I had a problem with fuel when my floats were way out from the factory. Would keep getting richer at idle. In fact I had all kinds of problems until they were adjusted properly. Fuel level is very important, you can easily load up the carbs with fuel if the floats are out regardless of main jet size(it wicks up the emulsion tubes) I would take the carbs off and make sure the float height is at 13mm(Actually 13.4 after measuring with digital calipers). I have a G2 as well and once the fuel level was set it was super easy to tune the bike. For your reference I have a 1.5" hole in the top of the airbox, my floats are 13mm my pilots are 17.5's my mixture screws are 4 turns out and I have 110mains with 5 shims on the needles.
I think you might also check to see if your emulsion tubes (The brass thingy the main jet screws into) is not worn and all the jets and tubes are snug. Something tells me some fuel is leaking somewhere as when you have larger main jets you actually have less fuel because the jet size is bigger there is less fuel pressure built up in the float bowl so there will be less leaking wherever it is on your carbs. My guess is the float level is set too low thus overfilling the floats and extra fuel is leaking or wicking out through the emulsion tubes or loose jets.
For fun this is what I would do:
Take the carbs off (no getting around this)
-Make sure the carbs are at 13mm to start. Some of mine from the factory were as low as 11.5! No wonder I had fuel wicking problems!
-Put a stock filter in(I tuned to a K&N too, but it wasn't as good(flat spots) and it was a bitch just to get halfway decent)
-Make sure you have the 1.5" hole in the center of the airbox as per Dale's specs.
-Leave the stock pilots (15 size) in there for now if you have larger ones.
-Put 110 mains in there to start
-Put 5 shims that dale gave you on the needles. If you lost or don't have them you can use the radio shack jobbies but they are about twice as thick so only use 2
-Make sure that the emulsion tube and all the jets are nice and snug. Don't go jihad tightening them they are soft brass, you don't want to kill them.
I had all kinds of problems until I fixed the float height. The asshole dealer who I paid to install the kit didn't do phuck all other than pop the jets in. My floats were all over the place. One, leaking fuel, was at 11.5! Way too low. And another was at 15.5 starving of fuel. There should be a big ass page in Dales instructions.!!!!DO NOT EVEN ATTEMPT TO USE THIS KIT WITHOUT THE FLOAT HEIGHT SET PROPERLY!!!!
My guess is that your float level is so low that the only thing holding back the niagra falls of fuel in your carbs are the needles. Here is how you check the float height with a bad commodore 64 ASCII diagram:
Once you take the carbs off remove the float bowls. You may want to replace those shit brass screws with stainless steel hex bolts (5mm x .8mm x 12mm - Float Bowl)
When you take them off and hold them horizontal it will look like this:
== == == == <-----Top of the carbs
/ \__/ \__/ \__/ \
\_/ \_/ \_/ \_/
You want to tilt the carbs on the side like this:
_
/ \I
\_/I <-----\
I_ \
/ \I \
\_/I <-----\ \
I_ Top of Carbs
/ \I <-----/ /
\_/I /
I_ /
/ \I <------/
\_/I
Now that you have it on it side you can swing the carbs back and forth and the floats should swing freely and without too much pressure you'll notice that they will stop at a certain point when swung so that the floats are closest to the carb body. You must measure this and make sure that the highest point of the float is 13mm from the carb body, when the float is touching but not compressing against the needle valve. Thats why its a good idea to measure when the carbs are on its side as it will swing freely and not compress the needle valve. If it is too low or too high you have to bend the float tab in or out to adjust the float height. The float tab is the part of that is attached to the floats that actually touch the needle valve. Remember all these parts are delicate and only bend the tab in little adjustments. MAKE SURE THEY SWING FREELY. If not you have a stuck float and that will surely dump fuel.
If you're float height is already at 13mm you might want to bend the tab so the height is 14mm to lean up the carbs a bit. Remember, increasing the float height leans the mixture and decreasing float height riches the mixture. Since you seem to be super rich I'd say lean it(increase float height) IF and ONLY IF you're float height is already at 13mm. My guess is that it is lower than 13mm and thus you have fuel dumping into the carbs but check to make sure.
Once the float height is set pop in a 110 main and a 15 pilot for now with the mixture screws 3.75 turns out from seated(base settings) and make sure the emulsion tubes and main and pilot jets are all screwed tight so there is no leakage of extra fuel past these passages. Remember these parts are soft brass so nice and snug is fine don't go crazy unless you want to buy new carbs. See how the base settings go and if you have trouble just PM me and maybe we can talk on the phone as I have the same Gen bike and have gone through the process.
Since your in Florida which is wet and hot you may need a little leaner than base settings but this is a good place to start.
