Often it's caused by a small leak in the fuel system. No you won't see it leak, it's internal.
Or - It could be the fuel pressure regular's check valve - dirty, worn etc. Clean or replace.
But often it's in the tank - the fuel pump.
The pump has a short rubber hose on it 4" long?- all the aftermarket pumps save a penny or two by using a rubber hose that's not fuel hose. (Inside the tank.) Eventually the gasoline dissolves the hose a little, when you stop the engine the fuel drains back to the tank out that leak. You'll find it turned to a sticky mush!
Make sure you have used most of the fuel in the tank, remove the 8 screws holding the pump in the tank, carefully extract the pump.
Replace that hose with QUALITY FUEL HOSE, clamp it securely, replace. Done. Enjoy!

I appreciate all the input guys! I will try those steps and see what I can figure out. If I happen to pinpoint what the issue is I will definitely let everyone know for future reference. Its nice to have people who actually help each other out. I'm on a cbr 1000 forum and nobody posts anything other than "my bikes the **** because..."
