Put the bike on the center stand and cold, the oil level should reach the bottom line. With hot (expanded) oil it should be at the upper line.
To test how close you are, rock the bike over to the left on the stand. If it's close the oil in the sump should come into view in the sight glass very quickly...
You can always add a few mL as needed.
p.s. the "complete refill" is stated as 2.1L in the manual. Your level may vary (a tad).
