Just ride it and see what you think.
The bigger engine acts as an air pump pulling more air across the jets, picking up more fuel in the process. Overall you might end up needing to lean things off a touch. Maybe down a size on the pilot/needle diameter. Maybe half a clip leaner.. a size or two down on the main.
I'd just ride it first.
