OK, I have a 2001 WR426F and it has a leaking fork seal. I have bought a new set of seals including the dust seals also. Here is my problem, I have never dissasebled upsidedown forks before and I assume these are filled with nitrogen also, there is a schrader valve on top of the forks. Any tips and how do I refill the nitrogenand dissasemble the forks. The bike is working fine, but evertime I strap it down, it leaves a puddle and I need to get this fixed before my next ride. Appreciate any help or tips on avoiding trouble, springs flying. Oh, and how much oil in CC's does it require when refiling and the viscosity and where do I get the nitrogen and mow much? .
