Scooter repair Honda (Honda)

High-quality maintenance and professional repair of Honda scooters is our daily work, which we treat carefully and with love. There are no random people in our service, only experienced auto specialists. We will fix all known types of breakdowns, carefully tighten each screw and tune your “horse” so that it sounds like an expensive musical instrument.

When you contact our service, we will advise you in detail on all “burning” issues. But we would like you to understand your Honda scooter a little better and to at least roughly determine what is wrong with it.

Perhaps you will independently adjust any of the nodes, and our service station will not earn a small amount of money. We will be warmed by your feeling of gratitude for the fact that we have created this rather detailed instruction. Naturally, in difficult cases, we strongly recommend not to “self-medicate” and contact the professional masters of our service.

List of standard breakdowns and adjustments of Honda scooters

We will list the main problems that can happen with your vehicle and dwell on each of them in more detail. So, the main components of a Honda scooter that usually require repair are:

Engine.

Repair of the engine (motor) of the Honda scooter

Like any mechanical unit, a Honda scooter engine has a limited life. After a certain mileage has been run, its resource is exhausted, and it starts to malfunction or stops working altogether. You can understand that the motor needs urgent repair by some signs:

the exhaust fumes have changed from their usual color to black or gray;

uneven operation of the unit (usually at high speeds);

the consumption of fuel, oil and antifreeze has significantly increased (all together or separately);

the pressure in different cylinders is much different;

In many cases, an experienced driver or auto technician can determine the problem from the operating sound of the engine. For example, if the “insides” of the engine are worn out, then the power of its sound increases and changes the tonality. This is clearly audible during acceleration, at maximum speed or at idle.

The transmission of the rotational motion of the engine to the rear wheel is carried out with the participation of a gearbox. The task of this unit is to reduce the speed of the transmitted rotation while maintaining maximum power at all speed ranges. The main working element of the gearbox is a system of gears and bearings. The functional problems of the mechanism can be judged by:

characteristic noise, the sound of which is different from normal, or grinding;

strong vibration (beating) of the driven and driving shafts;

obvious and tangible interruptions in the transmission of torque or complete stop of the unit;

the presence of drips of transmission oil, which usually “speak” of problems with gaskets or oil seals.

Most often, when repairing a Honda scooter gearbox, a complete or partial replacement of the most wearing parts, bearings, gears or bushings, a little less often. shafts is carried out. In theory, you can disassemble this fairly simple unit yourself and try to fix it. However, there are always a lot of nuances. and only our pros know about them.

Honda scooter carburetor repair

A carburetor is an important and rather fragile unit of a motor vehicle, in which the process of “preparing” a combustible fuel-air mixture for engine cylinders takes place. Its “filling” is very sensitive to dust and dirt particles that penetrate inside along with gasoline or from the environment. If the carburetor is defective:

the engine may not start or stall;

instability of engine speed is observed, stable “dips” appear;

We recommend that you carry out a regular visual inspection of the carburetor, as well as maintenance after every 500 km, which consists in thoroughly cleaning and rinsing it. The fact is that gases, vapors of resins and oils clog channels, filters, jets and other key elements. In addition, the carburetor will not work properly if adjusted “by eye”. Noticing problems with your new or recently refurbished device? Our masters will carry out high-quality fine adjustment of your carburetor, namely:

adjust the idle speed stabilization system;

using a needle or a special screw, they will adjust the quality of the combustible mixture;

adjust the rate of fuel supply to the combustion chamber;

restore the correct level of fuel in the float chamber.

The variator is sometimes called a centrifugal clutch, in fact, this device is designed to transmit torque and change it smoothly in a given range. The main symptoms of a malfunction:

poor ride and low traction at the start;

slow acceleration and constantly stalling engine;

extraneous noises and odors while driving.

The most common failures are the drive belt / pulley, spring, rollers or bushings. Important: to increase the service life and smooth operation of the variator of the Honda scooter, entrust our specialists with its annual disassembly, prevention and replacement of the most worn parts.

