Opened up my forks because they where stiff and non-compliant and,

Oil was dirty

One cartridge had air

One cartridge has leaking seal

The shims are different than what I have seen in the stack index.

I'm going to do springs for my weight 215.

I would like to know whatup with these stacks, please comment.

So there are extra shims on the reb and comp side of the mid valve but the float also increased to .40,

How can this be achieved ?

Ics are not normally preloaded , if the collar is a different length or shims under it , you can increase the float with a stiffer stack

Where did you get that shim chart ?

The stack listed for the mid (not the one in the chart) reminds me of the mid from the newer style mid that KYB used for a couple of years.

I found the chart here on TT. The link for 2009 in the valve index is bad. There was a Procircuit KYB works kit sticker on the the forks when I bought it, but I thought it was just s sticker. I ve looked for a stamp on the springs and forkleg but not found anything. Looking at a DIY kit from Dave J, but I wanna get what I have figured out, working properly, and new springs first. What type of riding would these stacks be geared towards?

Thanks for the help!

Looking up info on drilling my free piston and noticed that mine has no bushings. Is this the factory part or a replacement ?

rebound piston holder is from an 11-12, can anyone comment on why these would be changed out or an upgrade?

This is the piston holder that should have been in these forks.

This is the one I have

Would this piston holder act as a lowering spacer for the cartridge?

Looks that way , are the springs shorter or have been repositioned ?

The springs appear to be 1/2 in under what is in the manual, 18 7/16 instead of 18.9in.

The difference on the post looks to be 16-17mm.

Can I buy aftermarket spring seats and mill off the top, or use the shorter showas seats and add preload spacers ?

Already purchased new springs and lowering the bike a little wouldn't hurt my feelings.
