Frequently Asked Questions - CRF230F (2018) Honda

How do I start the Honda CRF230F engine?

Insert the key and turn the ignition switch ON. Ensure the transmission is in neutral and the fuel valve is ON. For a cold engine (10°-35°C), pull the choke lever fully up, open the throttle slightly, and press the start button. After the engine starts, gradually push the choke lever down to fully OFF. For warm engine, do not use the choke. Do not press the start button for more than 5 seconds at a time.

What type of engine oil should I use and how much?

Use API classification SJ or higher oil that is not labeled as energy conserving, with SAE 10W-30 viscosity and meeting JASO MA standard. Honda recommends Honda '4-STROKE MOTORCYCLE OIL' or equivalent. The oil capacity after draining is approximately 1.0 liter (1.1 US qt).

How do I check and adjust the drive chain slack?

Place the motorcycle on a support block to raise the rear wheel. With the transmission in neutral, check slack in the lower chain run midway between sprockets. The correct vertical movement by hand is 20-30 mm (0.8-1.2 in). To adjust, loosen the rear axle nut and turn both chain adjusters equally. Ensure the same index mark aligns with the stopper pin on both sides. Tighten the axle nut to 108 N·m (80 lbf·ft).

What are the recommended tyre pressures for the CRF230F?

The recommended cold tyre pressures are 100 kPa (1.0 kgf/cm², 15 psi) for both front and rear. Always check when tyres are cold. Underinflated tyres cause poor handling and overheating; overinflated tyres make for a harsh ride and are prone to damage.

How often should the air cleaner be serviced?

According to the maintenance schedule, the air cleaner should be inspected and cleaned every 1,000 km (600 miles) or 6 months, and more frequently when riding in wet or dusty conditions. Use nonflammable solvent for cleaning and saturate with gear oil (SAE 80-90) before reinstalling.

How do I adjust the clutch lever free play?

Normal clutch lever free play is 10-20 mm (0.4-0.8 in). To adjust, use the clutch cable adjuster near the lever: pull back the rubber dust cover, loosen the lock nut, turn the adjuster to achieve the correct free play, then tighten the lock nut. If needed, also adjust the lower end of the cable near the engine.

Can I carry a passenger on the CRF230F?

No, this motorcycle is designed for operator only. The seating configuration does not safely permit carrying a passenger. There are no handholds, footrests, or seat for a second person. Never exceed the maximum weight capacity of 100 kg (220 lb).

What is the fuel valve position for normal and reserve?

The three-way fuel valve has positions: ON (normal operation, main fuel supply), OFF (no fuel flow, use when parked), and RES (reserve fuel supply, about 1.6 liters). Use RES when the main supply runs out, and refill as soon as possible. Remember to turn the valve back to ON after refueling.

How do I replace the headlight bulb?

Turn the ignition switch OFF and allow the bulb to cool. Remove the bolts holding the headlight, then pull back the rubber dust cover. Press the socket slightly and turn it counterclockwise to remove the bulb. Install a new bulb (12V 35W) by aligning the tab with the groove, then reassemble in reverse order.

What maintenance should be performed before each ride?

Perform a pre-ride inspection: check engine oil level, fuel level, brakes (including fluid leaks and free play), tyre condition and pressure, spokes and rim locks, drive chain slack and lubrication, throttle and clutch operation, lights, spark plug and terminal security, engine stop button function, and all nuts/bolts/fasteners. Correct any problems before riding.

MOTORCYCLE SAFETY

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.

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 to be 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 10).

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 off-road 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 crashes. 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 don't drink and ride, and don't let your friends drink and ride either.

Keep Your Bike in Safe Condition

It's important to keep your motorcycle properly maintained and in safe riding condition. Having a breakdown can be difficult, especially if you are stranded off-road far from your base. To help avoid problems, inspect your motorcycle before every ride and perform all recommended maintenance.

Protective Apparel

For your safety, we strongly recommend that you always wear an approved motorcycle helmet, eye protection, boots, gloves, trousers, 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.

WARNING

■ 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:

■ Sturdy off-road motorcycle boots to help protect your feet, ankles, and lower legs.
■ Off-road motorcycle gloves to help protect your hands.
■ Riding trousers 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.

WARNING

■ 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.

(Cont.)

Load Limits

Following are the load limits for your motorcycle:

Maximum weight capacity: 100 kg (220 lb)

Includes the weight of the rider and any accessories. The weight of added accessories will reduce the maximum cargo weight you can carry.

Loading Guidelines

As previously discussed, 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:

• 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.
  ■ Place weight as close to the center of the motorcycle as possible.
  ■ Do not attach large or heavy items (such as a sleeping bag or tent) to the handlebar, fork, or front fender.

