2002 Harley-David Ultra Classic sputters at 1/2 tank gas.
What would cause my 2002 Harley-Davidson Ultra Classic to start sputtering and throttle body backfiring after using 1/2 of a full tank of fuel? I refuel to full and it runs fine.

Ruling out water contamination (water settles and heavier than gasoline), is it possible for restriction in the fuel line and/or shutoff valve (if they're still used)? Ethanol blends attract moisture and can cause premature corrosion in fuel lines and metals. Fuel may also corrode carburetor parts.