Repair of the starter of the Honda scooter (Honda)

This element provides a quick and convenient engine start by pressing a button. If it does not work, then first you should check the battery charge level. Is the battery charged but the engine won’t start? So the problem is different:

damaged contact group or relay coil;

malfunctioning of one of the wiring elements (clutch contacts, starter buttons or others)

In this case, it is necessary to replace worn-out spare parts or a non-working unit entirely. The Honda scooter starter also needs to be cleaned regularly to remove dirt.

Repair of the kickstarter of the Honda scooter

A kickstarter or, in a simple way, a “winding leg” will help in cases when the battery is discharged or the electric starter is broken. you can safely ride your scooter to our service or home. This useful mechanism fails if:

the driver was sloppy and made excessive efforts;

the leg is made of low quality metal;

there is a problem with the variator cover;

In the first 2 cases, the spare part must be replaced, in the 3rd and 5th. it is necessary to weld or change the elements, in the 4th. to reassemble the leg. If the kickstarter does not return to its original position, it can be cleaned, rinsed and thoroughly lubricated or replaced.

The cylinder-piston group is one of the most important and most reliable units, the problems of which the driver usually learns about the changes in the sound of the engine and other signs:

unusual noises and knocks “speak” of a malfunction of the pistons, piston pin, rings or the cylinders themselves;

when gaining speed, power decreases;

the Honda scooter responds poorly to turning the throttle and does not always start;

Remember that the CPG usually changes completely. Only in some cases, when the piston is in perfect condition, is it allowed to bore the cylinder and install only a piston with rings.

The purpose of this structural element is to convert the reciprocating energy of the piston movement of the CPG into rotation, which is then transmitted to other units (generator, gearbox, clutch and rear wheel). Signs of the need for diagnostics:

The crankshaft is made of durable steel, so it is rarely completely replaced, but its bearings and seals are subject to wear, so they should be purchased periodically. Maintenance of the crankshaft requires precision and 100% compliance with technological procedures, which is extremely difficult at home.

Tip: Add oil to the crankcase regularly to avoid contamination, increased viscosity and loss of ability to properly lubricate parts.

In addition to reducing noise from exhaust gases, the muffler also performs a number of important functions. For example, it serves as a kind of valve that is responsible for engine power. A muffler breakage is usually determined by the following features:

As a rule, the main problem of mufflers is the clogging of the channels with the remains of burnt fuel and oil. Checking the knot is quite simple: blow into the inlet. If air does not pass freely, urgent cleaning is required. This process can be carried out by the methods of “folk craftsmen”, but in case of serious pollution, it is preferable to contact our service station, otherwise you will have to completely change this element.

Repair of the front fork of the Honda scooter (Honda)

The main purpose of the front fork with shock absorbers is to ensure a comfortable ride and excellent controllability of the scooter, smoothing out unevenness in the road surface. You will understand that a part needs repair or replacement when:

even begin to feel small bumps or pits;

the front fork shock absorber will start to jam and will not stop independently recovering to its original position.

noticeable distortions between both sides of the node.

You may just need to clean the elements of the front fork structure from dirt and dust, but it is advisable to carry out a professional diagnosis of each part for the degree of wear. Remember that when disassembling the mechanism, you should carefully remove the stiff springs, which can “shoot” and injure.

Repair of the shock absorber of the Honda scooter

The main task of the rear shock absorbers is to absorb the various shocks, shocks and vibrations that the scooter “catches” while driving, as well as to provide reliable traction. The symptoms of a component failure are similar to those of the front fork. Sometimes in the rear shock absorbers it is necessary to replace the main working elements. silent blocks. To understand if the replacement of silent blocks is required:

Suspend the rear wheel by placing your Honda scooter on the footboard;

If there is a clear backlash or lateral displacement, urgently contact our service for a more accurate diagnosis and repair. Important: Damaged shock absorbers not only reduce ride pleasure, but can also lead to loss of control.