■ Make sure that all cargo is tied down securely.
■ Never exceed the maximum weight limit.
■ Check that both tyres are inflated properly (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.

WARNING

■ 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 Honda genuine 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 obscure any lights, reduce ground clearance and banking angle, limit suspension travel or steering travel, alter your riding position, or interfere with operating any controls.
- Be sure electrical equipment does not exceed the motorcycle's electrical system capacity (page 78). A blown fuse can cause a loss of lights or engine power.

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.

PARTS LOCATION

MAJOR COMPONENTS

(Information you need to operate this motorcycle)

Brakes

Front Brake

This motorcycle has a hydraulic front disc brake.

As the brake pads wear, brake fluid level drops.

There are no adjustments to perform, but fluid level and pad wear must be inspected periodically. The system must be inspected frequently to ensure there are no fluid leaks.

If the brake lever free travel becomes excessive and the brake pads are not worn beyond the recommended limit (page 64), there is probably air in the brake system and it must be bled. See your Honda dealer for this service.

Brake fluid level

With the motorcycle in an upright position, check the fluid level. It should be above the lower level mark (1). If the level is at or below the lower level mark, check the brake pads for wear (page 64).

Worn pads should be replaced. If the pads are not worn, have your brake system inspected for leaks.

The recommended brake fluid is Honda DOT 4 from a sealed container.

Do not mix different types of brake fluids, because they are not compatible. (E.g.: DOT 4 with DOT 3).

(1) Lower level mark

Front brake lever

Never use adjusters other than those designed for this motorcycle. Install a new adjuster from the lever side with the lock nut under the head of the adjuster.

1. Pull back the rubber dust cover (1).
2. Loosen the lock nut (2).

(Cont.)

1. To position the front brake lever (3) farther away from the handgrip, turn the adjuster (4) clockwise. To position the front brake lever closer to the handgrip, turn the adjuster counterclockwise.
2. Tighten the lock nut. Return the dust cover to its normal position.
3. Apply the brake, release it, then spin the wheel and check that it rotates freely. Repeat this procedure several times.
4. Check free play by pulling in slowly on the front brake lever until the brake starts to engage.

Free play:

$$ 1 0 - 2 0 \mathrm{mm} (0. 4 - 0. 8 \text { in }) $$

If brake lever free play is not within this range, see your Honda dealer.

Other checks

Check the clutch cable for kinks or signs of wear that could cause sticking or failure.

Lubricate the clutch cable with a commercially available cable lubricant to prevent premature wear and corrosion.

Fuel

Fuel Valve

The three way fuel valve (1) is on the left side below the fuel tank.

ON

With the fuel valve in the ON position, fuel will flow from the main fuel supply to the carburetor.

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.

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:

1.6 liters (0.42 US gal, 0.35 Imp gal)

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.

(1) Fuel valve

Fuel Tank

The fuel tank capacity including the reserve supply is: 7.0 liters (1.85 US gal; 1.54 Imp gal)

To open the fuel fill cap (1), pull out the breather tube (2) from the steering stem nut (3). Then turn the fuel fill cap counterclockwise.

Do not overfill the tank. There should be no fuel in the bottom of 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 steering stem nut.

WARNING

Petrol is highly flammable and explosive. You can be burned or seriously injured when handling fuel.

■ Stop the engine and keep heat, sparks, and flame away.
■ Refuel only outdoors.
■ Wipe up spills immediately.

Use unleaded petrol with a research octane number of 95 or higher.

NOTICE

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.

Engine Oil

Engine Oil Level Check

Check the engine oil level each day before operating the motorcycle.

The oil fill 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 fill 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 fill cap/dipstick, wipe it clean, and reinsert the oil fill cap/dipstick without screwing it in. Remove the oil fill cap/dipstick. The oil level should be between the upper and lower level marks on the oil fill cap/dipstick.

4. If required, add the specified oil (see page 49) up to the upper level mark. Do not overfill.

5. Reinstall the oil fill cap/dipstick. Check for oil leaks.

NOTICE

Running the engine with insufficient oil can cause serious engine damage.

(1) Oil fill 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.

WARNING

■ 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 new caps.

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:

Cold tyre pressures kPa (kgf/cm2; psi)	Front Rear
	100(1.0; 15)	100(1.0; 15)

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.
■ Cuts, splits or cracks in the tyre. Replace the tyre if you can see fabric or cord.
■ Excessive tread wear.

Also, if you hit a pothole or hard object, pull to the side of the road as soon as you safely can and carefully inspect the tyres for damage.

Tread Wear

Replace tyres before tread (1) depth at the center of the tyre reaches the following limit:

Minimum tread depth

Front 3.0 mm (0.12 in)

Rear 3.0 mm (0.12 in)

(1) Tread depth

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.

