1100et fork oil levels

[Spelli]

Just come to top up the fork oil after replacing the seals on my 1980 1100 et and found the manual gives 2 different specs and levels

The manual states a level for  “E-01,  E28 and E-30.”    Of 238ml / 216mm 

and a second level of 252ml / 193mm  for “The others”

I can’t seem to find from the manual what these 2 different specs refer too. 
 

Any help would be appreciated.

Thats why they quote air gaps! Less air gap = harder spring effect and that can be felt!

yes thats true but in this case of 40odd year old forks your not gona feel the difference of 14ml of oil.

But it's possible that you would feel the effect of the 25mm height difference at the bottom of the stroke.

Wheres the 25mm height come from ? We are talking of 14ml of oil. That wouldn't raise the level that much.

Thinking it is the oil level difference of 23mm between models

Sorry 23mm, it's in the screenshot from the manual at the beginning of this thread so I guess 14ml would have an effect.
