Hi alltogether,
this is my first post in this forum. Normally I am reading/writing in german (vintage) bike forums. But I couldn't get the help I need so I am trying my luck here.
I have a Rockshox Mag21 fork for my Specialized S Works Mtb. While rebuilding it, I did not only want to change the seals and O-rings, but I also would like to adapt it to my rider weight (~62 kg). Rock Shox has a nice manual, which I tried to attach here.
Following this manual I should choose the following setup:

Following this manual I should choose the following setup:
- softer valve spring (25lb)
- no "valve spring preload", so no washers under the vavle spring
- compression bleed hole with 1,5 or 2mm (depending on cross-country or downhill use)
- no rebound bleed hole or 2x1,0mm (depending on cross-country or downhill use)
- Do you agree with the proposed setting? any propositions?
- How do I know which valve spring I have? I should be able to check that by compressing the spring. The manual says there is a 25lb and a 40lb spring - but which length change should the spring make under this weight?
- Honestly: I do not understand where the compression or bleed hole(s) should be.
- what does this sentence mean (from the manual): "valve plates are a tuning variable. The .005” relief step machined into plates used from 1994-97 improves small bump response"
