the range LTR gave me when they serviced my Marzocchi 45 fork (07 EC300) was 110-130mm.
Old Scotty's dirt bike spares tutorial recommended 100-130.
I have 2 different manuals for the Marz 45 and one says 90 and the other says 90 for moto and 100 for enduro
I just serviced mine and set it at 130, but I am bottoming out (too much air), so next time I will try 120 or so (a little more oil).
Here is a vid of my redneck fork oil level tool:

I say "brass rod" in the video but it is actually a brass tube. I suppose plastic parts would work but I used a metal tube and metal "crossbar" so the weight would help the tube stay upright when setting the oil level
