GENERAL INFORMATION
Safety regulations
If it is necessary to work on the vehicle with the engine running, make sure that the environment is well ventilated, if necessary using a suitable exhaust system. Never run the engine in closed places since the exhaust gasses are toxic.
The battery electrolyte contains sulphuric acid. Protect your eyes, clothes and skin. Sulphuric acid is highly corrosive; if it comes into contact with the eyes or skin, wash with plenty of water and go immediately to a Doctor.
The battery produces hydrogen which can be highly explosive. Do not smoke and avoid naked flames and sparks near the battery, especially when recharging it.
Petrol is very inflammable and under some conditions can explode. Do not smoke in the work area and keep clear of naked flames and sparks.
Clean the brake shoes, drums and pads in well ventilated areas directing the compressed air jet to avoid taking in the dust caused by the wear on the shoes. Although the brake lining does not contain asbestos, inhalation of the dust is still harmful.
Maintenance rules
Use original PIAGGIO-GILERA spare parts and lubricants recommended by the manufacturer. Spare parts other than originals or that do not conform can damage the vehicle.
Only use the special tools designed for this vehicle. Always use new seals, seal rings and split pins when assembling. After disassembly, clean the components with non flammable solvent. Lubricate all
working surfaces before reassembling, except for the bevel pairs. After reassembly, check that all the components have been installed correctly and
operate perfectly. For disassembly, overhaul and reassembly operations, only use tools with metric
measurements. The metric screws, nuts and bolts are not interchangeable with English measurement couplings. The use of unsuitable tools or couplings could damage the vehicle.
When working on the vehicle electrical system, check the correct assembly of the electrical connections, especially those connecting the to earth and the battery.

TROUBLESHOOTING
Ignition faults are often caused by oxidised or faulty contacts. Check all connections before proceeding. Check whether the battery is sufficiently charged. If the battery charge is inadequate, the starter motor may turn too slowly and the plug will not spark. Furthermore, only spark plugs with correct thermal degree specifications should be used. Disrespect of these precautions may severely damage the engine.
Check the following before troubleshooting;
- faulty spark plug
- badly connected spark plug cap or loose ignition wire connections
- water in the spark plug cap (dispersion of ignition coil secondary voltage) If the plug does not spark, temporarily replace the ignition coil with a spare
in perfect condition and test the spark. If the plug sparks, replace the faulty ignition coil.

RECHARGING SYSTEM AND BATTERY
General
Always turn the ignition switch to C before disconnecting an electrical component.
Important note
Some electrical components can be damaged if they are disconnected - or if their connectors or terminals are disconnected ­with the ignition switch at C and the component is powered.
Remove the battery for long storage periods. Recharge it completely and store it in a cool, dry place. Recharge the battery every two weeks to ensure maximum life.
The battery can be damaged if the charge is too low or too high and also if it is not recharged for a long period of time. These conditions will reduce the battery life. Also in normal conditions of use, the battery performance will deteriorate after two or three years.
After charging, the battery will re-acquire it’s original voltage. The original voltage however will be rapidly reduced and the battery will be completely drained under a considerable load. For this reason, problems of excessive charging may be related to the battery and not to the recharging system as may appear. For example, if a battery cell is short­circuited and the battery voltage does not increase, the regulator/rectifier will provide the battery with excessive voltage leading to an excessive recharging symptom. In these conditions, the electrolyte level will drop rapidly.
Before seeking the fault in the recharging system, you should check the battery conditions of use and maintenance. Check whether the battery has been subjected to frequent, large loads, e.g. if the headlight and taillight were kept on for a long time with the vehicle not running.
The battery will discharge autonomously when the vehicle is not in use. For this reason, recharge the battery every two weeks to prevent sulphating.
When checking the recharging system, follow the instructions indicated in the troubleshooting flow chart (section 2 of this manual).
The alternator can be serviced also with the engine fitted in the frame.

Warning
The battery electrolyte contains sulphuric acid, it is poisonous and can cause serious burns. Avoid contact with the eyes, skin and clothes. If it comes into contact with the eyes, wash with plenty of water for 15 minutes and go to a Doctor as quickly as possible. If the liquid is swallowed, drink a large quantity of water or milk immediately, swallow milk of magnesia, beaten egg or vegetable oil. Call a Doctor immediately. The gas coming from the battery during recharging could explode under certain conditions. Keep well clear of sparks, naked flames or cigarettes. Ventilate the environment when recharging the battery. Always shield the eyes when working near batteries. Keep out of the reach of children.
