How are you working your mpg out mate? You're not filling up when the light comes on and thinking you're putting 16L in when you're only putting about 8 in are you? Might be your light coming on early and you've not realised - don't laugh, I've read that happening before!
Taking capacity of tank, cost to fill, noting that when the light comes on, it's at just about a fiver's worth of fuel. Also using the trip meter and offsetting that with cost to fill to max. If that makes any sense.
I ran it dry recently (to my shame) and the trip meter still read less than 100 miles.
To answer other questions:
Bike has done 42000 miles.
There are no fuel leaks.
Haven't noticed any kind of fluid coming out of the exhaust.
Everything else is getting looked at in January.

So to confirm:
Look at miles
Divide miles covered by litres of fuel put into tank.
Multiply that figure by 4.54
That's your mpg?
