Why would anyone want better acceleration on a big, fast bike anyway? You're already at the wheelie limit until 4th gear... Dropping one from the front of a 600 maybe, but they're pretty close to the wheelie limit these days too... My 06 GSX-R600 will try to lift the front in 3rd if I hit a very slight bump in the track when I'm using full power... It won't quite do it, but it sure does get light.
