As Mark has already said there's the drain plug - easy to find and easy to do.
Now if your breather/drain pipe is blocked also (as no fluids should sit around the underside of the fuel cap) then do this test:
1: There are two escape vents connected to the "breather / drain pipe" - one is located directly under the fuel cap (a black protruding nipple that fits flush with a tiny breather hole on the underside of the fuel cap that sits at 6 o'clock as you sit on the bike) and a second one that is flush with the base plate that surrounds tank fuel filler hole at 9 o'clock as you are sitting on the bike.
2: To test for blockages simply cover with your finger
one of these two vents and then get down to the exit of the "breather / drain pipe" (should be somewhere below your oil filler sight glass) and blow up through the pipe. You should feel air coming out of the hole. Then repeat by covering the
other vent. If air does not come out of either of the two vents, the pipe is blocked or pinched somewhere along its route.
3: Note that this pipe has a "Y" junction just underneath the tank where the base plate sits for the removal of the fuel pump etc. Hence the two vents when you look from above under your filler cap as if you are tanking up with fuel.
4:Fluids retained around the filler cap suggests tome that it is the 9'oclock vent that is blocked as this is designed to help escape fuel when you have overfilled the petrol tank. Under normal circumstances a bicycle air pump is enough to clear it.
