Good lord, man! Don't use some ghetto cover on your Busa! Give it the protection it deserves with a Cycle Shell:

NOTHING touches the cycle, so you won't end up with scratched paint or any of that BS.
If you want something to TRAVEL with just but a regluar cover. But if you want it for protection at home, the Shell is like a little garage for the bike.
