Another question.. 26MM to 28MM?

Ok so you guys ID'd the carbs for me. Now I want to swap out my 26MM's for the 28MM's. I checked out the jets tonight and the 26's have 110 main jets, the 28's have 120's.
I want to order the rebuild kits, I might be able to pick my jet size so should I change them or leave them alone?
Stock 1978 KZ-1000 with 4/1 Kerker and POD's. It looks like the baffle is intact, I may at some point try it sans baffle to see what its like if that makes a difference.
Is there anything else I need to make the swap or is it a direct fit?

Thanks,

Ron

my 77 kz1000 has a baffle free 4 into 1 vance and hines with pods. i run the 28's with 120 mains and needle at clip #3. it seems to do fine...for what its worth.
