It's not a Honda part, so whatever the Honda manual says is not valid. Progressive made the thing, I would go by what their documentation says.jtpipkinjr wrote: ↑Sat Feb 22, 2020 12:18 pm1990 GL 1500 SE, progressive states 2 oz. honda manual states 4.7 oz. some on you tube state 10.5 oz.

Yeah … If Honda even addresses rear shock fluid for a GL1500, it's only the one side and not at all like the Progressive 416s. Even the earlier OEM Honda GL1200 rear air / spring shocks that use same seals as Progressive 416s is different from Progressives.WingAdmin wrote: ↑Sat Feb 29, 2020 3:26 pmIt's not a Honda part, so whatever the Honda manual says is not valid.

With Progressive 416s, the shock body is sealed, you don't actually change the oil or fluid in the shock absorbing cartridge itself. You are only adding back the 2 ounces to the air cannister part to provide lube for that seal.
With the OEM GL1200 Honda shock, pictures I've seen show vent holes in top of the shock catridge so then you may be putting fluid into the shock part as well as air chamber.