BATTERY MAINTENANCE
The battery is the electrical component that requires the greatest care and the most diligent maintenance. The most important maintenance prescriptions are;
1) Checking the electrolyte level. The electrolyte level should be checked frequently. It should reach the upper level. Use distilled water only for topping up.
Check the vehicle electrical system if frequent topping up is required because the battery is being over-charged and will deteriorate rapidly.
2) Checking the charge. Check the electrolyte density after topping up the level with a specific tool (see fig opposite). The density should be 30-32° Bé when the battery is fully charged which corresponds to a specific weight of 1.26 -
1.28 at a temperature higher than 15°C. If the density is lower than 20° Bé, the battery is completely flat. Recharge it. When the battery is being charged, the voltage in each element should be 2.6 - 2.8V. The discharge limit in each element is 1.8V. At the end of the recharge, check electrolyte level and density as well as the voltage in each element. Recharge the battery regularly if the vehicle is not used for a certain period of time (over one month). The battery will be completely drained after three months of storage. Be careful not to invert the connections when refitting the battery in the vehicle. The earth wire (black) with the (-) reference mark should be connected to the negative terminal (-) while the other two red wires with the (+) reference mark should be connected to the positive (+) pole.
3-2,1
PREPARING CHARGED-DRY CELL BATTERIES FOR USE
1) Remove the short closed tube and the caps. Pour sulphuric acid into the elements to reach the upper level (amount for battery with a specific weight of 1-26 corresponds to 30° Bé at a temperature higher than 15°C).
2) Leave to rest for two hours.
3) Charge at an initial intensity equal to approximately one tenth of the battery capacity until the voltage reaches a value of approximately 2.7V in each element. The electrolyte density should be approximately 1.27, which corresponds to 31° Bé. The values should be stabilised and the recharging operation should take from 15 to 20 hours.
4) After recharging, top up the electrolyte (with distilled water - remove any acid in excess). Cap and clean accurately.
5) Finally, fit the battery in the vehicle respecting the connections.
REMOVING THE BATTERY NOTE: Always turn the ignition
switch to C before removing or in­stalling the battery.
- Remove the side fairing.
- Remove the two screws and the battery bracket.
NOTE: Always disconnect the negative battery first and then the positive terminal from the battery.
- Remove the bolt and the negative battery wire then the positive wire cap, with the respective bolt and the wire.
- Remove the battery
REFITTING THE BATTERY
- Reverse the removal sequence to refit the battery. Apply grease to the terminals.
CHECKING THE BATTERY CHARGE
- Measure the battery voltage with a digital multimeter.
VOLTAGE: Fully charged: over 12.8V Insufficient charge: under 12.3V

- Connect the negative wire (-) on the battery charger to the negative terminal (-) on the battery.
CURRENT/RECHARGING TIME Slow recharging: 0.7 A / 5 - 10 hours Quick recharging: 5.0 A / 1.0 hour maximum
Warning
The gas released by the battery during the recharging process can explode in certain conditions. Keep sparks and sources of heat away from a recharging battery. Remove the battery from the vehicle by disconnecting the negative (-) terminal first.
- After refitting the battery in the vehicle and connecting the terminals to the electrical circuit, protect the terminals with electrical contact grease.
TOOLS
Battery charger (single) 445492
Battery charger (multiple) 445493
Important note
Use a quick battery recharge only in an emergency. The slow recharge cycle is preferable. Do not exceed the specified current and the recharging time shown on the battery. Excessive current or longer recharging times can damage the battery.
INSPECTING THE RECHARGING CIRCUIT NOTE: The multimeter can be damaged if used to measure circuits with
…………a higher capacitance than that of the device. Before starting, set ………….the multimeter to the maximum load and reduce it progressively ………….to obtain the correct setting without damaging the tool.
CHECKING THE REGULATED VOLTAGE
- Remove the battery and fit a fully charged battery in its place;
- Start the engine and take it to running temperature. Stop the engine.
- Connect the multimeter between the positive and negative terminals.
