1.OPERATING INSTRUCTIONSFUELBASIC OPERATIONFuel tank capacity: 2.0 US gal (7.4 liter, 1.6 lmp gal)Starting The EngineTo open the fuel fill cap, pull the breather tube out of thesteering stem nut. Then turn the fuel fill capcounterclockwise. Use automobile gasoline with a pump octane number of 92 or higher. If “knocking” or “pinging” occurs, try a different brand of gasoline or a higheroctane grade.WARNING Gasoline is extremely flammable and is explosive under certain conditions. Perform this operation in a well-ventilated area with the enginestopped. Do not smoke or allow flames or sparks inthe area where gasoline is drained or stored andwhere the fuel tank is refueled.(1) FUEL FILL CAP2(2) BREATHER TUBEONOFFWARNING 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 transmission in gear and clutch engaged may result in injury or damage.NOTE: This motorcycle can be kickstarted with the transmission in gear by disengaging the clutch beforeoperating the kickstarter.(1) FUEL VALVECheck the engine oil, transmission oil and coolant levels before starting the engine (page 21, 23, 24).Warm Engine Starting: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 thechoke knob fully out.4. If the temperature is below 0 C (32 F), open thethrottle two or three times. (The engine requires aricher mixture for starting in cold weather. Whenthe throttle is so opened, the accelerator pump willfeed extra fuel to the cylinder, thereby facilitatingstarting in cold weather.)5. With the throttle closed, operate the kickstarter starting from the top of the kickstarter stroke, kick throughto the bottom with a rapid, continuous motion.(Do not open the throttle, As the carburetor isequipped with an accelerator pump, excessive fuelwill be charged into the engine, and the spark plugwill be fouled if the throttle is opened and closedrepeatedly. Excessive fuel in the engine makes kickstarting difficult.)6. About a minute after the engine starts, push thechoke knob back all the way to fully OFF.If idling is unstable, open the throttle slightly.(2) CHOKE KNOB1. Turn the fuel valve ON.2. Shift the transmission into neutral.3. Pull the hot start lever and kick-start the engine. (Donot open the throttle.)4. As soon as the engine starts, release the hot startlever.1(1) HOT START LEVER

Starting the engine after a stall during riding or after afall:1. Shift the transmission into neutral.2. Pull the hot start lever and kick-start the engine. (Donot open the throttle.)3. As soon as the engine starts, release the hot startlever.Starting the engine excessively charged with fuel bythrottle blipping or other reasons:Stopping The Engine1. Shift the transmission into neutral.2. Turn the fuel valve OFF.3. Lightly open the throttle 2 – 3 times, and then closeit.4. Depress and hold the engine stop button until theengine stops completely.NOTE: Failure to close the fuel valve may cause the carburetor to overflow.1. Shift the transmission into neutral.2. With the throttle fully opened, repeat kickstarter operation approximately 10 times very slowly to discharge excessive fuel from the engine.3. Pull the hot start lever and kick-start the engine (Donot open the throttle.)4. As soon as the engine starts, release the hot startlever.(1) THROTTLE GRIPBreak-In ProcedureHelp 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 rapidacceleration.This same procedure should be followed each timewhen: Piston is replaced Rings are replaced Cylinder is replaced Crankshaft or crank bearing are replaced(2) ENGINE STOP BUTTON3

1. OPERATING INSTRUCTIONSADJUSTMENT FOR PERSONAL FITControl Positioning Position the control levers so that control use iscomfortable when both seated and standing. Adjust control lever mounting bolt torque so thatthe levers will rotate on the handlebar in a fall,rather than bending or breaking. Apply HondaThread Lock or an equivalent to the threads of thesebolts prior to adjustment to help ensure the correcttorque is retained. Tighten the top bolts first.Handlebar Position, Width & Shape Position the handlebar so that both gripping the barand operating the controls are comfortable whileboth seated and standing, while riding straightahead and turning. Tighten the forward bolts first. The handlebar position may be moved rearwardeither 3 mm (using optional handlebar lower holders) or 6 mm (by rotating the standard holders 180degrees). Refer to the Service Manual for installation instructions. Be sure to check the control cableand wiring harness routing after adjustment. Handlebar width can be trimmed with a hacksaw tobetter suit your particular shouIder width and ridingpreference. Think this through carefully and cut offjust a small amount at a time from both sides equally.It is obviously much easier to make the handlebarnarrower than it is to add material.11(1) CONTROL LEVER MOUNT BOLTS Position the shifter and brake pedal so that they areclose to your boot for rapid access, but not so closethat either is depressed when sitting or standingcomfortably on the bike.8NOTE: Chamfer the edges to remove burrs and otherirregularities or roughness after sawing the handlebar. An alternate handlebar shape, through varying riseor rearward sweep dimensions, will provide furtheradjustment to riding position and may better suityour particular body size or riding style. Each of theergonomic dimensions of the machine were determined to suit the greatest possible number of riders based on an average size rider.Additional Individualized Adjustments Initial suspension adjustments should be performedafter a minimum of two hours of easy break-in time.Complete information on suspension adjustment isgiven in the Suspension Adjustment section. Optional front and rear suspension springs (front:stiffer and softer, rear: stiffer and softer) are available to tailor your CRF specifically for your weight,riding style and course conditions. Follow the instructions given in the rear suspension sag settingsection of Suspension Adjustment to determine ifyour combined rider and sprung machine weight(rider fuIIy dressed for competition and machinecoolant, oil and fuel levels ready for competition)requires an optional stiffer or softer rear spring. Theuse of the stiffer rear spring may need to be balanced by the use of the stiffer front spring. In order to further fine tune your CRF for specificcourse terrain and conditions, there is a choice ofboth higher and lower final drive ratios with twooptional aluminum driven sprockets. For muddy orsandy courses, there is a more durable steel drivensprocket with the standard number of teeth. Like theoptional springs, these sprockets are listed in theoptional parts section of this manual.
