I am busy rebuilding the forks on my 92. I notice it has what appears to be Racetech fork springs, but the spacer tubes look WAY too short when I compare it to this image I found in another thread. Top spring is Ractech, middle is stock:

Does anyone have measurements handy for the following spacers:
  • Stock
  • Racetech
From scaling the image I calculate about 52mm for the stock spacer & 164mm for the Racetech. Am I close?

Sounds close. That looks like a picture from Radare's thread and he may have a better answer.

I finally found the Racetech info in an installation document on their website. The spacer length is determined by the amount of preload you want on your fork. Mine is set to 10mm, so I may cut new spacers and bump that up to 20mm. The forks also has Racetech's fancy Gold Valve Emulator installed. Everything appears to have been done according to the install docs, so I lucked out!