The ignition system is used to transfer generator voltage to the spark plugs. The switch and the ignition coil can be made in one unit or separately from each other. Most often, one or more key elements of the system break down:

the ignition lock, ignition unit (switch), coil and sensors are always replaced with new parts, since they cannot be repaired;

the high-voltage wire should be selected from good steel, and car wires are usually not suitable for Honda scooters;

the spark plug produces a high-power spark that ignites the combustible mixture in the engine. Carbon build-up or improper installation of the cap may prevent proper ignition.

To avoid early or late ignition of the fuel-air mixture, the ignition system needs to be set. If you have a scooter registration certificate and certain skills, you can do it yourself. Remember that this process is very specific and requires professional experience.

Repair of the electrical wiring of the Honda scooter

The electrical wiring acts as a kind of “circulatory” system of the scooter. She is responsible for the transfer of electric current between the battery, generator and other elements, which include:

The complexity of wiring diagnostics is due to its length and the inability to visually determine the problem area if it is not a clearly visible wire break. If, for example, a turn signal fails, it is necessary to check the integrity of the entire corresponding electrical chain, sequentially measuring the current strength. Usually this task is entrusted to experienced auto electricians who are equipped with the necessary equipment and wiring diagrams for a specific model of a Honda scooter.

The shiny, bright and colorful beauty of most of the body and other parts of your scooter is made of plastic. This also applies to those elements that look metallic, for example, protective parts of the frame, but in fact are simply painted in a special way. The main signs that the details of the body kit require attention:

there was a backlash and extraneous rattling sounds;

excessive contamination of surfaces, especially oily and chemical compounds;

the presence of deep scratches, chips and potholes, for example, from gravel;

cracking from the influence of low or high temperatures.

Backlash is eliminated by simply tightening the mounting screws, the use of auto chemicals (polishes, cleaners, shampoos, detergents and corrective pencils) easily solves the problem of dirt and minor damage. In more serious cases, you will have to completely change the body kit part. If you take proper care of the plastic of your Honda scooter, it will last a long time.

Repair of the generator of the scooter Honda (Honda)

The generator is included in the ignition system and is responsible for the “supply” of the required amount of electricity to the high-voltage coil for the subsequent ignition of the spark. Also, the generator generates an electric current, due to which electrical appliances operate. The reasons for the breakdown of this unit include:

poor connection and insulation of cables;

low level of magnetization of the rotor elements;

Due to the unsatisfactory operation of the generator, there is a low charge and rapid discharge of the battery, a weak spark, and dim lighting. Using a multimeter, you should check the parameters of the output voltage of the generator itself, the switch, the performance of the unit without load.

Repair of the clutch pads of the Honda scooter

In the process of performing their tasks, the clutch pads diverge and interact with the bell of the rear variator, after which the vehicle begins to move. The result is centrifugal force, which over time destroys the pads, making them thin. Their wear may be evidenced by:

unjustified increase in engine speed at the start;

the presence of strong jerks while driving;

All these signs are indirect, but they indicate the need for repairs. We recommend annually checking the condition of the clutch pads, if necessary, replacing them at our workshop.

The purpose of the braking system is well known. to ensure the safety of the driver and passengers of the motor vehicle. Malfunctions with the brakes can only be detected while driving, therefore, their serviceability should be treated with special care, regularly carrying out maintenance and repairs. The scooter owner should closely monitor:

the quality of the brake fluid and its sufficient quantity;

no leaking hoses and connections;

the level of rusting of metal elements.

Easy (and cheap) way to bleed hydraulic scooter disk brakes.

It is important to remember that the brake fluid must be changed at least once every 8-11 months, adding it to the reservoir. The pads are replaced when they are worn out to 2 mm, and the hoses. when cracks or damage appear on them.

The automatic centrifugal clutch system, which is used in scooters, provides a smooth start, transferring the speed from the engine to the gearbox. The symptomatology of breakdowns is described in clause 16, which deals with clutch pads.

The frictional force that acts on the clutch elements during operation exposes them to wear. We recommend that you check the system every year or more often, replacing defective parts with new ones.

