That's why we urge you to read this message before you let any young person ride this motorcycle. Off-road riding can be fun. But as with riding a bicycle, bad judgements can result in injuries, and we don't want that to happen ! As a parent, you can help prevent accidents by making good decisions about if, when, and how your youngster rides this motorcycle. Riding Readiness The first decision you'll need to make is whether your youngster is ready to ride. Riding readiness varies widely from one person to another, and age and size are not the only factors. PHYSICAL ABILITY is an important consideration. For example, riders must be big enough to hold the motorcycle up, get on, and comfortably sit on the seat with both feet touching the ground. They should also be able to easily reach and work the brakes, the throttle and all other controls. ATHLETIC ABILITY is necessary for riding a motorcycle. Generally speaking, your youngster should be good at riding a bicycle before getting on a motorcycle. Can your youngster judge speeds and distances on a bicycle and react with proper hand and foot actions ? Anyone who does not have good coordination,balance, and agility is not ready to ride this motorcycle. MENTAL AND EMOTIONAL MATURITY are requirements for safe riding. Does your youngster think through problems and come to logical solutions? On a bicycle, does your youngster obey safe riding rules ? Be honest! Young people who take unnecessary risks, make bad judgements and don't obey rules are not ready to ride this motorcycle. Instruction and Supervision If you decide that your youngster is ready to safely operate this motorcycle, make sure both of you carefully read and understand the Owner's Manual before riding. Also be sure that your youngster has a helmet and other appropriate riding equipment and always wears it when operating the vehicle or sitting on it. GOOD INSTRUCTION is an important part of hands-on training. The teacher can either be you or another responsible adult who has experience with off-road motorcycle riding. (For help in finding a qualified instructor, talk with your Honda dealer.) Even if you're not the main teacher, it's up to you to ensure your youngster's safety. Remember, learning to ride a motorcycle is a gradual step-by-step process. It takes time, patience and practice — many hours over a period of weeks or months. SUPERVISION is another important obligation of parents. Even after youngsters have become skilled off-road riders, they should always ride with adult supervision. It helps to regularly remind young riders of basic safety rules and cautions. And remember, it's your responsibility to see that the vehicle is properly maintained and kept in safe operating condition. SAFE AND RESPONSIBLE RIDING must be an ongoing commitment—by you and your youngster. When you both put safety first, you can enjoy more peace of mind, and your youngster can enjoy more hours of safe off-road riding. For your convenience, this CRF70F comes with an ignition switch and key. Remove the key when the motorcycle is parked to help prevent unauthorized use. IMPORTANT SAFETY INFORMATION Your motorcycle can provide many years of service and pleasure—if you take responsibility for your own safety and understand the challenges you can meet while riding. This motorcycle has been designed for younger riders, as well as for smaller adults. However, not all youngsters are physically or emotionally ready to ride. Therefore, before parents allow any youngster to ride this motorcycle, we urge them to carefully read the Important Message to Parents on page 1. There is much that you can do to protect yourself when you ride. You'll find many helpful recommendations throughout this manual. Following are a few that we consider most important. Always Wear a Helmet It's a proven fact: helmets significantly reduce the number and severity of head injuries. So always wear an approved motorcycle helmet. We also recommend that you wear eye protection, sturdy boots, gloves and other protective gear (page 5). Never Carry a Passenger Your motorcycle is designed for one person only. There are no handholds, footrests, or seat for a second person—so never carry a passenger. A passenger could interfere with your ability to move around to maintain your balance and control of the motorcycle. Ride Off-Road Only Your motorcycle is designed and manufactured for offroad use only. The tyres are not made for pavement, and the motorcycle does not have turn signals and other features required for use on public roads. If you need to cross a paved or public road, get off and walk your motorcycle across. Take Time to Learn and Practice Developing off-road riding skills is a gradual, step-by-step process. Start by practicing at low speeds in a safe area and slowly build your skills. Personal instruction from an experienced rider can also be valuable. If you need assistance, ask your dealer about riding groups in your area. Be Alert for Off-Road Hazards The terrain can present a variety of challenges when you ride off-road. Continually “read” the terrain for unexpected turns, drop-offs, rocks, ruts, and other hazards. Always keep your speed low enough to allow time to see and react to hazards. Ride Within Your Limits Pushing the limits is another major cause of motorcycle accidents. Never ride beyond your personal abilities or faster than conditions warrant. Remember that alcohol, drugs, fatigue and inattention can significantly reduce your ability to make good judgements and ride safely. Don’t Drink and Ride Alcohol and riding don’t mix. Even one drink can reduce your ability to respond to changing conditions, and your reaction time gets worse with every additional drink. So dont drink and ride, and dont let your friends drink and ride