I am trying to build a fork that is soft/plush enough for my use, meaning that I use the whole travel in the typical terrain (rocks, roots, slow speed) that I ride. I would like the fork to do this when I have it in the middle of the adjusting range (10-15 clicks compression). When achieving this, I will be able to actually use the adjusting range of the compression clickers and pfp. When I started out, I used the pfp at minimum preload, as well as the compression clickers all backed out. The forks were still too stiff for my use.

I am quite pleased with my latest setup. I have polished the springs and the lower fork legs, rebuilt with SKF seals and Intec bushings, softened the compression stack and installed 1.0kg/mm PFP springs. I presume my compression stack would be too soft for most people, but I am a old and slow racer If I get faster, I can just put back a compression shim or two.

I ran 15 clicks compression and PFP all the way out in this weekend's race. When finished, I verified that I had used all the fork travel, without noticing any hard bottoming during the race. When riding, I felt the forks were plusher than before, and responded well to all the rokcs and roots (at my pace). In other words, I am close to where I planned to be.

Tomorrow I'm off to a MX club race, the setup there will be PFP 3-4 turns in, 5 clicks compression (or there about).
