Is this something new or has it always been like this? Are the tires at proper pressure? Have you changed the exhaust or made any other modifications?

Holy Crap.....that is bad.....

I get (in miles) 125.......

I would be looking at (easiest first) your Throttle Position Sensor adjustment....
If you haven't done this, there are som tutorials on that in Tweaking and Tuning....
Also, check the Secondary Throttle Position Sensor as well....

While you have the tank up, check your air filter, if its filthy, get a new one, and maybe invest in a K&N or BMC or similar washable unit....

If you are feeling keen, take the tank off, flip it upside down and remove the fuel pump, and then disassemble it, and clean the pickup mesh to make sure it is running clear. The main filter can also be replaced (at a cost)...but the pickup is usually all thats needed.
Get a good quality fuel system cleaner/condtioner and use that over several tanks to clean any minor gunk from the injectors.

Fill her up and take it for a run once you have settled those things, and see how it goes.....

.....also, with that much fuel being burnt, there is a possibility that you engine oil could be contaminated with unburnt fuel via piston blow-by. So, the instant you have that fuel usage problem sorted, change the oil and filter.....

I might no' be a smart man Jenny....but i can pain' ma copper colored bike a dif'ren color.....

that's way worse than you get. I'm fairly happy with the throttle and get 100mi or so before the light comes on.

What gearing? What kind of riding?

Really, if you are gonna lift the lid to do that, setting the TPS is a 5 minute job while you are there...
Saves having to get back in there later.....

OK tootling around on country roads at 80/100kph (50/60mph) you should get +-5.6ltr/100km, You can do the conversion. Flogging the ass of it though twisties in 4th chasing GSXR/Fireblades and going full bore on the straights (250kph in 5th) you will get roughly 10.5/11 ltr/100 which equates to +-100/110km or 60/65miles before the light comes on from a really full tank.
OK No chance on the straights but they take one hell of a time to catch up after the twisties. (Or so a friends tells me) Hope that helps.

...just wondering, my 2003 model had an issue with a post-production coating on the inside of the tank completely clogging the fuel filter and pickup, and consequently, the injectors also blocked pretty badly, they squirted rather than sprayed....

Once the fuel filter was taken care of, and the injectors were professionally cleaned with an ultra sonic cleaner, things improved a bit, but, as was found to be true, the combustion chambers were full of carbon, and a good hard run on a dyno, using Subaru Upper Engine Cleaner, and away she went......
It was that bad that before the cleaner was used i was getting 97hp.... and once it came clear, and it was like an explosion of the most amazing shit came out the cans, it shot up to 121hp.....

My warning light was coming on at around 160 klm, I was chaning my oil and so decided to do a quick flush and so poured in a can of Liquimoly engine flush, yesterday the warning light came on at 207 klm. The Moly cost me $19 money definitely well spent as far as I am concerned.

I'm not saying it is going to fix your problem but it certainly did wonders for me.