either. Keep Your Bike in Safe Condition For safe riding, it's important to inspect your motorcycle before every ride and perform all recommended maintenance. Never exceed load limits, and only use accessories that have been approved by Honda for this motorcycle. See page 7 for more details. Others * This motorcycle is not equipped with lights. Don't ride at night. PROTECTIVE APPAREL For your safety, we strongly recommend that you always wear an approved motorcycle helmet, eye protection, boots, gloves, long pants, and a long-sleeved jersey, shirt or jacket whenever you ride. Although complete protection is not possible, wearing proper gear can reduce the chance of injury when you ride. Following are suggestions to help you choose proper gear. | Not wearing a helmet increases the chance of serious injury or death in a crash. Be sure you always wear a helmet, eye protection and other protective apparel when you ride. Helmets and Eye Protection Your helmet is your most important piece of riding gear because it offers the best protection against head injuries. A helmet should fit your head comfortably and have a chin strap that can be tightened securely. An open-face helmet offers some protection, but a full-face helmet offers more. Always wear a face shield or goggles to protect your eyes and help your vision. Additional Riding Gear In addition to a helmet and eye protection, we also recommend: e Sturdy off-road motorcycle boots to help protect your feet, ankles, and lower legs. e Off-road motorcycle gloves to help protect your hands. e Riding pants with knee and hip pads, a riding jersey with padded elbows, and a chest/shoulder protector. LOAD LIMITS AND GUIDELINES Your Honda was designed as a rider-only motorcycle. It was not designed to carry a passenger or cargo. A passenger or cargo could interfere with your ability to move around to maintain your balance and control of the motorcycle. In addition, exceeding the weight limits or carrying an unbalanced load can seriously affect your motorcycle’s handling, braking, and stability. Adding accessories or making modifications that change this motorcycle’s design and performance can also make it unsafe. Also, the weight of any accessories will reduce the maximum load the motorcycle can carry. The following pages give more specific information on loading, accessories and modifications. Loading How much weight you put on your motorcycle, and how you load it, are important to your safety. If you decide to carry cargo, you should be aware of the following information. Overloading or carrying a passenger can cause a crash and you can be seriously hurt or killed. Follow all load limits and other loading guidelines in this manual. Load Limits Following are the load limits for your motorcycle: Maximum weight capacity: 60 kg (132 Ibs) Includes the weight of the rider and any accessories Loading Guidelines As discussed on page 7, we recommend that you do not carry any cargo on this motorcycle. However, if you decide to carry cargo, ride at reduced speeds and follow these common-sense guidelines: e Keep cargo small and light. Make sure it cannot easily be caught on brush or other objects, and that it does not interfere with your ability to shift position to maintain balance and stability. e Place weight as close to the center of the motorcycle as possible. e Do not attach large or heavy items (such as a sleeping bag or tent) to the handlebar, fork, or front fender. e Make sure that all cargo is tied down securely. e Never exceed the maximum weight limit. eCheck that both tyres are properly inflated (page 25). Accessories and Modifications Modifying your motorcycle or using non- Honda accessories can make your motorcycle unsafe. Before you consider making any modifications or adding an accessory, be sure to read the following information. Improper accessories or modifications can cause a crash in which you can be seriously hurt or killed. Follow all instructions in this owner's manual regarding accessories and modifications. Accessories We strongly recommend that you use only genuine Honda accessories that have been specifically designed and tested for your motorcycle. Because Honda cannot test all other accessories, you must be personally responsible for proper selection, installation and use of non-Honda accessories. Check with your dealer for assistance and always follow these guidelines: * Make sure the accessory does not reduce ground clearance and lean angle, limit suspension travel or steering travel, alter your riding position or interfere with operating any controls. Modifications We strongly advise you not to remove any original equipment or modify your motorcycle in any way that would change its design or operation. Such changes could seriously impair your motorcycle’s handling, stability and braking, making it unsafe to ride. Removing or modifying your exhaust system (such as the spark arresters or mufflers) or other equipment can also make your motorcycle illegal. 10 PARTS LOCATION Front brake lever \ Throttle grip Engine stop switch Fuel fill cap 11 Oil filler cap/dipstick Ignition switch Kickstarter Foot peg Rear brake pedal 12 Choke lever Shift lever Fuel valve Side stand Foot peg 13 MAJOR COMPONENTS (Information you need to operate this motorcycle) BRAKES Front Brake Brakes are items of personal safety and should always be maintained in proper adjustment. The distance the front brake lever or rear brake pedal moves before the brake starts to engage is called freeplay. Measured at the tip of the front brake lever (1), freeplay should be maintained at: 20—30 тит (0.8—1.2 in) Adjust the freeplay of the brake lever with the front wheel pointed straight ahead. Adjustment: ack the rubber dust cover (2). Loosen the lock nut (3) and turn the adjuster (4).

