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
