For carby models: 185 main jet is the go.
or 220 if blown, BUT the sporty in question is a 2013 so i recon its EFI.
Ran a 190 main in my 96 sporty sport 1200, a dyno operator decided it was too much and took it out, bike wasn't as quick off the mark, pissed me off at the time, miss that bike, was my first harley.
I achieved much quicker throttle response/acceleration by also making a new pump rod ~1.2 mm longer.