OFF With the fuel valve in the OFF position, fuel cannot flow from the tank to the carburetor. Turn the valve OFF whenever the motorcycle is not in use. ON With the fuel valve in the ON position, fuel will flow from the main fuel supply to the carburetor. RES With the fuel valve in the RES position, fuel will flow from the reserve fuel supply to the carburetor. Use the reserve fuel only when the main supply is gone. Refill the tank as soon as possible after switching to RES. The reserve fuel supply is: 0.7 0 (0.18 US gal , 0.15 Imp gal) 20 Remember to check that the fuel valve is in the ON position each time you refuel. If the valve is left in the RES position, you may run out of fuel with no reserve. OFF (1) (1) Fuel valve Fuel Tank The fuel tank capacity including the reserve supply is; 5.0 2 (1.32 US gal , 1.10 Imp gal) To open the fuel fill cap (1), pull the breather tube (2) from the front number plate (3). Turn the fuel fill cap counterclockwise, Do not overfill the tank. There should be no fuel in the filler neck (4). After refueling, be sure to tighten the fuel fill cap firmly by turning it clockwise. Insert the breather tube into the front number plate. A WARNING Petrol is highly flammable and explosive. You can be burned or seriously injured when handling fuel. e Stop the engine and keep heat, sparks, and flame away. e Refuel only outdoors. * Wipe up spills immediately. (2) (1) Fuel fill cap (3) Front number plate (2) Breather tube (4) Filler neck 21 Use unleaded or low-lead petrol with a research octane number of 91 or higher. We recommend that you use unleaded petrol because it produces fewer engine and spark plug deposits and extends the life of exhaust system components. 22 If “spark knock” or “pinking” occurs at a steady engine speed under normal load, change brands of petrol. If spark knock or pinking persists, consult your Honda dealer. Failure to do so is considered misuse, and damage caused by misuse is not covered by Honda's Limited Warranty. Occasionally you may experience light spark knock while operating under heavy loads. This is no cause for concern, it simply means your engine is operating efficiently. Petrol Containing Alcohol If you decide to use a petrol containing alcohol (gasohol), be sure it’s octane rating is at least as high as that recommended by Honda. There are two types of “gasohol”: one containing ethanol, and the other containing methanol. Do not use petrol that contains more than 10 % ethanol. Do not use petrol containing methanol (methyl or wood alcohol) that does not also contain cosolvents and corrosion inhibitors for methanol. Never use petrol containing more than 5 % methanol, even if it has cosolvents and corrosion inhibitors. Fuel system damage or engine performance problems resulting from the use of fuels that contain alcohol is not covered under the warranty. Honda cannot endorse the use of fuels containing methanol since evidence of their suitability is as yet incomplete. Before buying fuel from an unfamiliar station, try to find out if the fuel contains alcohol. If it does, confirm the type and percentage of alcohol used. If you notice any undesirable operating symptoms while using a petrol that contains alcohol, or one that you think contains alcohol, switch to a petrol that you know does not contain alcohol. 23 ENGINE OIL Engine Oil Level Check Check the engine oil level each day before operating the motorcycle. The oil filler cap/dipstick (1) is at the rear of the right crankcase cover and contains a dipstick for measuring the oil level. Oil level must be maintained between the upper (2) and lower (3) level marks on the oil filler cap/ dipstick. 1. Hold the motorcycle upright on firm level ground. 2. Start the engine and let it idle for 3—5 minutes. | 3.Stop the engine. After 2—3 minutes, remove the oil filler cap/dipstick, wipe it clean, and reinsert the oil filler cap/ dipstick without screwing it in. Remove the oil filler cap/dipstick. The oil level should be between the upper and lower level marks on the oil filler cap/dipstick. 4. If required, add the specified oil (see page 56) up to the upper level mark. Do not overfill. 24 5. Reinstall the oil filler cap/dipstick. Check for oil leaks. Running the engine with insufficient oil can cause serious engine damage. (1) Oil filler cap/dipstick (2) Upper level mark (3) Lower level mark TYRES | To safely operate your motorcycle, the tyres must be the proper type (off-road) and size,. in good condition with adequate tread, and correctly inflated. INTENTA Using tyres that. are excessively worn or improperly inflated can cause a crash in which you can be seriously hurt or killed. Follow all instructions in this owner's manual regarding tyre inflation and maintenance. Air Pressure Properly inflated tyres provide the best combination of handling, tread life, and riding comfort. Generally, underinflated tyres wear unevenly, adversely affect handling, and are more likely to fail from being overheated. Underinflated tyres can also cause wheel damage in rocky terrain. Overinflated tyres make your motorcycle ride harshly, are more prone to damage from surface hazards, and wear unevenly. Make sure the valve stem caps are secure. If necessary, install a new cap. 25 Always check air pressure when your tyres are “cold.” If you check air pressure when your tyres are “warm” — even if your motorcycle has only been ridden for a few miles — the readings will be higher. If you let air out of warm tyres to match the recommended cold pressures, the tyres will be underinflated. The recommended “cold” tyre pressures are: Front 100 kPa {1.0 kgf/cm? , 15 psi) Rear 100 kPa {1.0 kgf/cm? , 15 psi) 26 Inspection Whenever you check the tyre pressures, you should also examine the tyre treads and sidewalls for wear, damage, and foreign objects: Look for: ¢ Bumps or bulges in the side of the tyre or the tread. Replace the tyre if you find any bumps or bulges. e Cuts, splits or cracks in the tyre. Replace the tyre if you can see fabric or cord. e Excessive tread wear. Also, if you hit a pothole or hard object, pull to the side of the road as soon as you can safely and carefully inspect the tyres for damage. Tread Wear Replace tyres before tread depth at the center of the tyre reaches the following (1) limit: Minimum tread depth Front: 3.0 mm (0.12 in) Rear: 3.0 mm (0.12 in) (1) Tyre tread depth 27 Tube Repair and Replacement If a tube is punctured or damaged, you should replace it as soon as possible. A tube that is repaired may not have the same reliability as a new one, and it may fail while you are riding. If you need to make a temporary repair by patching a tube or using an aerosol sealant, ride cautiously at reduced speed and have the tube replaced before you ride again. Any time a tube is replaced, the tyre should be carefully inspected as described on page 26 28 Tyre Replacement The tyres that came on your motorcycle were designed to match the performance capabilities of your motorcycle and provide the best combination of handling, braking, durability and comfort. Installing improper tyres on your motorcycle can affect handling and stability. This can cause a crash in which you can be seriously hurt or killed. Always use the size and type of tyres recommended in this owner's manual. The recommended tyres for your motorcycle are: Front: 2.50-14 4PR Rear: 3.00-12 4PR Type: bias-ply, tube Whenever you replace a tyre, use one that is equivalent to the original and be sure the wheel is balanced after the new tyre is installed. Also remember to replace the inner tube whenever you replace a tyre. The old tube will probably be stretched, and if installed in a new tyre, it could fail. 29 ESSENTIAL INDIVIDUAL COMPONENTS IGNITION SWITCH The ignition switch (1) is located below the fuel tank. The ignition switch is used to prevent unauthorized use of the motorcycle. Before riding, insert the key and turn it to the ON position. After parking the motorcycle, remove the key.

