Thanks for the reply. Sort of worked it out today, i was undoing that nut on the bottom of the fork but it turned and turned! after some time the penny dropped, long bladed screw driver down the top to locate in the slot to stop it turning. I hope i am ok for a bit more info? not too sure what i am looking for inside. There is a rubber washer/plunged on the bar that is held by the bottom nut, should this be a tight fit in the bore of the fork tube? Its quite slack? not like a bicycle pump, is this right or should it act like a piston? Also, how much oil per fork leg and what sort please. Sorry for all the questions. I have been told there is no manual for this model, is this right? Thanks Pete.
