As for the plugs, definitely no gas. The are dry and smell like a new plug.

It was running about 2 months ago when we were in NC. I started having the "not charging" issue and didn't have time to fix it before we moved. Now we are in NW Florida.

As george said no fuel thru the mains using BS carbs means no fuel to the pilots.Your carbs have a passage from the main jet to the pilots, is it clear?. Do your BS carbs have the plug that covers the access hole that the pilot jets are in? If not get the metal covers and O rings from Kaw or use the rubber covers from Suzukis with BS carbs.

I'm not an expert on street bikes but this sounds to me like a pilot jet problem, but kinda odd that all four pilots would be pluged.
An old trick, Remove the plugs out of cylinders 1 and 4. Pour in a small (and I do mean small, maybe a table spoon in each cylinder) amount of gas directly into each cylinder replace the plugs and try to start the bike. You'll have to do this quickly.
If the bike tries to fire then you know the ignition is ok and that the problem is in the idle circuit.
If you changed the petcock maybe you got some crap from the tank into the fuel system and plugged up the ptlot jets.
With the right screwdriver you might be able to remove the float bowl from either carb 1 or 4 and check the bowl and pilot jet.
Believe me always check the obvious frist. The guys on this site have been helping me shoot an idle problem for a couple of weeks. Wiredgeorge suggested I check the return spring and it turns out my problem was the throttle return spring!!!!

Odd that after performing okay for 10 miles all carbs would simultaneously fail in some manner whereby suddenly no fuel mixture is available to be sucked from any carb into any combustion chamber. Especially where floatbowl fuel level is presumably correct in each carb.
Many enrichener circuits are designed to function only when the throttle is left completely closed (absolutely untouched) during the initial cranking in a cold startup. Has start-up been attempted with choke fully engaged and without touching the throttle grip?
If not already done, could as a last resort (before disassembling carbs) experiment by spraying some starter fluid into the air intakes while attempting to start the engine.
Good Luck!