If you detect any problem, be sure you take care of it, or have it corrected by your Honda dealer. Improperly maintaining this motorcycie or failing to correct a problem before riding can cause a crash in which you can be seriously hurt or killed. Always perform a pre-ride inspection before every ride and correct any problems. 34 1. Engine oil level—add engine oil if required (page 56). Check for leaks. 2. Fuel level —fill fuel tank when necessary (page 21). Check for leaks. 3. Front and rear brakes—check operation and if necessary, adjust freeplay (pages 14 — 18). 4. Tyres—check condition and pressure (pages 25 — 29). 5. Spokes — check and tighten if necessary (page 74 ). 6. Drive chain — check condition and slack (page 69 ). Adjust and lubricate if necessary. 7. Chain slider — check slider wear (page 70). 8. Throttle — check for smooth opening and full closing in all steering positions. Adjust freeplay if necessary (pages 64 — 65). 9. Spark plug and high tension terminal — check for looseness. 10. Engine stop switch—check for proper function (page 31). 11. Nuts, bolts, fasteners — check the front and rear wheels to see that the axle nuts are tightened securely. Check security of all other nuts, bolts, and fasteners. 35 STARTING THE ENGINE Always follow the proper starting procedure described below. Your motorcycle’s exhaust contains poisonous carbon monoxide gas. High levels of carbon monoxide can collect rapidly in enclosed areas such as a garage. Do not run the engine with the garage door closed. Even with the door open, run the engine only long enough to move your motorcycle out of the garage. 36 Preparation Before starting, insert the key and turn the ignition switch ON. Make sure that the transmission is in neutral. Turn the engine stop switch to O (RUN) and the fuel valve ON. Starting Procedure To restart a warm engine, follow the procedure for “High Air Temperature.” Normal Air Temperature 10° —35°C (50° — 95° F) 1.

Follow steps 1-2 under “Normal Air Temperature”. 2 Warm up the engine by opening and closing the throttle slightly. 3 Continue warming up the engine until it runs smoothly and responds to the throttle, when the choke lever (1) is at Fully OFF (B). 38 Extended use of the choke may impair piston and cylinder wall lubrication and damage the engine. Flooded Engine If the engine fails to start after repeated attempts, it may be flooded with excess fuel. To clear a flooded engine, turn the engine stop switch to $8 (OFF) and push the choke lever down to Fully OFF (B). Open the throttle fully and crank the engine several times with the kickstarter. Turn the engine stop switch to () (RUN) and open the throttle slightly; start the engine using the kickstarter. RUNNING-IN Help assure your motorcycle’s future reliability and performance by paying extra attention to how you ride during the first operating day or 25 km (15 miles). During this period, avoid full-throttle starts and rapid acceleration. 39 RIDING Review Motorcycle Safety (pages 1 —10) before you ride. Make sure the side stand is fully retracted before riding the motorcycle. If the stand is extended, it may interfere with control during a left turn. Make sure you understand the function of the side stand mechanism. (See MAIN- TENANCE SCHEDULE on page 48 and explanation for SIDE STAND on page 81). 1. After the engine has warmed up, the motorcycle is ready for riding. 2. Close the throttle and raise the shift lever to shift into 1st (low) gear. 40 3. Increase engine speed by gradually opening the throttle. 4. When your speed increases, close the throttle and shift to 2nd gear by raising the shift lever. 5. This sequence is repeated to shift to 3rd gear. 6. Raise the pedal to shift to a higher gear and depress the pedal to shift to a lower gear. Each stroke of the pedal engages the next gear in sequence. The pedal automatically returns to the horizontal position when released. „о Shifting pattern * Do not downshift when traveling at a speed that would force the engine to overrev in the next lower gear; the rear wheel may lose traction, resulting in a possible loss of vehicle control. e Do not shift gears without closing the throttle. The engine and drive train could be damaged by overspeed and shock. e Do not tow the motorcycle or coast for long distances while the engine is off. The transmission will not be properly lubricated and damage may result. * Do not run the engine at high rpm with the transmission in neutral. Serious engine damage may result. 41 HIGH ALTITUDE RIDING When operating this motorcycle at high altitude the air-fuel mixture becomes overly rich. Driveability and performance may be reduced and fuel consumption increased. The carburetor can be modified to compensate for this high altitude richness, however it must be returned to standard specifications before extended operation at low altitudes (below 1,200 m, 4,000 feet). See your Honda dealer for this high altitude modification. Sustained operation at lower altitudes with high altitude carburetor modifications may cause engine overheating and damage. 