How far can a Harley go on a tank of gas?

Harley-Davidson motorcycles typically get 40-50 miles per gallon, which is a good reference point for how far you can ride based on the capacity of your gas tank. Sportsters tend to be smaller and get more miles per gallon, while large Touring bikes or Trikes are heavier and are on the lower range of miles per gallon.

What are the parts of fuel system?

Many new bikes are fuel injected, and have a computer to control the amount of gas fed to the engine. There is a fuel pump that provides fuel to the throttle body, which feeds the gasoline to the engine. Older bikes are carbureted, which is a simple system. Gas tends to be gravity fed from a gas tank to the carburetor and the amount of gas delivered to the engine depends on the size of the carburetor jets that are installed. The carburetor is tuned by changing the jets, which have different size orifices, which meters the amount of gasoline delivered to the engine.

Why is my motorcycle leaking gas?

If your motorcycle is leaking gas take a close look to see where the leak is originating. Common problems would include a leaky fuel valve (petcock), damaged fuel line, or if the fuel is coming from the carburetor, a stuck float. A leaky fuel valve or damaged fuel line can be replaced, while a stuck carburetor float can typically be fixed. The carburetor may just need some taps on the float bowl with the handle of a screwdriver to free the stuck float. If that doesn't work, make sure the fuel valve is off, remove the float bowl and check for grit or any debris that could be causing the float needle to not completely seat, which would allow gas to continue flowing into the float bowl even when it is full.
