setting up suspension sag

hey guys, ive seen lots of different processes of setting up rear suspension sag, and fork sag. Was wondering what the numbers should be for the correct sag, and the process that you do to get it.
thanks.

Depends on what type of riding you're doing, but this is a good place to start.

Thanks for the link. Definitely helped. My rear shock was to soft. having trouble adjusting it as the collar probably hasn't been touched since 2007 haha. no matter how much leverage I get the tool won't break it loose And adjust. :O tryed all kinds of sprays too .

Isn't there a lock nut on there you have to loosen before you can make the adjustment? :O

Just use a chisel and hammer. I didn't have any luck trying a c spanner.

Yeah, be sure you loosen the top lock nut on it first. Then you can spin the bottom nut that's touching the spring. I can literally grab the spring and spin it on my dirt bike, but not so much on the Kawi, lol. You can use the wrench if you have it or a flathead/chisel with a rubber mallet if you don't.

lock nuts not coming loose either, thanks for the tips !

I used a flat blade screwdriver, and a hammer, to tap the locknut free on mine. Once that puppy was free of the lower nut, it was fairly easy to make the adjustment I wanted.
Anybody else around the 200 pound range not able to set front sag to 30mm with the stock springs? I maxed my preload. I had my son help and looking to confirm my numbers. I know the springs are soft but not that soft. Maybe the preload adjuster is not functioning? It does stop in both directions. I was able to set the rear to 30mm.

Front (top of seal):
L1 - 129mm
L2 - 93mm
L3 - 93mm

Edit: I probably should have included the process I used.

What are your thoughts on body position? I measured in a front straight tuck position, maybe I should sit just straight up?

The stock springs are most likely for a ~160 lbs. rider. You may need to get new springs for your current weight (fully geared up).
I definitely plan to get new springs but it won't be in time for the first track day so right now I am just trying to dial it in the best I can.

Someone mentioned the forks have a top-out spring so I am trying to find out if I am supposed to adjust for that. It is possible I cannot make a direct comparison from fully unloaded.


Edit: After enough research, I found that due to the top-out spring, I cannot adjust sag in the regular way using the preload adjuster. I will put it back to stock and make needed adjustments on the track. If that is what you were hinting at Strider, thanks.

Until you get new springs, at leat put a zip tie around your forks and make sure you aren't bottoming out. If you are bottoming out max the pre-load and increase the compression damping. Not ideal but the best you will be able to do with the stock springs.

Will do. I keep seeing the zip tie thing so it must be the right thing to do.
