NOTICE

Do not spill fuel onto the motorcycle while refueling. Immediately wipe up fuel spills on your motorcycle. Fuel can cause damage to cosmetic surfaces. (00147b)

NOTICE

Use only unleaded fuel in catalytic converter-equipped motorcycles. Using leaded fuel will damage the emission control system. (00150c)

WARNING

Do not store motorcycle with gasoline in tank within the home or garage where open flames, pilot lights, sparks or electric motors are present. Gasoline is extremely flammable and highly explosive, which could result in death or serious injury. (00003a)

WARNING

Avoid spills. Slowly open fuel filler cap. Do not fill above bottom of filler neck insert, leaving air space for fuel expansion. Secure filler cap after refueling. Gasoline is extremely flammable and highly explosive, which could result in death or serious injury. (00028b)

WARNING

Do not use aftermarket fuel caps. Aftermarket fuel caps may fit improperly and leak, which could lead to death or serious injury. See a Harley-Davidson dealer for approved fuel caps. (00034a)

NOTE

Extended exposure of fuel filler cap to rain/washing may cause a small amount of water to collect between the pop-up cap and the threaded body. Simply remove the fuel cap and tilt to drain water. Water cannot flow through the fuel filler cap.

Removing Fuel Filler Cap

See Figure 1 and Figure 2. To remove fuel filler cap, press down on cap and rotate 1/8 turn counterclockwise. Cap will popup and may be unscrewed with counterclockwise rotation.

Installing Fuel Filler Cap

Screw fuel filler cap clockwise into fuel tank threads firmly. Press down on cap and rotate cap 1/8 turn clockwise to lock cap in down position.

NOTE

There is no ratchet in this fuel cap, so it will not click when you have installed and tightened the cap.

LED Fuel Gauge

See Figure 1 and Figure 3. The fuel gauge has seven red LEDs which indicate the amount of fuel in the tank. Refer to Table 1.

NOTE

The fuel gauge is mirror glass. Recommended cleaning is with glass cleaner. Any type of abrasive chrome cleaner could damage the surface and damage surrounding painted surfaces.
The fuel gauge is equipped with a light-sensitive sensor. The sensor causes the fuel gauge to illuminate brighter in lighted conditions.
When the fuel tank has less than 3.8 L (1.0 USgal) of fuel remaining, the low fuel lamp lights in the speedometer.
The gas pump icon on the LED fuel gauge is not a low fuel warning lamp. It will be illuminated at all times when the ignition/headlamp key switch is in the IGNITION position.
