It may also be too lean at high RPM....like a plugged jet. Not enough fuel to ignite so raw vapors get pumped out. The carb would be the first thing I'd check. Coils on 1100's rarely have an issue.
If it was me, I'd pull them off, clean the jets and everything else, make sure the needles are seated, reinstall and synch.
