Thanks for the links Pleiades, it helped me setup the actuating rod correctly again.

But the main problem I had still exist which is that the clutch is not actually disengaging, I thought it was maybe due to the clutch plates sticking and that's why I opened it up in the first place but that does not seem to be the case. I'm sure the clutch plates etc. are all in the right place at the moment as per manual now. To be clear this problem already existed before I opened her up, I first noticed the problem after I changed the oil + filter. Anyone any ideas? I just cannot disengage the clutch even the slightest even if I fully remove the slack of the clutch lever.
