FUEL Fuel tank capacity: 2.0 US gal (7.4 liter, 1.6 lmp gal) To open the fuel fill cap, pull the breather tube out of thesteering stem nut. Then turn the fuel fill cap ounterclockwise. • Use automobile gasoline with a pump octane number of 92 or higher. If “knocking” or “pinging” oc- curs, try a different brand of gasoline or a higher octane grade. • Gasoline is extremely flammable and is explosive under certain conditions. Perform this operation in a well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the area where gasoline is drained or stored and where the fuel tank is refueled. 1.OPERATING INSTRUCTIONS WARNING BASIC OPERATION Starting The Engine • Never run the engine in an enclosed area. The exhaust contains poisonous carbon monoxide gas thatcan cause loss of consciousness and lead to death. • Attempting to start the engine with the transmis- sion in gear and clutch engaged may result in in- jury or damage. NOTE: • This motorcycle can be kickstarted with the transmission in gear by disengaging the clutch before operating the kickstarter. Check the engine oil, transmission oil and coolant levels before starting the engine (page 21, 23, 24). Cold Engine Starting: 1. Turn the fuel valve ON. 2. Shift the transmission into neutral. 3. If the temperature is 35°C (95°F) or below, pull the choke knob fully out. 4. If the temperature is below 0°C (32°F), open the throttle two or three times. (The engine requires a richer mixture for starting in cold weather. When the throttle is so opened, the accelerator pump will feed extra fuel to the cylinder, thereby facilitating starting in cold weather.) 5. With the throttle closed, operate the kickstarter starting from the top of the kickstarter stroke, kick through to the bottom with a rapid, continuous motion. (Do not open the throttle, As the carburetor is equipped with an accelerator pump, excessive fuel will be charged into the engine, and the spark plug will be fouled if the throttle is opened and closed repeatedly. Excessive fuel in the engine makes kick starting difficult.) 6. About a minute after the engine starts, push the choke knob back all the way to fully OFF. If idling is unstable, open the throttle slightly. (1) FUEL FILL CAP (2) BREATHER TUBE WARNING (1) FUEL VALVE (2) CHOKE KNOB Warm Engine Starting: 1. Turn the fuel valve ON. 2. Shift the transmission into neutral. 3. Pull the hot start lever and kick-start the engine. (Do not open the throttle.) 4. As soon as the engine starts, release the hot start lever.

Always follow the proper starting procedure described below. Your motorcycle can be kickstarted wirh the transmission in gear by pulling in the clutch lever before operating the kickstarter. Preparation Make sure that the transmission is in neutral. Turn the fuel valve ON. Fuel Valve Starting Procedure Always follow the proper starting procedure described as follow. 4. Warm up the engine; don’t operate the throttle. 5. About 15 seconds after the engine startes, push the choke knob back all the way to fully OFF. If idling is unstable, open the throttle slightly. Extended use of the choke may impair piston and cylinder wall lubrication and damage the engine. High Air Temperature 35°C (95°F) or above 1. Do not use the choke. 2. Keep the throttle fully closed. 3. Start the engine following step 3 under Normal Air Temperature. Low Air Temperature 10°C (50°) or below 1. Follow steps 1-4 under Normal Air Temperature. 2. Continue warming up the engine until it runs smoothly and responds to the throttle when the choke knob is pushed back all the way to fully OFF. Extended use of the choke may impair piston and cylinder wall lubrication and damage the engine. Hot Engine Starting 1. Pull the hot start lever (3) and start the engine following step 3 under Normal Air Temperature. 2. As soon as the engine starts, release the hot start lever. NOTICE NOTICE Basic Operating Instructions 15 (1) fuel valve The three-way fuel valve is used to control the flow of fuel from the fuel tank to the carburetor. ON -Turning the fuel valve ON before attempting to start the engine allows fuel to flow from the fuel tank to the carburetor. OFF -Turning the fuel valve OFF after stopping the engine prevents the flow of fuel from the fuel tank to the carburetor. RES -Turning the fuel valve to RES allows fuel to flow from the reserve fuel supply to the carburetor. (1) fuel valve (2) choke knob Check the engine oil, transmission oil and coolant levels before starting the engine (pages 44,47,48). To restart a warm engine, follow the procedure for ”High Air Temperature. ” Normal Air Temperature 10°C-35°C (50°F-95°F) 1. Pull the choke knob (2) up all the way to fully ON, if the engine is cold. 2. Keep the throttle fully closed. 3. Pull the clutch lever all the way in, and press the starter button with the throttle completely closed. Or operate the kickstarter to start the engine. Starting from the top of the stroke, kick through to the bottom with a rapid, continuous motion. Do not operate the throttle. Allowing the kickstarter to snap back freely against the pedal stop can damage the engine case.

(1) THROTTLE GRIP (2) ENGINE STOP BUTTON Break-In Procedure Help assure your CRF’s future reliability and performance by paying extra attention to how you ride during the first operating day or 15 miles (25 km). During this period, avoid full-throttle starts and rapid acceleration. This same procedure should be followed each time when: • Piston is replaced • Rings are replaced • Cylinder is replaced • Crankshaft or crank bearing are replaced