Honda scooter battery repair

The storage battery is the basic element of the entire electrical system of the motor vehicle, which accumulates electricity and gradually transfers it to other components. Starting the engine, lighting, feet, signal and indicators. all this will not work without a battery. Like any battery, this unit can:

If the battery is not performing well, check the contacts. It may be necessary to clean the terminals of oxides or tighten them well. Also, periodically recharge the battery with a special device, especially during periods of inactivity. It is easier to replace a non-working “device” or give it to the masters of our service who will try to revive it.

The material and instrumental base of our service and the level of training of auto specialists allow us to work with a variety of models of Honda scooters (Honda), including: DIO AF 18, DIO AF 25, DIO AF 27/28, DIO AF 34/35 (ZX), DIO AF 54, DIO AF 56, DIO 110 JF-31, SMART DIO AF-56/57, ZOOMER AF-58, DIO AF 62, DIO AF-63 Z4, DIO AF 68 (INJECTOR), DJ-1 (AF-12). GIORNO AF-24, GIORNO CREA AF-54, GIORNO AF-70, CREA SCOOPY AF-55, GYRO CANOPY, LEAD AF 20 (50CC), LEAD AF 48 (100CC), LEAD HF05 (90CC), LEAD 90 HF- 05, LEAD 100 JF-06, LEAD 110 JF-19, PAL AF 17, PAX AF14, SH 125/150, TACT AF 09, TACT AF 16, TACT AF 24, TACT AF 30/31, TACT / JULIO AF 51 / 52, TODAY AF-61/67, TOPIC AF 38, SPACY 100, FORZA 250, SILVER WING 400/600, SILVER WING GT.

Wheels

The wheels are “dressed” in native Japanese rubber, the size of the front wheel is 3.5 inches by 10, the rear wheel is also 3.5 by 10. The suspension is combined. the front wheel is on a pendulum lever fork, the rear wheel is on a shock absorber with a spring.

Dimensions and weight

The scooter is 1755 mm long, 715 mm wide and 1060 mm high. Dry weight does not exceed 85 kg.

Description and features of the scooter Lid AF 20

Honda Lead AF 20 has a rather impressive body, it allows two riders to comfortably fit on it. Although, of course, a scooter will not be able to realize all its power with two people on the seat. Alone, the driver easily accelerates the vehicle up to 60 km / h, and with the accompanying conditions and more.

Performance Indicators

Before leaving the garage, it makes sense to inspect a number of systems and blocks in the scooter’s mechanism. First of all, this is the brake, it is easy to check when you press the lever. the wheels should lock.

The tires themselves must be inflated to 1.8 atmospheres, if 2 people are supposed to sit on the seat, then up to 2 atmospheres.

When boarding a moped, you need to push it forward a little, without removing the brake, thus, the operation of the shock absorber is checked, it should not creak or leak.

Next, the scooter needs to be refueled, it takes 92, 93 and 95 gasoline.

It is impossible to pick up the maximum speed right away, the engine needs to warm up at least 1-2 kilometers, the speedometer should show no more than 30 km / h, then you can add up to the prescribed 60 km / h.

Ignition on the scooter is double, you can start the starter from the button or, if the engine is cold, use the foot kick starter.

It is necessary to change the plug in the engine regularly, every 5000 km. Pads are replaced when noticeable abrasion and characteristic sound appears.

Available spare parts

There are also tuning items, such as a rearview mirror, front fender or glass above the dashboard.

Brake system

The brakes on the front and rear wheel are different. The front wheel is equipped with a disc brake, and the rear wheel is equipped with a drum.

How much adrenaline is in your blood

Honda Lead AF 20 is equipped with an AF 20 engine with 6.4 horsepower. The mileage resource is 100,000 km, which is very good for a scooter.

Reliability and build quality are common features of these mopeds

Another distinctive feature of the scooter is the headlights. Like the big road choppers, the headlight and tail light each have 2 bulbs. This makes the headlights brighter, more reliable, it becomes possible to work on high and low beam.

