Foxeye fuel light - adjustable?

[Jamieg285]

Just got to the bottom end of the first tank of fuel in my new bike.  I thought that the fuel light may have been broken, as it wasn't coming on.  I braved it out and kept going, and found that it only comes on when the needle is in the middle of the 'E'.  In fact, if I remove the key at this point, the needle doesn't move, it's already at the end of it's travel.



I'm sure this isn't normal and I'm not sure I'd trust it another 10 miles from the light coming on, let alone the 50 that others have advised on here.

Is there any adjustment I can make to make the gauge/light more accurate - either in the gauge or with the fuel sender?