42 BRAKING For normal braking, gradually apply both the front and rear brakes while downshifting to suit your road speed. For maximum deceleration, close the throttle and apply the front and rear brakes firmly. Important Safety Reminders: e Independent operation of only the brake lever or brake pedal reduces stopping performance. e Extreme application of the brake controls may cause wheel lock, reducing control of the motorcycle. * When possible, reduce speed or brake before entering a turn; closing the throttle or braking in mid-turn may cause wheel slip. Wheel slip will reduce control of the motorcycle. * When riding in wet or rainy conditions, or on loose surfaces, the ability to maneuver and stop will be reduced. All of your actions should be smooth under these conditions. Rapid acceleration, braking or turning may cause loss of control. For your safety, exercise extreme caution when braking, accelerating or turning. e When descending a long, steep grade, use engine compression braking by down- shifting, with intermittent use of both brakes. Continuous brake application can overheat the brakes and reduce their effectiveness. PARKING 1. After stopping the motorcycle, shift the transmission into neutral and turn the fuel valve OFF. Turn the engine stop switch 23 (OFF). 2.Use the side stand to support the motorcycle while parked. Park the motorcycle on firm, level ground to prevent it from falling over. H you must park on a slight incline, aim the front of the motorcycle uphill to reduce the possibility of rolling off the side stand or overturning. 3. Turn the ignition switch OFF and remove the key. ANTI-THEFT TIPS 1. Be sure the registration information for your motorcycle is accurate and current. 2. Park your motorcycle in a locked garage whenever possible. 3. Use an additional anti-theft device of good quality. 4. Put your name, address and phone number in this Owner’s Manual and keep it on your motorcycle at all times. Many times stolen motorcycles are identified by information in the Owner's Manuals which are still with them. NAME: ADDRESS: PHONE NO: MAINTENANCE THE IMPORTANCE OF MAINTENANCE A well-maintained motorcycle is essential for safe, economical, and trouble-free riding. It will also help reduce air pollution. Careful pre-ride inspections and good maintenance are especially important because your motorcycle is designed to be ridden over rough off-road terrain. To help you properly care for your motorcycle, this section of the manual provides a Maintenance Schedule. The service intervals in this schedule are based on average riding conditions. More frequent service is needed if you subject your motorcycle to severe use (such as competition) or ride in unusually wet or dusty areas. Frequent servicing of the air cleaner is especially important to help you avoid a possible costly engine repair. If your motorcycle overturns or becomes involved in a crash, be sure your Honda dealer inspects all major parts, even if you are able to make some repairs. I: TCR improperly maintaining this motorcycle or failing to correct a problem before you ride can cause a crash in which you can be seriously hurt or killed. Always follow the inspection and maintenance recommendations and schedules in this owner's manual. 45 MAINTENANCE SAFETY This section includes instructions on some important maintenance tasks. You can perform some of these tasks with the tools provided — if you have basic mechanical skills. Other tasks that are more difficult and require special tools are best performed by professionals. Wheel removal should normally be handled only by a Honda technician or other qualified mechanic; instructions are included in this manual only to assist in emergency service. Some of the most important safety precautions follow. However, we cannot warn you of every conceivable hazard that can arise in performing maintenance. Only you can decide whether or not you should perform a given task. 46 Failure to properly follow maintenance instructions and precautions can cause you to be seriously hurt or killed. Always follow the procedures and precautions in this owner's manual. SAFETY PRECAUTIONS e Make sure the engine is off before you begin any maintenance or repairs. This will help eliminate several potential hazards: + Carbon monoxide poisoning from engine exhaust. Be sure there is adequate ventilation whenever you operate the engine. * Burns from hot parts. Let the engine and exhaust system cool before touching. * Injury from moving parts. Do not run the engine unless instructed to do so. e Read the instructions before you begin, and make sure you have the tools and skills required. * To help prevent the motorcycle from falling over, park it on a firm, level surface, using the side stand or a maintenance stand to provide support. e To reduce the possibility of a fire or explosion, be careful when working around petrol. Use only nonflammable solvent, not petrol, to clean parts. Keep cigarettes, sparks and flames away from all fuel-related parts. Remember that your Honda dealer knows your motorcycle best and is fully equipped to maintain and repair it. To ensure the best quality and reliability, use only new genuine Honda parts or their equivalents for repair and replacement. 47 MAINTENANCE SCHEDULE Perform the Pre-ride Inspection {page 34 ) at each scheduled maintenance period. I: INSPECT AND CLEAN, ADJUST, LUBRICATE OR REPLACE IF NECESSARY C: CLEAN R:REPLACE A:ADJUST L: LUBRICATE The following Maintenance Schedule specifies all maintenance required to keep your motorcycle in peak operating condition. Maintenance work should be performed in accordance with standards and specifications of Honda by properly trained and equipped technicians. Your Honda dealer meets all of these requirements. * Should be serviced by your Honda dealer, unless the owner has proper tools and service data and is mechanically qualified. Refer to the Official Honda Shop Manual. ** In the interest of safety, we recommend these items be serviced only by your Honda dealer. Honda recommends that your Honda dealer should road test your motorcycle after each periodic maintenance is carried out.