The dashboard of the small scooter is very informative and easy to use. The device has two places for storing tools and things. under the steering wheel and the driver’s seat.

What is a switch and why is it needed?

To put it simply, a switch is a kind of module (according to Feng Shui. a DC CDI or AC CDI module) in which electric energy is accumulated, which at the right moment is supplied in the form of a pulse to the ignition coil, where it is multiplied many times and slips in the form of an electric spark between spark plug electrodes.

Depending on the type of switches, the energy required to form eggs can be stored in the switch in two ways:

  • On switches of the AC CDI type. the energy required for the formation of a spark on the spark plug is first formed in the high-voltage coil of the generator and then, in the form of an alternating current, it enters the switch, where it is accumulated in the capacitor and at the right moment in the form of a pulse is fed to the ignition coil
  • On DC CDI switches. the energy required to form a spark on the spark plug in the form of direct current comes directly from the battery, where it is converted into alternating current, multiplied by voltage and goes to the capacitor

The switch power coils on the generator look something like this. On some models of generators there are two, on some there is only one

For the passage of a spark at the right time, a magnetic induction sensor (in collective farm style. “hall sensor”) is introduced into the design of the generator and the switch like it. The magnetic induction sensor is essentially a conventional alternator, only in miniature.

On the outer side of the generator rotor there is a small ledge, when passing near the sensor. a small alternating pulse is formed in the sensor windings, which is fed to the switch thyristor. the thyristor opens and the energy accumulated in the capacitor enters the ignition coil

Switch test

In order not to waste time. the check should start with checking the electrical impulse, which accumulates in the switch and at the right time goes to the ignition coil.

We take a control light and connect it with one end to the green ground wire, the second to the black and yellow wire of the ignition coil. We turn the engine with a starter.

  • If the light is off, we check the modules that ensure the operation of the switch
  • If the light comes on, the switch and the modules that ensure its operation are in good working order and the reason for the absence of a spark should not be looked for in the switch, but for example in the ignition coil, ground or wires supplying current to it

With a working switch and modules that ensure its operability, a 3W light bulb in the engine cranking mode with a starter should be lit in the glowing floor

Weight check

If there is any suspicion of a malfunction of any scooter ignition module, the mass is first checked. Although, mass in two-wire wiring is a relative concept, but for now let’s call this thing like this.

We take the tester, put it into the “dialing” mode (diode icon or sound signal icon), look for green wires on the switch. this is something other than mass (in Feng Shui. a negative wire), with any tester probe we touch the metal part of the engine, others poke a probe into the green wires:

  • If there is mass, the tester will beep
  • If the mass is bad, numbers will run on the tester display
  • If there is no mass, the tester will be silent, and there will be only zeros on the screen

Depending on what the tester shows you. troubleshoot or continue testing:

  • If the mass is bad, look for an open or oxidation in the wiring.
  • If there is no mass. look for a break or connect it directly from the engine
  • If there is mass, but there is no spark, we continue to check.

An example of a good mass: the tester beeps in the “dialing” mode, the display shows solid zeros

Photo report: How to check the scooter switch?

Friends, do not flatter yourself strongly. The Internet, in particular, this site is only intended to help you in solving a particular problem. And the rest will depend only on you, or rather only on your desire and nothing else.

Tools

  • Tester with sound “dialing” mode and measuring range of DC up to 20V, AC. 2, 200V
  • Control light 3W

Checking the generator sensor

The magnetic induction sensor is a key element of the ignition system. And if there is any suspicion of a malfunction in the ignition system, it should also be checked.

We switch the tester to the alternating current measurement mode for the 2V range. With one probe we touch the ground, with the second probe we touch the white-blue or red-yellow wire coming from the sensor and turn the engine with a starter.

  • If the numbers run on the screen, there is an impulse
  • If there are zeros on the display, check the sensor

Power check

In order for a spark to slip between the electrodes of the candle, the capacitor of the switch must be charged from something. And it is charged either from the battery or from the generator. Means what? Correctly! Checking if the switch is receiving power.