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.

WARNING

■ 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 80/100-21 51	R NHS
Rear 100/100-18 59	R NHS

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.

Open the throttle fully and press the start button for 5 seconds while pushing the engine stop button. Release the engine stop button and follow the "High Air Temperature" Starting Procedure.

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.

Riding

Review Motorcycle Safety (pages 9 – 13) 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.

1. After the engine has been warmed up, the motorcycle is ready for riding.
2. While the engine is idling, pull in the clutch lever and depress the shift pedal to shift into 1st (low) gear.
3. Slowly release the clutch lever and at the same time gradually increase engine speed by opening the throttle. Coordination of the throttle and clutch lever will assure a smooth positive start.
4. When the motorcycle attains a moderate speed, close the throttle, pull in the clutch lever and shift to 2nd gear by raising the shift pedal.

This sequence is repeated to progressively shift to 3rd, 4th, 5th and 6th (top) gear.

1. Raise the shift pedal to shift to a higher gear and depress the shift pedal to shift to a lower gear. Each stroke of the shift pedal engages the next gear in sequence. The shift pedal automatically returns to the horizontal position when rele

■ 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.
- Do not shift gears without disengaging the clutch and closing the throttle. The engine and drive train could be damaged by overspeed and shock.
- 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 or the clutch lever pulled in. Serious engine damage may result.

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. Pull in the clutch lever before coming to a complete stop to prevent stalling the engine.

Important safety reminders

■ Independent operation of only the brake lever or brake pedal reduces stopping performance.
■ 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.
■ 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. Push the engine stop button in and hold it in until the engine stops completely.
2. Use the side stand to support the motorcycle while parked.

Park the motorcycle on firm, level ground to prevent it from falling over.

If 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.

1. 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.

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.

! WARNING

■ 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.

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.

! WARNING

■ 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

■ 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.

- 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.

■ 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 Genuine Parts or their equivalents for repair and replacement.

Maintenance Schedule

Perform the Pre-ride Inspection (page 31) 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.

Engine Oil

Engine oil quality is the chief factor affecting engine service life. Change the engine oil as specified in the maintenance schedule (page 40).

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 possible after handling used oil.

Changing the oil requires a torque wrench. If you do not have it and the necessary skill, we recommend that you have your Honda dealer perform this service. 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.

1. Remove the oil fill cap/dipstick from the right crankcase cover.

2. Place a drain pan under the crankcase.

3. Remove the oil drain plug (1), O-ring (2), spring (3) and oil strainer screen (4).

4. Clean the oil strainer screen.

5. Check that the oil strainer screen and sealing rubber are in good condition.

6. Replace the O-ring and apply a thin coat of engine oil to the new O-ring before installing it.

7. Install the O-ring to the oil drain plug.

8. Install the oil strainer screen, spring and drain plug.

Drive Chain

(Refer to the Safety Precautions on page 39.)

The service life of the drive chain (1) 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, adjusted and lubricated as part of the Pre-ride (page 31). Under severe usage, or when the motorcycle is ridden in unusually dusty or muddy areas, more frequent maintenance will be necessary.

Inspection

1. Turn the engine off, raise the rear wheel off the ground by placing a support under the engine, 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:

20 - 30 mm (0.8 - 1.2 in)

1. 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.

NOTICE

Excessive chain slack may allow the drive chain to damage the engine cases.

(1) Drive chain

(Cont.)

1. Check the chain slider (2), chain guide slider (3), chain roller (4) and lower slider (5) for wear.

If the chain slider and lower slider are worn to the bottom of the cutouts (6), have your Honda dealer replace the slider. Replace the chain guide slider if the chain is visible through the wear inspection window (7).

Replace the chain roller if it is smaller than:

18 mm (0.7 in)

1. Measure a section of the drive chain to determine whether the chain is worn beyond its service limit. 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: 635 mm (25.0 in)

Service limit: 637 mm (25.1 in)

Span of pins measured: 41

This motorcycle has a staked master link drive chain which requires a special tool for cutting and staking. Do not use an ordinary master link with this chain. See your Honda dealer.

1. Inspect the sprocket teeth for possible wear or damage. Replace if necessary.

Standard sprocket sizes:

Drive sprocket (engine)	Driven sprocket (rear wheel)
13 teeth 50 teeth

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) while holding the rear axle shaft (2).
3. Turn both the right and left chain adjusters (3) equally to increase or decrease chain slack.
4. After adjusting, be sure the same adjuster index marks (4) align with the stopper pins (5) 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.

1. Tighten the rear axle nut to: 108 N.m (11.0 kgf.m, 80 lbf.ft)

If a torque wrench is not used for this installation, see your Honda dealer as soon as possible to verify proper assembly.

