Dave, I'm not sure about the CB1100, but on my K1200RS it will show oil halfway up the sight glass when cold (as recommended), and then empty after the bike has been ridden. It seems to take hours for the oil level to come back up, leaving more than one owner to panic and add oil, resulting in an overfilled crankcase. In 19 years of ownership, I've learned to ignore it and just keep current with my oil changes. If I ever see the oil pressure light come on, I'll worry.
