I found a length of copper 1.5mm twin cable stripped that and stuffed that down there followed with air hose.

I used a length of that thin strimmer cord for crap electric strimmers, not as stiff as wire.... worked well

A gentle blow-through from the bottom (with a bicycle track pump - hand operated so much more controllable than an air line) cleared mine, after a bit of poking with wire and nylon that was too thick or stiff to go past the bend near the top of the drain.
Somebody suggested guitar strings are good, but the other half would murder me if I abused her G string...

Guitar string was what I used. Worked great. I would however suggest a medium gauge d string. It's wound and provides a little more friction.

Turns out that if you can blow through from the bottom like I can then the exact note isn't crucial...
I have this very job to do Monday morning on a Honda dullsville, probably just vacuum pump it out, then throw some dry fuel in, the owner has mentioned that it has happened before, so will have to check the drainage tube is clear
V good lol!

Yeah sorry about that. I was meaning drain the tank at the lowest point to remove the water. Also replace the filler cap seal.

I know the cap seal is fine because it keeps the water in place until I open the cap to fill up, at which point I get to watch it trickle into the tank. Or at least did until I blew through from the bottom of the drain to clear it.

For anybody who cares (that'll be me then), I've just drained the tank to be on the safe side.
After 34 miles with the low fuel light on, I tipped about 3.5l (rather more than I expected/hoped) of clean petrol out of the tank (having removed the filler cap assembly.
Using a syringe and some tubing, and with my partner holding the tank upside down (see, I was right not to cause trouble by abusing her G string), I sucked about another 100ml from the depression (well, it's a depression when the tank is inverted, I suppose it's a protrusion in normal life) round the filler hole. This included perhaps 10ml of slightly milky water that's now sitting in a layer below the last of the petrol in a plastic bottle I had handy.
I'm now waiting for the big o-ring to shrink back down in the sunshine so I can reassemble the filler, then I'll throw in the 5l of 95 octane I just bought along with the clean drained petrol and a dash of meths just to mop up any remaining moisture and go for a ride to flush things through and fill up properly.
What have I learned? I can probably get 50 miles with the warning light on without having to panic too much (either that or the fuel pickup is way high in the tank for some reason). And the amount of water that gets in when the filler neck drain is blocked is pretty small, so if there's a next time I'll just toss in a bit of meths and keep riding.

That was quite a lot of work for 10ml of water.
At least we learned something.

An hour or so of messing around against a couple of minutes throwing in a dash of meths. But 100ml of water risks phase separation of an alcohol/petrol mix, so I thought I ought to check.
Most interesting bit was tipping out nearly 4 litres of petrol after 34 miles with the fuel light on; that makes for 3 litres in the bottom of the tank after the quoted "22 litre usable capacity". One of these day's I'll have to ride further with a can of fuel on the back...
