Carb has reworked low speed passages for improved starting and throttle response
10) Hot start knob is a little shorter and red
11) Foot peg mounts relocated
12) Shock/fork valving changed and other internal tweaks
