Mid-valves?
Note: Most 1995 thru 1997 use a "mid valve" located on the rebound piston (located on the pushrod assembly, fig 8). This works for supercross and some very aggressive pro riders but is too harsh for outdoor use. Race Tech recommends converting the "mid valve" back to the standard check plate design (just like the compression assembly). Remove the existing "mid valve" parts and reinstall the cupped washer, sleeve, check spring, check valve plate, rebound piston (recess towards check plate), rebound valving, base plate, and nut.

You know, some would argue that removing the midvalve would be a step backwards in technology.

I just don't think it is perfected yet.

I think it is just a lot harder to teach someone to tune a midvalve than it is to replace it with the RT check valve.
By the way, I think midvalves are 1995 and on, so that means it has already been on the market for 10.5 years.

He did talk about the midvalve but didn't really say if it was replaced with a different design, reworked or replaced with a check plate. Anyone else find anything on this? I would like to get an idea on how to utilize the midvalve if at all possible.

Reading deeper... I guess they used a cylinder valve replacement kit. Question is... who is it made by?

I think the device mentioned is not for every single fork with a midvalve. I want to say that the YZ forks for a couple of years had some specific setup problem. I don't want to pour through all the various suspension forum threads, but you can. :-)
Good luck on the surgery.

Well... the question would be... How do I utilize the midvalve in a 03 KX forks to eliminate the harshness? Gold Valves and....??????
Of course I haven't pulled them apart to even see if there is a midvalve in them. But assuming that they didn't go back on design I'm pretty sure they are in there. Damn... I need a manual!

You may want to, um, uh, ride them first before saying they are harsh.
Gold Valves are in the base valving. This means where the compression adjuster is, to make it simple. The midvalve and other goodies are up on the rod / within the cartridge / up around where that there bladder is, blah, blah, blah.
If you feel the need to spend $150 on Gold Valves without even riding the forks, then you and I need to be business partners. You handle the finance, and I will handle the spending.
I doubt a manual would break it down as far as you are talking about. It would be nice, though!

The only reason I referenced Gold Valves is... EVERY tuner I have ever talked to says you need them. I never said I was gettin' 'em. And I am definately going to test thoroughly before making any kind of modifications to the forks. But I can almost guarantee that the shim stack will have to be modified. After all... these were designed for MX and I ride woods.... yes, almost exclusively. So, if they bottom out on a triple.... big deal! Not my cup 'o tea anyway.

Good job, KAY DEE EXER.
Did EVERY tuner you ever spoke with also just happen to sale them and / or have them in stock?
Good job on testing everything before fooling with it. I think it would be good to have a baseline to compare to.
If my forks ever bottomed out over a triple, then I would tell whoever was riding my bike to take it easy.

I asked mxtuner about woods setups for the KX forks. Note the midvalve is disabled with a particular/certain washer placement.
Note the concern noted on this thread is KX harshness.
Note, too, the suggestion of gold valve stacks:

I just read that. Yup, that's him. I called his desk, then walked over to his office. He's out to lunch. (Like Always!!!)
Anyway, I'm sure he finally said the heck with it and that's why he took it to Race Tech and paid the man. When he gets back from lunch, I'll check with him on the mid-valve situation and see what he told the tech he wanted. What ever that was, that's what I got, because a few weeks after he got his back and I tried his bike out, I was down there with my VISA card.
