If your losing that much fluid then chances are that the slave cyclinder seals need replacing. This is a common fault with the FJ clutch slave cylinder, easy job to do and the seal kit is around £15 - £20.
If he makes a video I'd love to see it done, I've rebuilt mine twice and ended up folding it on the second one shearing the rubber off the seal and pissing all my fluid out on the test ride. Now I have to rebuild or replace the front brakes as the pistons got stuck and wouldn't return as I was riding without a clutch lmao. 14k miles, but time and old fluid ruined the poor thing, and I ended up buying another one to ride while I figure it out.
Also you said the R1 has less clutch leaking problems. Could it be that's not because of a better design but because the FJ is on average five years older making the seal in the slave cylinder simply more likely to fail due to age? I'm wondering since some guys in the FJ1200 facebook group advertise aftermarket clutch slave cylinders for 170 euros which apparently have a better design but I don't think the metal part is the problem, just the seal that will need replacing every so many years. So then this upgrade wouldn't be worth the cost and I'd just use clutch rebuild kits. If however there is a design error in the metal parts of the clutch on the FJ the aftermarket kit may be worth it.
that bike looks awesome and the sound has alot of caractere

Yes i did this plus changed the rubber gasket inside the reservoir and have had no problems since. Thank you!
The clutch fluid is DOT 4 brake fluid?

With all that dirt in your master cylinder I would be re kitting master and slave cylinders, then you won't be constantly having tonre bleed
