I have checked workshop manual for Corsaro today but I haven't found procedure for front fork oil change. Only thing I have found was disassembly/assembly of the front fork and during this procedure was one step draining old oil and one step was filling new oil.
So I would like to ask, if is possible to change front fork oil without complete disassebly of the fork...?
Maybe just loosen lover screw and upper big nut for draining old oil, then tighten lower screw back and fill with new oil thru opened fork on the top?? I'm just guessing it might be done like this...maybe not...
