Or revving the engine out higher, which usually means a powerband shift.

For the sake of curiosity I do have a 32mm carb, and CCW ran a 32mm carb on their land speed record bike as well, but that bike also had a custom cam profile, high compression, and obviously head porting that also revved out past 9000rpm. For road use, a 30mm smooth bore carb is plenty big enough for a ported head on an otherwise stock engine. My bike happily winds out already with the pumper carb, which is just like the stock unit, but it feels a little restricted up top. Once I get done with some in depth maintenance on my VFR the Hawk is getting switched over to the PWK.
