fuel capacity

  1. Fuel capacity question.

    VTX 1800 Tech Board
    Everything I can find on line states my 2003 VTX1800C should have a 4.49 gallon fuel tank. If I fill my bike when the light comes on (about 100 miles), it takes 2.6 to 3 gallons. I've never tried running it to naught. My gut tells me this is a 3.3 gallon tank. Any thoughts?
