of the shelf aftermarket pistons are around 10-15 grams heavier.
stock busa pistons are 17 grams lighter.
there are some aftermarket ones that can be lighter.
weight is not only issue with aftermarket ones.

So with the busa pistons, does that mean you need to work on the bottom end? i.e does just dropping them in cause balance issues?

no,you don't need to.

zadar I feel guilty for picking your brains

Curiosity question: is this because the weight difference is small or because of inherent balance in the V-twin?

Serious question: what hone do you need to take out of the SV bore for the busa pistons?

if you want to be serious about it and building race motor you would re balance whole motor again.it is correct way to do things.
in real world difference is not great enough to make it necessary ,you can get away without doing it.
you need to hone it out until you get proper clearance.clearance can be found in manual.there is range,pick number in there and go for it.engine builders pick number that they believe will give them best clearance for intended use.and you can't find 2 of them to agree
