Measure the header temps...that could at least tell you if it's related to a certain cylinder.
Call Hudson Cycles and see if they can tell you what the stock jet sizes are for this bike. They are a Kwak dealer and have that information.
Also, if you suspect a lean condition and you're sure your carb settings are correct, try lightly spraying some WD-40 around each intake boot, one at a time and listen for a rise in RPM's. If you get that then you've found an intake leak. Check all 4 one at a time in this fashion.
The pod filters and no jet kit is another concern of mine in this scenario.
You may want to go more on the air mix screws and possibly raise the needles a half a step to start and go from there.
After I did my jet kit, I ended up setting mine at 4 turns out.
Worse comes to worse, PM me and I can head over sometime this week....I'm one town over and have all the tools.
One last thing--> Is your mom's lady friend hot?
