What that means is the fingers are moving too FAR
So what you need to do is determine this:
Do/ did the fingers really need to move that far to release? If so, you have a clutch problem
If not, then your hydraulic clutch system is simply ABLE to move the linkage that far, and you either need (as I mentioned earlier) a smaller master or larger slave, or to change the mechanical ratio, which is probably difficult/ impossible
I wish you'd keep this in ONE THREAD so we can follow what you are doing. Is this a bell/ fork/ clutch combo THAT DID WORK or is it a new build? You may have something weird like a binding pilot bearing, bell misalignment, ???
