So about this wole wet sumping thing...
After learning about it recently, I checked the oil tank on my FLSTF and... the oil has drained into the case 
What is the easiest way to get the oil out of the case considering there is no case drain? I'd rather not blow it all out of my breathers and make a giant mess when it's time to get the bike going in the spring.

I put a slimline oil pan under my 92, fire her up and let her bleed. If you start her up once a week or so and let her warm up, she should stop puking unless the ball check seat is etched badly.

In other words you're saying it's 93 or later top breather?
Pull the plugs and disconnect the white wire to the coil.. Crank the motor over for 30 seconds.. let the starter cool down for 15 minutes.. Crank the engine a second time for 30 Seconds.. You will need a good battery to do this.. After letting the starter to cool down.. Put the plugs bag in and start it . You should be ok.. By cranking the motor over like this the scavenge side of the pump should return a good amount of oil to the tank so when you start it it won't starve..

I assume your bike is in storage for the winter? If so, no worries it is a once a year event. Do as "98" stated or just put the pan under her for the first start. The biggest issue is when you do not know it is going to happen and it surprises you, makes a mess and you post up to the Forum why is my bike puking oil. Once you know it will happen, pick your preferred course of action.
Now if it is doing this after a week, you might want to investigate further. Good luck.

You've got a shutoff on the petcock, leave it closed and bump the starter.
The oil will return to the oilbag.
If it happens again after sitting a month clean and or replace the ball and spring in the oil pump.
Be happy it's not a bottom breather.

Don't know why the OP isn't stating what bike he has but I looked back in his threads and apparently it's a 94 Fatboy, top breather.. If he does as I said he'll be fine or as you said Dan, he can just start it or whatever.. I personally don't like to just start it, I like to have a little oil in the tank..

Empty the tank is a oil pump ball check crack from a moron with a sledge hammer not a tin 1 oz re seating the ball idea
we use a bore scope and clean the ball hole to see if its been destroyed - oil pump is the only fix if it is
