Only if the cab is towing the bike.
Seriously though, increasing the carb size won't help. To make them go faster requires a crankcase stuffer plate, a high compression racing head and detailing the porting regarding the piston. Adding a tuned expansion chamber will top it off but your neighbors will complain about the noise.
Contact 'Mutt' for the details.