Change the engine oil as specified in the maintenance schedule (page 49 ). When running in very dusty conditions, oil changes should be performed more frequently than specified in the maintenance schedule. Please dispose of used engine oil in a manner that is compatible with the environment. We suggest you take it in a sealed container to your local recycling center or service station for reclamation. Do not throw it in the trash or pour it on the ground or down a drain. Used engine oil may cause skin cancer if repeatedly left in contact with the skin for prolonged periods. Although this is unlikely unless you handle used oil on a daily basis, it is still advisable to thoroughly wash your hands with soap and water as soon as possi- ble after handling used oil. If a torque wrench is not used for this installation, see your Honda dealer as soon as possible to verify proper assembly. Change the engine oil with the engine at normal operating temperature and the motorcycle on its side stand to assure complete and rapid draining. | 59 1. Remove the oil filler cap/dipstick (1) from the right crankcase cover. 2. Place a drain pan under the crankcase and remove the oil drain bolt (2). 3. Operate the kickstarter several times while turned the engine stop switch at 52 (OFF) to drain any oil which may be left in the engine. 4. Check that the sealing washer (3) on the drain bolt is in good condition and install the bolt. Replace the sealing washer every other time the oil is changed, or each time if necessary. Oil Drain Bolt Torque: 25 N-m (2.5 kgf-m , 18 Ibf-ft) 5. Fill the crankcase with the recommended grade oil; approximately: 0.6 2 (0.6 US qt, 0.5 Imp at) 60 6.

Recommended plugs: Standard: CR6HSA (NGK) or U20FSR-U (DENSO) For cold climate: (Below 5°C, 41°F) CR5HSA (NGK) or U16FSR-U (DENSO) For extended high speed riding: CR7HSA (NGK) or U22FSR-U (DENSO) For most riding conditions this spark plug heat range number is satisfactory. However, if the motorcycle is going to be operated for extended periods at high speeds or near maximum power in hot climates, the spark plug should be changed to a colder heat range (a higher number). Never use a spark plug with an improper heat range. Severe engine damage could result. 1. Disconnect the spark plug cap. 2. pican any dirt from around the spark plug ase. 3. Remove the spark plug. 4. Visually inspect the spark plug electrodes for wear. The center electrode should have square edges and the side electrode should not be eroded. 5. Discard the spark plug if there is apparent wear or if the insulator is cracked or chipped. 61 6. Check the spark plug gap ( 1) using a wire-type feeler gauge. If adjustment is necessary, bend the side electrode (2) carefully. The gap should be: 0.6—0.7 mm (0.02— 0.03 in) (2) (1) (1) Spark plug gap (2) Side electrode 62 7. Make sure the plug washer is in good condition. 8. With the plug washer attached, thread the spark plug in by hand to prevent cross-threading. 9. Tighten the spark plug: e If the old plug is good: 1/8 turn after it seats. e If installing a new plug, tighten it twice to prevent loosening: a) First, tighten the plug: NGK: 1 turnafter it seats. DENSO: 3/4 turn after it seats. b) Then loosen the plug. c) Next, tighten the plug again: 1/8 turn after it seats. An improperly tightened spark plug can damage the engine. If a plug is too loose, a piston may be damaged. If a plug is too tight, the threads may be damaged. 10. Reinstall the spark plug cap. Take care to avoid pinching any cables or wires. IDLE SPEED Refer to the Safety Precautions on page 47 . Idle Speed: The engine must be at normal operating temperature for accurate idle speed adjustment. 10 minutes of stop-and-go riding is sufficient. Do not attempt to compensate for faults in other systems by adjusting idle speed. See your Honda dealer for regularly scheduled carburetor adjustments. (A) Decrease (B) Increase (1) Throttle stop screw (2) Air screw 1. Warm up the engine and hold the motorcycle upright. 2. Connect a tachometer to the engine. 3. Adjust idle speed with the throttle stop screw (1). Idle speed (In neutral): 1,700 — 100 min” (rpm) Idle Mixture: 1. Adjust the fuel mixture by turning the air screw (2) clockwise until you hear the engine miss or decrease in speed, then counterclockwise until the engine again misses or decreases in speed. Set the air screw exactly between these two extreme positions. | From a fully closed position, the correct setting (between extremes of rich and lean) will be approximately: 1—1/2 2. If the idle speed changes after adjusting fuel mixture, readjust the idle speed by turning the throttle stop screw. 63 THROTTLE OPERATION Refer to the Safety Precautions on page 47 . Cable Inspection: 1. Check for smooth rotation of the throttle grip from the fully open to the fully closed position at both full steering positions. 2. Inspect the condition of the throttle cable (1) from the throttle grip down to the carburetor. If the cable is kinked, chafed or improperly routed, it should be replaced and/or rerouted. 3. Lubricate the cable with a commercially available cable lubricant to prevent premature wear and corrosion. 64 (1) Throttle cable Freeplay Adjustment; 1. Adjust freeplay with the throttle cable adjuster (1). Measured in grip rotation, the standard throttle grip freeplay is: 2.0—6.0 mm (0.08—0.24 in) 2. To adjust the freeplay, loosen the lock nut (2) and turn the adjuster. 3. After adjustment, check again for smooth rotation of the throttle grip from the fully closed to the fully open position with the steering to the full right and left as well as straight ahead. If proper throttle freeplay cannot achieved, contact your Honda dealer.

