Simmo
I have a 2000 ZX6R, I dont know the difference between the ZX600R and ZX6R but here in Australia there is almost no difference between the 2000 ZX6R and the 2001 ZX6R.
So here are the standard settings for the ZX6R as described in my owners manual, I hope they help:
Front forks:
Spring Preload 14mm (0.6") from top of adjuster
Rebound Damping Force Adjuster 7th click from fully turned in position
Compression Damping Force Adjuster 9th click from fully turned in position
* Spring preloadadjuster requires a wrench (spanner) for adjustment, turn the 'blue' nut for adjustment from 5mm - 20mm measured from top of blue nut to the lower nut on the triple clamp
* Rebound can be adjusted using a screw driver to move the 'screw' type looking adjuster on top of the front fork
* Compression can be adjusted with a screw driver, the adjuster is located at the bottom trailing edge of the front forks (it looks the same as the rebound adjuster)
Rear Suspension:
Rebound Damping Force 10th click from fully turned in position
Compression Dampin Force 10th click form fully turned in position
Spring Preload - my ZX6R owners manual says for adjustment "have it adjusted by your Kawasaki authorized dealer" It can be adjusted but I have not adjusted mine and I am unsure of how to do it. It can be that hard. Check out
www.kawiforums.com post your question there, one of the members there might be able to help.
* Rebound adjuster can be found right below the rear suspension spring
* Compression adjuster can be found at the top of the spring on the bottom of the reservoir
Both use a screw driver for adjustment just like the front forks.
Good Luck
