To right 41s are to big, basically a good smoothbore carb will flow 20% more than a CV carb, so to match the flow of the 38mm CVs you will probably find a set of 35mm flatsides is the max you will need. Also bear in mind how much power the 900SS makes with the same 38mm carbs and airbox setup.
Its the head and inlet tracts that are the restriction and as mentioned some good flowbench work should deliver good results.
Just let me at Senna3's 675 with my air grinder or maybe we can get the experts have a go over the winter.
