Aahahah, 1985? 1965 more like. Anyway, the Laverda manual says 300cc, but the Marzo leaflet says 400. Guidance please!

Don't much matter as long as the damper mechanism is under water, people will no doubt go on about adjusting air gaps etc.... split the differance and put 350cc in each leg ?

Fair enough. Don't want to reduce the air gap too much, that's for sure. Rebound damping not much in evidence, will have to return to this one in due course.

Either the dampers are clapped, you're using water as a damping medium or there's no oil in there at all!
RGS I assume.... my factory manuale di riparazione states 240cc SHF150(whatever that may be)/side. If the damping doesn't improve, use thicker oil, 15 or 20W.

Dow Corning makes a synthetic 150 wt oil that's an SHF150. Now that would be a plush ride ... if you weighed 1000kg. Might be a bit on the heavy side, even for an RGS.

Have an each way bet. Put 300cc in one leg and 400cc in the other

Serious answer: I never noted how much oil I put in, I always measured it with springs out, fork compressed, 150 - 170mm from top, both sides equally, please...
easiest way, but make sure the bike does not role off the center stand and make sure you lift and compress the fork several times after refill to get the air out of the lower part...

Quite possibly, but I can't be arsed to fix this properly right now- clearly emulators are needed. I hated the forks on my 180 until I did that mod. Thing that really irritates me is watching the forks move front to back over little bumps as I'm riding along- no up and down movement at all.
Anyway, the action is better with new oil, soI'll leave it there for now- bigger fish and all that...

Reggie,
Sounds like worn sliders/stanchions! Once the stanchions dig into the internal bore of the sliders, these are quite reluctant to move smoothly. Takes a larger bump to even budge them.... too much friction! But perhaps the forks are only slightly twisted, or you've got a bent stanchion. Either way, will need a bit of disassembly to find out.
