Heh, if you have much tank slappin going on with the Busa your doing something really wrong, or something is wrong with your bike. If you get a BIG Slapper though like when you fudge up landing the front end... There isn't much out there that can help you. Otherwise day to day, yeah, what the others said, Increase oil weight in Damper or buy a premium aftermarket damper like Scotts, or Ohlins and call it good. But really I have only been longing for a stronger damper once, and yeah... it's when I got it all wrong...
Relaxing and lettnig the bike work is probably one of the best ways to settle your chassis though, and Getting into the throttle hard... Both will ease a burly slapper...
