One of the problems with my recently purchased Tiger is that the fuel gauge doesn't go above half even when the tank is brim full. Fortunately it does work for the bottom half! Both tanks do appear to fill.
Any suggestions?
Faulty fuel gauge/tank sender
Hi Pushrod,
Check your voltage regulator. The reg supplies power to both the temperature and fuel gauge. Any problems with the temperature gauge as well? Also check your level sensor in the tank. You can also confirm your gauge by using three resistors to simulate empty, half and full, but I can't remember the values (maybe someone can confirm them).

Just to expand a bit on what Robin has said, I wanted to be sure you were aware that he is referring to the voltage stabilizer/regulator under the dash, not the one in the engine bay. This stabilizer/regulator provides a more or less constant reference 12volts to the temp and petrol gauges.
Also, if the gauge does not go to full scale when you do the test that Harry recommends, it means the stabilizer or gauge is bad as has already been said. If the stabilizer is bad, then both the temp and petrol gauge will not read correctly, again as already highlighted.
You can confirm the gauge is good by connecting a 9 volt battery to the gauge after disconnecting the dash wiring from it. Positive connection to gauge input and negative to gauge case. It should read 2/3 of scale (i.e., 9volts is 2/3 of 12 volts resulting in a 2/3 of scale reading). That is about 8 gallons on the gauge. BTW, same thing works for the temp gauge and 2/3 scale is about 200 degrees F.
