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.
