FAC dampers Le Mans 1000

Anyone on here got FAC fork dampers?
As they’re upside down compared to the original bitubos do they need more oil ?

Fitted them to my 1000s, Â (same forks I believe), can’t remember the exact amount, Â Gutzibits sold me the parts and gave me the amount of oil, Â might be worrth giving them a bell, (forks are considerably lighter with the fac internals).
