I just got my 2003 V Star Custom 1100 last week and noticed that I run out of gas at around the 65 mile range. It ony takes 1.6 gallons to fill my tank even though my research shows it should be a 4.5 gallon tank.

Is there something wrong or did the previous owner swap tanks? There are no badges.

It would effect the amount of fuel used, so it won't be completely empty when you fill up. if it is completely empty you have a modified tank and I would be afraid something is stashed in that tank.

The carbs are actually above the bottom of the gas tank. The pressure of gas will fill the carbs till the fuel level is about half full. Then the fuel in tank is actually lower than the carbs. That's why you have a fuel pump. The fuel pump is a low pressure pump and only pumps when needed. When you first turn your key on, can you hear the pump clicking. Also, you said you ran out of gas, did you look in tank, while moving bike side to side, to see if there was still gas in there?

It may just be cold outside,. Or perhaps it's been swimming.

Everyone's tank is different, just because your tank is a little smaller, doesn't mean you can't have fun with it.

Have you tried watching motorcycle racing, or tried thinking about riding two bikes at once ?

Your tank looks like it's supposed to from your photo. The gas tanks are made with a fuel reserve, and when your bike has "run out of gas" you need to switch on the reserve and burn through that before you literally "run out of gas". The amount left when you run out of gas is about 1 gallon of reserve fuel, so even if you're talking about how much you top off your reserve fuel, that should be about a 3.5 gallon volume, so you're about 2 gallons short somehow.

Lastly, Note that if you're filling the bike on the side stand it will fill up faster with less volume than if it's centered.
