Those bikes are Look'in Good Stev-o !! 
Do you think you might have just a tiny bit of sediment in the bottom of your fuel tank and it lightly flows into your #1 carb.. just enough to get between the float needle after sitting ?
Thx Bill...that could be possible but I think most likely a sticky float valve caused by old fuel. I dont ride it much during 100 degree summers, but Fall is here! And the local gas station now sells ethanol free fuel, will use it as much as possible to help as well.
