Fork upgrade with emulators

I`m searching for information concerning upgrade my forks with emulators.
I assume these is something I cannot do myself ?

What company does these in Europe and US ?
Do I need some new parts ?

Somebody have some technical information concerning emulators ?

Here's a good topic with pics from another Kawasaki forum. plus a couple of Racetech links & Racetech video.

If I understand these correct can I install it with fork installed one the bike....

Why is not everybody install a emulator in each fork ? No brainer ? or ?

From what I've read, you have to disassemble the forks & modify the damper rods, so you have to remove the forks from the motorcycle.

Why isn't the upgrade done more often? Possible reasons: Cost. Not a simple install. Not commonly known.

Yes I see that, but you are able to adjust without taking off the forks.

These is maybe a project for next winter

I don't know how to adjust them. I haven't read that much about them & haven't read anything recently.

He explain it in the youtube video.

Race Tech emulators can be adjusted by taking off the fork cap and pulling the preload, main spring, and emulator out of the fork.

There's different emulator springs you can use to adjust the emulator and the preload can be changed as well.

***with the preload, I played around with mine using PVC pipe cut to the length I wanted to test. Once I found one I was happy with (riding a few miles to test) I cut some steel tubing to that length and used the steel one as my "permanent" pre load.

You need to drill (and deburr) some additional holes in the damper rod. Obviously a good time to do a thorough rebuild of the fork assembly.

Agree with your reasons on why it's not done. Absolutely worth the cost however

Yes, Hoyt Clagwell in that first link is the one who got me to thinking about making the upgrade. he's a big proponent of the cartridge emulators & has suggested them often over at that forum. Does anybody else make a device like that? I've never looked further than racetech. hee.

Gordone, here's a link about adjusting the racetech gold valve emulators. Racetech >> Tuning Guide .
It says the emulators have to be removed from the forks to be adjusted, but usually this can be done with the forks still mounted on the motorcycle.

I first installed Race Tech Cartridge Emulators and Race Tech springs on my '73 Z1-900. I was so impressed with the results that I also installed them on my '78 KZ1000. I found the task of installation fairly easy and straightforward.

Did you use much time on tuning ?
1. Tuning the valve ?
2. Findings correct preload on the spring ?