Excessive valve clearance will cause noise and eventual engine damage. Little or no clearance will prevent the valve from closing and cause valve damage and power loss. Check valve clearance when the engine is cold at the specified intervals. (2) (1) T mark 66 (2) Index mark The checking or adjusting of the clearance should be performed while the engine is cold. The clearance will change as the engine temperature rises. 1. Remove the left crankcase cover. 2. Remove the adjusting hole caps. 3. Rotate the flywheel counterclockwise until the T mark (1) on the flywheel lines up with the index mark (2) on the crankcase. In this position, the piston may either be on the compression or exhaust stroke. The adjustment must be made when the piston is at the top of the compression stroke when both the intake and exhaust valves are closed. This condition can be determined by moving the rocker arms. If they are free, it is an indication that the valves are closed and that the piston is on the compression stroke. If they are tight and the valves are open, rotate the flywheel 360° and realign the T mark to the index mark. 4. Check the clearance of both valves by inserting a feeler gauge (3) between the adjusting screw (4) and the valve stem. Clearance should be: (3) 0.05 mm (0.002 in) | If it is necessary to make an adjustment, loosen the adjusting screw lock nut (5) and turn the adjusting screw so there is a slight resistance when the feeler gauge is inserted. After completing the adjustment, tighten the adjusting screw lock nut while holding the adjusting screw to prevent it from turning. Finally, recheck the clearance to make sure that the adjustment has not been disturbed. (5) (3) Feeler gauge (4) Adjusting screw (5) Adjusting screw lock nut 67 SPARK ARRESTER 1.

The service life of the drive chain is dependent upon proper lubrication and adjustment. Poor maintenance can cause premature wear or damage to the drive chain and sprockets. The drive chain should be checked and lubricated as part of the Pre-ride Inspection (page 34 ). Under severe usage, or when the motorcycle is ridden in unusually dusty or muddy areas, more frequent maintenance will be necessary. Inspection: I. Turn the engine off, place the motorcycle on its side stand and shift the transmission into neutral. 2. Check slack in the lower drive chain run midway between the sprockets. Drive chain slack should be adjusted to allow the following vertical movement by hand: 10—20 тт (0.4— 0.8 тп) 3. Roll the motorcycle forward. Stop. Check the drive chain slack. Repeat this procedure several times. Drive chain slack should remain constant. If the chain is slack only in certain sections, some links are kinked and binding. Binding and kinking can frequently be eliminated by lubrication. Excessive chain slack may allow the drive chain to damage the engine cases. (1) Drive chain 69 4. Check the chain slider (2) for wear. If the ridge (3) in the center of the slider is worn, have your Honda dealer replace the chain slider. (2) Chain slider (3) Ridge 70 5. Measure a section of the drive chain to determine whether the chain is worn beyond its service limit. Remove the drive chain and measure the distance between a span of pins from pin center to pin center. If the distance exceeds the service limit, the chain is worn out and should be replaced. New Chain: 1,080 mm (42.5 in) Service Limit: 1,101 mm (43.3 in) Measure a span of : 85 pins. 6. Inspect the sprocket teeth for possible wear or damage. Damaged sprocket Worn sprocket Teeth Teeth Replace Replace Normal sprocket Teeth GOOD If the drive chain or sprockets are excessively worn or damaged, they should be replaced. Never use a new chain with worn sprockets; rapid chain wear will result. Adjustment: If the drive chain requires adjustment, the procedure is as follows; 1. Place a support block under the engine to raise the rear wheel off the ground. 2. Loosen the rear axle nut (1). (1) Rear axle nut (2) Adjusting nut (3) Adjuster index mark (4) Graduated scale 71 3. Turn the adjusting nut (2) on both the right and left chain adjusters an equal number of turns to increase or decrease chain slack. Align the chain adjuster index marks (3) with the corresponding scale graduations (4) on both sides of the swingarm. If the drive chain slack is excessive when the rear axle is moved to the furthest limit of adjustment, the drive chain is worn and must be replaced. 4. Tighten the axle nut to: 59 N-m (6.0 kgf-m , 43 Ibf-ft) 5. Tighten the adjusting nuts. 6. Recheck drive chain slack. 7. Rear brake pedal freeplay is affected when repositioning the rear wheel to adjust drive chain slack. Check rear brake pedal freeplay and adjust as necessary (page 17 ). 72 If a torque wrench is not used for this installation, see your Honda dealer as soon as possible to verify proper assembly. Lubrication: Use SAE 80 or 90 gear oil or a commercially prepared drive chain lubricants in preference to motor oil or other lubricants. Saturate each chain link joint so that the lubricant penetrates between the link plates, pins, bushings, and rollers. Removal and Cleaning: When the drive chain becomes dirty, it should be removed and cleaned prior to lubrication. 1. With the engine off, carefully remove the master link retaining clip (1) with a pair of pliers. Do not bend or twist the clip. Remove the master link. Remove the drive chain from the motorcycle. 2. Clean the drive chain in high flash-point solvent and allow it to dry. Inspect the drive chain for possible wear or damage. Replace any chain that has damaged rollers, loose fitting links, or otherwise appears unserviceable. Never use petrol or low flash point solvents for cleaning the drive chain. A fire or explosion could result. 3. Inspect the sprocket teeth for possible wear or damage. 4. Lubricate the drive chain (page 72). 5. Pass the chain over the sprockets and join the ends of the chain with the master link. For ease of assembly, hold the chain ends against adjacent rear sprocket teeth while inserting the master link. The master link is the most critical part affecting the security of the drive chain. Master links are reusable, if they remain in excellent condition, but it is recommended that a new master link retaining clip be installed whenever the drive chain is reassembled. Install the master link retaining clip so that the closed end of the clip will face the direction of forward wheel rotation. (1) Retaining clip WHEEL RIMS AND SPOKES Refer to the Safety Precautions on page 47. 1. Inspect the wheel rims (1) and spokes (2) for damage. 2. Tighten any loose spokes. 3. Check wheel rim runout. If runout is noticeable, see your Honda dealer for inspection. Maintenance of spoke tension and wheel trueness are critical to safe motorcycle operation. During the first 150 km (100 miles), spokes will loosen more rapidly due to initial seating of parts. Excessively loose spokes may result in high speed instability and possible loss of control. 74 (1) Wheel rim (2) WHEEL REMOVAL Refer to the Safety Precautions on page 47 . Front Wheel Removal 1.

