Do I need to run the bike with the stock carb and then do the upgrade?

I know this is late, but I tried to replace the stock PC20 with a PZ22, for a straight swap to keep the stock airbox. No dice. Even this tiny increase in inlet size meant the carb would not clear the starter with the stock manifold in stock position. Didn't figure it was worth it to buy a new manifold or spinner to make it work, so returned it.
So I would venture to guess there is no larger than stock that will fit without modifications.
