Doug managed to get a couple of hp by taper boring the carbs so the air enters them a little better on long manifold bikes.

The FCR carb kit should have came with its own velocity stacks. For max power you will have to install the Malossi short intake manifolds with split carbs (as Chris has already said). You could however easily remove the air box and install a set of pod filters to make a few dyno runs. I would look for a spare OEM air box on
eBay Motors - Autos, Used Cars, Motorcycles, Boats, Trucks, Parts, Accessories, RVs and Other Vehicles as you will have to trim your stock one down to allow just the battery, coils, power modules, etc. to be retained. The last 900SS I did with this setup gained 4hp but lost 6ftlbs of torque. Although this bike was mostly stock and nowhere near as highly modified as yours. Its definitely worth a shot and more economical than the individual carb set up. No doubt, as Chris has already stated, you will need the short manifolds, split carbs and pod filters to make max hp & torque all the was to RPM red-line.