(1) Side stand spring 81 CLEANING Clean your motorcycle regularly to protect the surface finishes and inspect for damage, wear and oil leakage. Avoid cleaning products that are not specifically designed for motorcycle or automobile surfaces. They may contain harsh detergents or chemical solvents that could damage the metal, paint, and plastic on your motorcycle. If your motorcycle is still warm from recent operation, give the engine and exhaust system time to cool off. We recommend avoiding the use of high pressure water spray (typical in coin- operated car washes). High pressure water (or air) can damage certain parts of the motorcycle. 82 High pressure washer spray can damage certain parts of your motorcycle. If you use a high pressure washer, avoid spraying the following areas: Wheel Hubs Muffler Outlet Under Seat Engine Stop Switch Under Fuel Tank Drive Chain Carburetor Ignition Switch Washing the motorcycle 1. Rinse the motorcycle thoroughly with cool water to remove loose dirt. 2. Clean the motorcycle with a sponge or soft cloth using cool water. Avoid directing water to muffler outlets and electrical parts. 3. Clean the plastic parts using a cloth or sponge dampened with a solution of mild detergent and water. Rub the soiled area gently rinsing it frequently with fresh water. Take care to keep brake fluid or chemical solvents off the motorcycle. They will damage the plastic and painted surfaces. 4. After cleaning, rinse the motorcycle thoroughly with plenty of clean water. Strong detergent residue can corrode alloy parts. 5. Dry the motorcycle, start the engine, and let it run for several minutes. 6. Test the brakes before riding the motorcycle. Several applications may be necessary to restore normal braking - performance. | 7. Lubricate the drive chain immediately after washing and drying the motorcycle. Braking efficiency may be temporarily impaired immediately after washing the motorcycle. Anticipate longer stopping distance to avoid a possible accident. 83 Finishing Touches After washing your motorcycle, consider using a commercially-available spray cleaner/polish or quality liquid or paste wax to finish the job. Use only a non-abrasive polish or wax made specifically for motorcycles or automobiles. Apply the polish or wax according to the instructions on the container. 84 STORAGE GUIDE Extended storage, such as for winter, requires that you take certain steps to reduce the effects of deterioration from non-use of the motorcycle. In addition, necessary repairs should be made BEFORE storing the motorcycle; otherwise, these repairs may be forgotten by the time the motorcycle is removed from storage. STORAGE 1. Change the engine oil. 2. Drain the fuel tank and carburetor into an approved petrol container. Reinstall the fuel fill cap on the tank. To assure proper performance after storage lasting more than one month, it is important to drain the carburetor. AWARNING Petrol is highly flammable and explosive. You can be burned or seriously injured when handling fuel. e Stop the engine and keep heat, sparks, and flame away. e Refuel only outdoors. e Wipe up spills immediately. 85 3. To prevent rusting in the cylinder, perform the following: e Remove the spark plug cap from the spark plug. Using tape or string, secure the cap to any convenient plastic body part so that it is positioned away from the spark plug. e Remove the spark plug from the engine and store it in a safe place. Do not connect the spark plug to the spark plug cap. e Pour a tablespoon (15—20 ст) о? clean engine oil into the cylinder and cover the spark plug hole with a piece of cloth. e Crank the engine several times to distribute the oil. e Reinstall the spark plug and spark plug cap. 86 4.

Frequently Answers and Questions
What are the recommended cold tyre pressures for the CRF 70F?
The recommended cold tyre pressures are: Front 100 kPa (15 psi), Rear 100 kPa (15 psi).
How do I check the engine oil level on the CRF 70F?
Hold the motorcycle upright on firm level ground. Start the engine and let it idle for 3—5 minutes. Stop the engine. After 2—3 minutes, remove the oil filler cap/dipstick, wipe it clean, and reinsert the oil filler cap/dipstick without screwing it in. Remove the oil filler cap/dipstick. The oil level should be between the upper and lower level marks on the oil filler cap/dipstick.
What is the recommended fuel type for the CRF 70F?
Use unleaded or low-lead petrol with a research octane number of 91 or higher. We recommend that you use unleaded petrol because it produces fewer engine and spark plug deposits and extends the life of exhaust system components.
