do you have the bike on a rear stand or just holding it up? If on a rear stand, drop it off the stand, hold the bike up straight...you know it is straight when it is super easy to hold up. Then check the level again. If it is a little too high, find something to suck out a little oil through the fill hole.
If it is still near the middle of the sight glass off the stand, you are good to go.
