V7III Ferk Eryl measurement confusion

[elrealistico]

So I am banned from riding for a few weeks due to medical stuff. So decide to change the fork oil on my 18 V7II Special--Kalifa forks.

1. draining oil, appears to be maybe 60ml (measured in cup) of dirty oil. This seems very low, but AFAIK its what was put in there from the factory/dealer 7 years ago

2. I have the shop manual ("filling Oil" pg SUSP-186) theres no doc I see anywhere to say how much goes in, and the measurement itself is confusing.
I do not have the legs disassembled, just the spring out.
So where is the measurement taken? MG references the top (long silvery part) and bottom (part the wheel and brake bolt to ) as "sleeve"

Text from Manual--
Place the sleeve upright in a vice fitted
with protection jaws.
· Compress the sleeve in the stanchion.
· Pour part of the fork oil into the sleeve.
· Wait some minutes until the oil fills all
the ducts.
· Pour the remaining oil.
· Pump out oil a few times.
· Measure the air gap between the oil
level and the rim.

There's a pic too.

SOOO--Is the measurement taken from the tippy top of the long silvery bit that goes onto the triple trees, OR from the top of the bottom part the long silvery bit slides into and has the wheel/brake bolted to it?
If the latter, how can it be measured with the long silvery tube in place?

Past times I have done this on other bikes there was a specified amount of oil/ATF, so this is a bit weird.

TIA for any insights!--Matt S

Jeeezarse…!
They make it hard don’t they ? Why not just say…
Empty out the existing oil.
Leave it upside down after pumping the slider through it’s normal operating limits.
Place the fork/slider combination upright.
Pour in X CC’s of oil.
Should be a slam dunk.

In most of the manuals I've worked with it is measured from the top of the fork (long silvery bit) to the top of the oil in the fork with the forks compressed (no spring in place yet).

But absent specific instructions from Guzzi or the fork manufacturer you may wish to try it multiple ways until you find watch matches the spec.

And though it's not uncommon to have both a capacity and a fluid level spec it's possible to have only one or the other. If I were only to have one the level is most important (as long as they are clear how to measure it).

You might do an internet search. When I replaced the seal in one of the forks on my V7lll I found the amount to add by volume online but I don't remember where. The way described in the manual made me unsure whether I would do it right or not. The directions in the manual were a bit vague if I remember correctly.

I tend to overfill the fork leg and then adjust the level with a syringe and hose cut to the right length for the free space recommended by the fork manufacturer or spring manufacturer. Those specs can be hard to find. Last time I did the Breva 750, I checked the level before removing the oem oil. My new Hagon progressive springs called for a different level. That's where I set it going back together. It all seems way overcomplicated, doesn't it.

Good luck!

It’s 120 M. M. From the top without the fork springs.

[Off @ 90]

The oil volume approx 400ml per fork. At 60 ml would equal virtually zero dampening ?? Are you sure all oil is out ?

Myep. I was misreading my measuring cup--repurposed from kitchen duties with worn markings. Capacity is approx 400 ml per leg. Set level 120mm below top of tube with spring out & tube pushed all the way down, using my cheapo vernier caliper depth gauge, all good. I did go to 10W oil, to line it up with the EV and because I wont be doing any suspension upgrades, my middle kid will get this bike in a couple years, hes way lighter than me and will do fine with the stock
