Also, you don't match jets and accessories. You need to run the bike and check the plugs and their color. Since pods can be more restrictive than the original air box, and exhaust systems may offer less scavenging or more, depending on many factors, you may actually need smaller jets, or other intake modifications.
Run the bike, not too hard. Check the plugs....then decide on which jets you may need.
You can be rich at idle, lean at midrange, rich at full throttle, or any other combination.
The best way to rejet is to have the bike dyno tested, using a wideband O2 sensor. then they can tell you exactly where you are are lean or rich.
As far as pods, on a 4 cylinder they are very difficult to tune properly. The center 2 carburetors get supplied by warmer air, and at a different pressure, the the outer 2 cylinders. To get this right, you have to have the 2 center carbs in a different setup the the outer 2. It can be done, but it is time consuming, and expensive.
Pods don't really breath better than the OEM airbox as the pods have much less surface area. In addition, the stock airbox is a plenum, which provides relatively still air of the same temperature and pressure to all 4 carburetors. A better air filter on the stock airbox will likely flow better than any set of pods. Pods will never offer the advantages of a plenum either.
