In my experience open carbs are worth about 1.5bhp at peak more, but cost about 2 bhp anywhere under 10,000rpm.
Up one size on the main jet is about right if you go to open carbs.

b; open carbs look really cool
c; open carbs are the HRC way
d; if you're racing then open carbs mean jetting for the occasion isn't a ton of work
e; carbon fibre...............