Important note
Do not confuse the positive and negative battery terminals to prevent short-circuits. Do not disconnect the battery or a recharging system wire before switching off the ignition switch. Disrespect of this precaution can damage the multimeter and the electrical systems.
3-2,3
- Switch the headlight on and start the engine.
- Read the voltage on the multimeter with the engine idling at 5000 rpm.
REGULATED VOLTAGE 14.0 - 14.8 V at 5000 rpm
- The battery is in good condition if the value read on the multimeter corresponds to the regulated voltage.
NOTE: The speed at which the voltage starts increasing cannot be measured as it varies according to the temperature and the alternator load.
- A battery which drains often is to be considered deteriorated, after excluding other problems to the recharging system, even if the outcome of the regulated voltage test is OK. The presence of one of the following symptoms may indicate a possible fault in the recharging system.
1. Voltage lower than the registered value
Recharging system wiring broken or short-circuited or faulty contacts in a connector. Alternator broken or short-circuited. Faulty regulator/rectifier.
2. Excessive regulated voltage
Faulty regulator/rectifier connection to earth. Faulty battery. Faulty regulator/rectifier.
SEARCHING FOR DISPERSION
Disconnect the battery earth wire (-). Connect the positive ammeter probe (+) to the battery earth wire and the negative ammeter probe (-) to the negative (-) battery terminal.
- Turn the ignition switch to C so to power the circuit.
- Turn the emergency switch to C to prevent reading the control unit power current.
- Engage a gear and keep the side stand up so to prevent powering the respective warning lights.
NOTE: Before starting , set the multimeter to a high load and re­duce it progressively so to obtain the correct setting. A flow of cur­rent exceeding the selected load can blow the multimeter fuse. When measuring the current, switch the direction indicators and the lights off.
PRESCRIBED CURRENT DISPERSION 0 mA max.
- If the current dispersion exceeds the set value, there is probably a short-circuit. Locate the short-circuit by disconnecting the connections one by one and measuring the current.
Check that there is no dispersion in the system.
3-2,4
REGULATOR/RECTIFIER Checking the wiring
- Remove the tank.
- Disconnect the regulator/rectifier 2-pole connector. Then check that the terminals are not loose or corroded.
BATTERY CIRCUIT
Make sure that there is voltage between the red wire (+) and the black wire (-). If there is no voltage, check the following;
Item
Battery charging wire Earth wire
Connector
(+) red & (-) earth
Black and (-) earth
Standard values
Battery voltage
Continuity
If the outcome is different, the problem is in the wiring.
RECHARGING CIRCUIT NOTE: You do not need to remove
the stator winding to carry out this test.
- Disconnect the 2-pole connector connecting the regulator/rectifier and the alternator.
- Measure the resistance between each of the connector terminals and the other two.
CONNECTION: Yellow and yellow VALUE: - 0.8 Ω (20°)
- If the recharging coil resistance is out of specifications, check the continuity between the connector terminals and earth. There should be no continuity. If there is continuity between the connector yellow wire and earth, replace the stator. If there is no continuity, proceed with the voltmeter checks on the stator, described in chapter 11, engine manual.

GENERAL RULES FOR OPERATION ON THE BRAKE
HYDRAULIC SYSTEM
Warning
If the liquid accidentally contacts the eyes, wash with plenty of water and seek medical advice immediately.
Used hydraulic oil is harmful for the environment and must be collected and disposed of in accordance with the law.
NOTE: When topping up or replacing, use only DOT4 - NHTSA 116. Ensure perfect cleanliness. Hydraulic oil is very corrosive on painted surfaces.
The braking system fluid is hygroscopic, which means it absorbs the moisture from the air. If the moisture in the brake fluid exceeds a certain value, braking becomes inefficient since the boiling point of the liquid is reduced.
NOTE: Always take the fluid from sealed containers. Under normal driving and climatic conditions, the fluid should be replaced
every two years. If the brakes undergo serious strain, replace the fluid more frequently. When refitting, the parts that are used again must be perfectly clean and
free from oil, diesel or grease, therefore they are to be carefully washed with denatured alcohol.
NOTE: Do not leave rubber parts in the alcohol for more than 20 seconds. After washing, dry the parts with compressed air and a clean cloth.
Warning
braking efficiency. In such cases, replace the pads and clean the disc with a good quality solvent.
Hydraulic oil is corrosive. Always wear protective gloves.
