Advice please

Here's another one for you to mull over! Is there anyway to recalibrate the fuel sender? After 110 miles the gauge still reads full, then the light comes on at half a tank at 140 miles, then time for a refill at 160 miles! Is that good mileage? I don't ride like a prat as I don't know how to

As an electronics engineer I did consider making a circuit to compensate for the non-linearity of the fuel sender, but took the easier option of getting used to it instead. :lol
Assuming you get mid-fifties to the gallon you should be able to get 200 to 220 miles from a tankful, the reserve light typically comes on very early though... I was sweating bullets the first time I exceeded 40 miles with it lit, but do so quite often now. A fill-up then is normally 18 or 19 litres which cuts down on time wasted at petrol stations.
