welcome, man. those 440's are nice little bikes and it sounds like you're off to a good start and have a plan to follow. best of luck with it.
is that a 2-1 exhaust, and did you put a slash cut on the end? might just be the angle of the pic but it looks bad ass. you're probably going to have to re-jet the carbs from the pod filters and exhaust mods. find out what type of carbs they are, I have a ton of pilot and main jets that might work if they take the same jets as the ones on my kz750.
Edit: i just did a little searching to see if the jets would swap (couldnt find the info) and all the kawi guys are adamant about sticking with the stock airbox on the 440. apparently the carbs are a severe pita to tune and never end up running correctly. to give you an idea, i found more threads on carb swaps than on rejetting the stockers, laugh. conversely, I'm sure its possible to get them tuned, but it doesnt sound easy. also, i didnt see anyone attempting to swap out the air jets, just the primary and secondaries.
