So I've read the manual and run searches on this topic - still lookin for the easy way.
The manual describes a labour-intensive removal and disassembly of the forks just to fully drain and refill each leg. Regardless of how attractive the prospect is to spend days on the job and cursing the lack of special tool "Z25C", I was hoping for an easier, quicker method.
Is it possible to just unscrew the adjuster assembly low on the fork legs and pump out the fork fluid ( front brake on and repeated fork compressions) ?
For the refill, is it possible to unscrew the main fork leg cap (with the legs in situ), slowly bring weight onto the front wheel which then pushes the suspension mechanics out the top and then pour the new fork oil into whatever open space is available at the open, top end ?
The specs recommend 520cc / leg. What's the general experience - reload the full 520cc or just refill the same volume that was drained / expelled from each leg ?
I'm quite happy to admit several libraries could be filled with what I DON'T know about the GRiSO. To paraphrase Mr Dylan : " Only a fool would try to hide what he don't know to begin with .... "
