If I am not mistaken, and I may be, my 08 RSV is suppose to hold 5.9 gallons of fuel. I think I read in my manual that when the fuel light comes on, I have about 1 gallon of fuel remaining and I will have to switch to reserve pretty soon after the light somes on. It is true that I have to switch to reserve pretty soon after the light comes on. However, when I fill up, it only holds about 4 gallons. If my tank does hold 5.9 gallons, I should have almost 2 gallons of fuel remaining. My question is do you think my fuel light is coming on a little soon or does the tank hold 5.9 gallons and only 5 gallons is usable fuel? Or do I have 1.9 gallons of reserve fuel? I'm a little confused because I was thinking I only have 1 gallon of reserve fuel.
