Yamaha MT-03 - Owner's Manual > Fuel

1. Fuel tank filler tube
2. Fuel level

Make sure that there is sufficient fuel in the tank. Fill the fuel tank to the bottom of the filler tube as shown.

WARNING

• Do not overfill the fuel tank, otherwise it may overflow when the fuel warms up and expands.
• Avoid spilling fuel on the hot engine.

CAUTION: Immediately wipe off spilled fuel with a clean, dry, soft cloth, since fuel may deteriorate painted surfaces or plastic parts.

Recommended fuel: PREMIUM UNLEADED GASOLINE ONLY

Fuel tank capacity: 15.0 L (3.96 US gal) (3.29 Imp.gal)

Fuel reserve amount (when the fuel level warning light comes on): 4.25 L (1.12 US gal) (0.93 Imp.gal)

CAUTION: Use only unleaded gasoline. The use of leaded gasoline will cause severe damage to internal engine parts, such as the valves and piston rings, as well as to the exhaust system.

Your Yamaha engine has been designed to use premium unleaded gasoline with a research octane number of 95 or higher. If knocking (or pinging) occurs, use a gasoline of a different brand. Use of unleaded fuel will extend spark plug life and reduce maintenance costs.

Fuel tank breather/overflow hose

1. Fuel tank breather/overflow hose
2. Clamp

Before operating the motorcycle:

• Check the fuel tank breather/ overflow hose connection.
• Check the fuel tank breather/ overflow hose for cracks or damage, and replace it if damaged.
• Make sure that the end of the fuel tank breather/overflow hose is not blocked, and clean it if necessary.
• Make sure that the end of the fuel tank breather/overflow hose is positioned inside of the clamp.

Catalytic converter

This model is equipped with a catalytic converter in the exhaust system.

WARNING The exhaust system is hot after operation.

Make sure that the exhaust system has cooled down before doing any maintenance work.

CAUTION: The following precautions must be observed to prevent a fire hazard or other damages.

• Use only unleaded gasoline.
  The use of leaded gasoline will cause unrepairable damage to the catalytic converter.
• Never park the vehicle near possible fire hazards such as grass or other materials that easily burn.
• Do not allow the engine to idle too long.