Brake fluid on the disc or the brake pads decreases
REPLACING THE REAR BRAKE CALLIPERS
Remove the rear wheel by loosening the wheel axle nut and removing the wheel axle. Remove rear brake retaining bar from the calliper holder plate. Remove the brake control wire and move the chain aside.
Remove the rear wheel. Remove the callipers with a lever, if required. Replace the brake callipers and refit by reversing the removal sequence.
6-1
DISASSEMBLING THE FRONT BRAKE SHOE
Loosen the fitting screw and disconnect the hydraulic pipe. Collect the brake fluid in a suitable container.
Loosen the two Allen screws and disconnect the brake shoe assembly from the fork.
Replace the brake fork assembly, top up the oil level and bleed the system.
TIGHTENING TORQUE Brake shoe fitting
13 ÷ 17 Nm (1.3 ÷ 1.7 kgm)
Brake shoe to fork
20 ÷ 22 Nm (2.0 ÷ 2.2 kgm)
REPLACING THE FRONT BRAKE PADS
Loosen the pad plate central screw to allow it to move. Remove the two pins and release the pads. NOTE: When refitting the new pads you will need to insert the pistons in their housings. Be careful not to damage the pistons or the shoe body when doing this.
Insert the pads, the pins and the plate And torque the screw.
6-2
REPLACING THE FRONT BRAKE CYLINDER
Disconnect the brake oil pipe from the shoe and drain the oil by pumping the brake lever. Disconnect the pipe on brake cylinder side. Release the complete brake cylinder after loosening the two Allen screws. Refit, top up and bleed the system.
TIGHTENING TORQUE Front brake cylinder U-bolts
6 ÷ 7 Nm (0.6 ÷ 0.7 kgm) Front brake pipe fittings to cylinder and to shoe
13 ÷ 17 Nm (1.3 ÷ 1.7 kgm)
FILLING & BLEEDING THE BRAKE SYSTEM
Arrange the vehicle in vertical position with the pipe correctly connected both to the cylinder and to the brake shoe. Fill the system with the prescribed fluid. Apply the specific tool (manual Mityvac pump) to the bleeder fitting on the brake shoe. Operate the specific tool and pump the Brake lever at the same time. Top up the oil reservoir constantly to prevent taking in air. The operation ends when only oil is let out of the bleeder. Fasten the bleeder screw at the correct torque.
NOTE: If air continues to be expelled during the bleeding operation, check all the fittings. If no fault are found there, check the brake cylinder and the shoe. During the bleeding operation, the brake lever may need to be adjusted. This is because if the brake cylinder is too far forwards or backwards, either the cylinder may not be recharged correctly or the fluid pressure may drop in the circuit.
Important note
During this operation oil may seep out from the breather screw onto the shoe and the disc. In this case carefully dry the shoe and degrease the disk.
TIGHTENING TORQUE Bleeder screw 8 ÷ 12 Nm (0.8 ÷ 1.2 kgm)
SPECIFIC TOOL Manual pump 19.1.20329
CHECKING AND REPLACING THE FRONT BRAKE DISC
Remove the front wheel. Check that the brake disc is not deformed or scratched. If faults are found on the brake disk, replace by means of the screws shown in the figure.

Important note
The battery is to be charged before use to ensure maximum performance. If the battery is not fully charged before the first use at low electrolyte level this will cause premature battery failure.
Warning
Before charging the battery remove the caps from all elements. Keep clear of naked flames and sparks during battery charging
Important note
When removing the battery from the vehicle disconnect the negative cable first. When installing the battery, fix the positive cable first, then the negative.
Warning
The battery electrolyte is poisonous and causes serious burns. It contains sulphuric acid. Do not allow it to contact the eyes, skin or clothes. If it contacts the eyes, wash with plenty of water for about 15 minutes and go to a Doctor as soon as possible. If the liquid is swallowed, immediately drink lots of water or vegetable oil. Call a Doctor immediately. Always shield the eyes when working near batteries.
Important note
Never use fuses with a higher amperage than that recommended. The use of a fuse with an unsuitable amperage can cause damage to the vehicle or become a fire hazard.
Important note
The tyre inflation pressure is to be checked and adjusted with the tyres at ambient temperature. Do not exceed the specified inflation pressure as this could cause the tyre to burst.