1. Recheck drive chain slack.
2. Rear brake pedal free play is affected when repositioning the rear wheel to adjust drive chain slack. Check rear brake pedal free play and adjust as necessary (page 19).

Removal, Cleaning and Replacement

Your motorcycle has an endless (reveted master link) type chain. It should only be removed or replaced by your Honda dealer.

When the drive chain becomes dirty, it should be removed and cleaned prior to lubrication.

1. Clean the side surfaces of the chain with a dry cloth. Do not brush the rubber O-rings. Brushing will damage them. Use of a solvent may also damage the O-rings.
2. Inspect the drive chain for possible wear or damage. Replace any chain that has damaged rollers, loose fitting links, or otherwise appears unserviceable.

Replacement chain:

D.I.D. 520VD

Never use petrol or low flash point solvents for cleaning the drive chain. A fire or explosion could result.

1. Inspect the sprocket teeth for possible wear or damage. Replace if necessary.
2. Lubricate the drive chain.

Wheel Rims and Spokes

(Refer to the Safety Precautions on page 39.)

1. Inspect the wheel rims (1) and spokes (2) for damage.

CLEANING

Clean your motorcycle regularly to protect the surface finishes and inspect for damage, wear and oil and oil or brake fluid 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).

NOTICE

High pressure water (or air) can damage certain parts of the motorcycle.

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 button
■ Under fuel tank
■ Drive chain
■ Carburetor
■ Ignition switch
■ Brake master cylinders

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.

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.

Exhaust Pipe and Muffler Maintenance

When the exhaust pipe and muffler are painted, do not use a commercially available abrasive kitchen cleaning compound. Use a neutral detergent to clean the painted surface on the exhaust pipe and muffler. If you are not sure if your exhaust pipe and muffler are painted, contact your dealer.

Clean the Mat Painted Surface

Using plenty of water, clean the mat painted surface with a soft cloth or sponge. Dry with a soft, clean cloth.

Use neutral detergent to clean mat painted surface.

Do not use waxes containing compounds.

Clean the Seat

Due to the top coat design, the seat surface tends to catch and trap dirt or dust in its texture.

Using plenty of water, clean the seat with a sponge and mild detergent.

After washing, dry with a soft, clean cloth.

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 and clean the filter screen.
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.

! WARNING

Petrol is highly flammable and explosive. You can be burned or seriously injured when handling fuel.

■ Stop the engine and keep heat, sparks, and flame away.
■ Refuel only outdoors.
■ Wipe up spills immediately.

1. To prevent rusting in the cylinder, perform the following:

■ 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.
■ 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.
■ Pour a tablespoon (15 – 20 cm ^3 ) of clean engine oil into the cylinder and cover the spark plug hole with a piece of cloth.
■ Crank the engine several times to distribute the oil.
■ Reinstall the spark plug and spark plug cap.

1. Remove the battery. Store in an area protected from freezing temperatures and direct sunlight. Slow charge the battery once a month.
2. Wash and dry the motorcycle. Wax all painted surfaces. Coat chrome with rustinhibiting oil.
3. Lubricate the drive chain (page 60).
4. Inflate the tyres to their recommended pressures. Place the motorcycle on blocks to raise both tyres off the ground.
5. Cover the motorcycle (don't use plastic or other coated materials) and store in an unheated area, free of dampness with a minimum of daily temperature variation. Do not store the motorcycle in direct sunlight.

Removal from Storage

1. Uncover and clean the motorcycle.
2. Change the engine oil if more than 4 months have passed since the start of storage.
3. Charge the battery as required. Install the battery.
4. Drain any excess aerosol rust-inhibiting oil from the fuel tank. Fill the fuel tank with fresh petrol.
5. Perform all Pre-ride Inspection checks (page 31).
6. Test ride the motorcycle at low speeds in a safe riding area away from traffic.

TAKING CARE OF THE UNEXPECTED

If You Crash

Personal safety is your first priority after a crash. If you or anyone else has been injured, take time to assess the severity of the injuries and whether it is safe to continue riding. If you cannot ride safely, send someone for help. Do not ride if you will risk further injury.

If you decide that you are capable of riding safely, first evaluate the condition of your motorcycle. If the engine is still running, turn it off and look it over carefully; inspect it for fluid leaks, check the tightness of critical nuts and bolts, and secure such parts as the handlebar, control levers, brakes, and wheels.

If there is minor damage, or you are unsure about possible damage, ride slowly and cautiously. Sometimes, crash damage is hidden or not immediately apparent, so you should have your motorcycle thoroughly checked at a qualified service facility as soon as possible. Also, be sure to have your dealer check the frame and suspension after any serious crash.