Before you start measuring the power, we determine what type of switch is on your scooter. Visually, DC CDI switches are twice as large as AC CDI. But this is not a precise criterion. The most accurate criterion. see the output of the high-voltage coil of the generator:

  • If it is not used, it means that your scooter is equipped with a DC CDI switch.
  • If it is, then vice versa. your scooter is equipped with an AC CDI type switch

The output of the high-voltage coil of the generator is located in the same place as the output of the generator itself: we are looking for where the wires coming from the generator are connected to the on-board network of the scooter and if one of the two wires with round terminals is not connected, then the coil is not involved

Model HF05

The second most popular scooter was the “Honda Lead 90″ scooter, also created in 1988. The two-seater scooter was produced under the brand name HF05.

  • fuel consumption. 1.85 liters per 100 km at a speed of 50 km / h.

The next development of the company “Honda

In 1998, the production of another model of the popular scooter began. It was a Honda Lead 100 two-seater scooter. The new car was distinguished by its streamlined shape and a large headlight in one block with the “turn signals”. The cladding made of quality plastic, smoothly wrapped around the wide double seat, gave the impression of solidity and good design.

The headlights include a powerful reflector with two built-in halogen lamps, creating a double, sharp beam of light that covers the area in front of the scooter sixty degrees wide. The taillights are not so powerful, their design corresponds to low-speed scooters, when powerful brake lights and turn signals do not make sense, 10-15 watt bulbs are enough.

How to choose a model

The most popular modifications from the Lead Honda lineup are “50cc” and “90cc” versions. Both scooters are assembled in the same body, but the engine power differs significantly. The thrust of the motor and you need to be guided first of all. Some buyers will be satisfied with the engine power of 5 liters. from. (50 cc / cm), most scooters are equipped with such. For owners who are accustomed to driving together, it is better to purchase the HF05 model with an 8 hp engine. with., which according to all data surpasses the 50-cc.

Comfort and dynamics

When the Honda Lead scooter was created back in 1982, it instantly became a bestseller. The small car did not even need an introduction, it had such perfect technical characteristics that customers lined up for a scooter that looked like a toy and weighed only 64 kilograms.

Leadership

The scooter “Honda Lead” in the entire history of production was considered the most successful model among its kind. The model is still in the lead today, thanks to its exceptional technical characteristics.

Initially, the scooter was created for intensive use, therefore, parts of increased strength were immediately incorporated into the design. Therefore, the car turned out to be super reliable, with a long resource and durability. The operational data of the scooter provide a high degree of cross-country ability, which is sometimes of no small importance. At the same time, the engine does not suffer from dust, dirt and other external factors, since clean air enters the carburetor from under the seat. The scooter is quite suitable for use on country roads. In winter, the car can overcome snow cover up to twenty centimeters thick.

The company “Honda” from the first days of the release of the scooter took care of high-quality and varied painting. Initially, the classic white and black colors in various combinations were taken as a basis, and then they began to use a range of twelve colors. Variety of vibrant color combinations have greatly increased the attractiveness of small two-wheeled vehicles and have had a positive impact on sales.

Running parameters

The undoubted advantage of the scooter is its chassis, rationally designed brakes and suspensions. Front brake. disc, ventilated, very efficient. The rear drum, which works softly, never wedges, turns on with a slight delay relative to the front one, and thus the scooter stops in a split second, without skidding and skidding.

The scooter is equipped with a Nissan brake system that never fails. The front suspension is a powerful link-type fork combined with a hydraulic shock absorber. It does not give rise to any complaints, but it requires attention when entering a sharp turn. If the speed is higher than optimal, the suspension arm will vibrate and the scooter may lose control. Therefore, when driving on a winding road, you must observe the minimum speed.

Telescopic front suspensions were installed on some models produced in 1999, but they did not take root, since they had to work within a limited amplitude and high loads often caused the unit to break. In addition, such a suspension was stiffer, in contrast to the lever suspension and “caught” all the irregularities, causing shaking.
