This week, I installed Hyperpro fork springs and I am very pleased. I have ridden about 200 miles so far. It goes over bumps much smoother and feels better in corners. The old springs had a 2" resting sag with the preload at zero and the new came out to 1 1/4" with 3 rings, just like the specifications said it would. The old springs were shot and I can't believe how short they are.
A fork seal was leaking , so I did a complete rebuild. The bottom bushings had about 1/2 the teflon worn off, so I replaced them. I used a 2" OD tail pipe with .050 thickness to drive the two top bushings home, 2" pvc pipe to drive the seal in, and a 2" pvc coupler to drive the dust seal in. About $10 for the new special tools!!!
Removing the oil seal is interesting and unlike any fork I have serviced. I tried one method by filling the fork completely with oil, placing the fork under a sturdy shelf, with a big socket on top of the fork not to damage the adjusters and a floor jack underneath(don't have a press). It pushed the seal up just enough to pry the seal out. I think just putting the fork tube in a bench vice and slide hammering the seal and two top bushings, with the inner fork tube, is just as easy. However, you need the tailpipe to drive the two top bushings back in on reassemble.
Anyway, a good and inexpensive upgrade. Springs were $169 with a liter of 15w oil. Wish I had done this sooner.
