1.2. GENERAL RULES
1.2.1.
BASIC SAFETY RULES
CARBON MONOXIDE
Should it be necessary to perform some operations with the vehicle running, make sure to work outdoors or in a wellventilated room.
Avoid starting the engine in closed or badly-ventilated rooms.
In case you are working indoors, make use of an exhaust gases scavenging system.
DANGER
Exhaust gases contain carbon monoxide, which is extremely toxic if inhaled and may cause loss of
consciousness or even lead to death by asphyxia.
FUEL
DANGER
The fuel used to operate engines is highly flammable and becomes explosive under particular
conditions. Refueling and engine service should take place in a well-ventilated area with the engine
stopped. Do not smoke when refueling or in the proximity of sources of fuel vapors, avoid flames,
sparks and any element that could ignite fuel or provoke explosions.
DO NOT DISPOSE OF FUEL IN THE ENVIRONMENT.
KEEP AWAY FROM CHILDREN.
HIGH-TEMPERATURE COMPONENTS
The engine and the exhaust system parts become hot and continue to be hot even for some time after the engine has
been stopped.
Before handling these parts, wear heatproof gloves or wait for the engine and the exhaust system to cool completely
down.
USED GEARBOX AND FORK OILS
DANGER
In case any maintenance operation should be required, it is advisable to use latex gloves.
Gear oil may cause serious damage to the skin if handled daily and for long periods.
Wash your hands carefully after use.
Put it in a sealed container and take it to the filling station where you usually buy it or to an oil salvage
center.
In case any maintenance operation should be required, it is advisable to use latex gloves.
DO NOT DISPOSE OF OIL IN THE ENVIRONMENT
KEEP AWAY FROM CHILDREN.
BRAKE FLUID
WARNING
When using the brake fluid, take care not to spill it on the plastic, rubber or painted parts, since it can
damage them.
When carrying out the maintenance operations on the braking system, use a clean cloth to cover
these parts.
Always wear eye protectors when working on the braking system.
The brake fluid is highly irritant. Avoid contact with your eyes.
If the brake fluid gets in contact with the skin or the eyes, carefully wash the parts of your body that
get in contact with the fluid and consult a doctor.
KEEP AWAY FROM CHILDREN.
COOLANT
The coolant is composed of ethylene glycol that, under certain conditions, can become inflammable and send out
invisible flames causing severe burns.

GENERAL INFORMATION
ATLANTIC 125 - 200
DANGER
Be careful not to spill the coolant on the red-hot parts of the engine and the exhaust system: it may
catch fire and send out invisible flames.
In case any maintenance operation should be required, it is advisable to use latex gloves.
Even if toxic, coolant has a sweet flavour. Never leave it inside open containers or within the reach of
animals to prevent the risk of drinking.
KEEP AWAY FROM CHILDREN.
Do not remove the radiator plug when the engine is hot. The coolant is under pressure and could
cause severe burns.
HYDROGEN GAS AND BATTERY ELECTROLYTE
DANGER
The battery electrolyte is a toxic, caustic substance containing sulphuric acid and thus able to cause
severe burns in case of contact.
Always wear tight gloves and protective clothes when handling this fluid.
If the electrolyte gets in contact with the skin, carefully wash the parts of your body that get in contact
with the fluid with abundant fresh water.
Always use a protection for your eyes since also a very small amount of the battery fluid can cause
blindness. In the event of contact with your eyes, carefully wash them with water for fifteen minutes
and then consult immediately an eye specialist.
Should you accidentally drink some fluid, drink abundant water or milk, then drink magnesia milk or
vegetable oil and consult immediately a doctor. Battery releases explosive gases. Keep flames,
sparks, cigarettes and any other heat source away from the battery. Make sure the room is wellventilated when servicing or recharging the battery.
KEEP AWAY FROM CHILDREN.
The battery fluid is corrosive
Do not pour it on the plastic parts.
Make sure that the electrolyte acid is suitable for the type of battery used.
GENERAL PRECAUTIONS AND INFORMATION
Follow these instructions closely when repairing, disassembling or reassembling the motorcycle or its components.
DANGER
Using bare flames is strictly forbidden when working on the motorcycle. Before servicing or
inspecting the motorcycle: stop the engine and remove the key from the ignition switch; allow for the
engine and exhaust system to cool down; where possible, lift the motorcycle using adequate
equipment placed on firm and level ground. Be careful of any parts of the engine or exhaust system
which may still be hot to the touch to avoid scalds or burns.
Never put any mechanical parts or other vehicle components in your mouth when you have both
hands busy. None of the motorcycle components is edible. Some components are harmful to the
human body or toxic.
Unless expressly specified otherwise, motorcycle assemblies are refitted or re-assembled by
following the removal or disassembly procedure in the reverse order. Where a procedure is crossreferred to relevant sections in the manual, proceed sensibly to avoid disturbing any parts unless
strictly necessary. Never attempt to polish matte-finished surfaces with lapping compounds.
Never use fuel instead of solvent to clean the motorcycle.
Do not clean any rubber or plastic parts or the seat with alcohol, petrol or solvents. Clean with water
and neutral detergent.
Always disconnect the battery negative (–) lead before soldering any electrical components.
When two or more persons service the same motorcycle together, special care must be taken to avoid
personal injury.
1.3.1.
Carefully read
BEFORE DISASSEMBLING ANY COMPONENTS
•
Clean off all dirt, mud and dust and clear any foreign objects from the vehicle before disassembling any
components.
•
Use the model-specific special tools where specified.
1-6
ATLANTIC 125 - 200
GENERAL INFORMATION
DISASSEMBLING THE COMPONENTS
Never use pliers or similar tools to slacken and/or tighten nuts and bolts. Always use a suitable spanner.
Mark all connections (hoses, wiring, etc.) with their positions before disconnecting them. Identify each connection
using a distinctive symbol or convention.
Mark each part clearly to avoid confusion when refitting.
Thoroughly clean and wash any components you have removed using a detergent with low flash point.
Mated parts should always be refitted together. These parts will have seated themselves against one another in
service as a result of normal wear and tear and should never be mixed up with other similar parts on refitting.
Certain components are matched-pair parts and should always be replaced as a set.
Keep the motorcycle and its components well away from heat sources.
REASSEMBLING THE COMPONENTS
DANGER
Never reuse a circlip or snap ring. These parts must always be renewed once they have been
disturbed.
When fitting a new circlip or snap ring, take care to move the open ends apart just enough to allow
fitment to the shaft.
Make a rule to check that a newly –fitted circlip or snap ring has located fully into its groove.
Never clean a bearing with compressed air.
NOTE All bearings must rotate freely with no hardness or noise. Replace any bearings that do not meet these
requirements.
-
Use aprilia ORIGINAL SPARE PARTS only.
Use the specified lubricants and consumables.
Where possible, lubricate a part before assembly.
When tightening nuts and bolts, start with the largest or innermost nut/bolt and observe a cross pattern. Tighten
evenly in subsequent steps until achieving the specified torque.
Replace any self-locking nuts, gaskets, seals, circlips or snap rings, O-rings, split pins, bolts and screws which
have a damaged thread.
Lubricate the bearings abundantly before assembly.
Make a rule to check that all components you have fitted are correctly in place.
After repairing the motorcycle and after each service inspection, perform the preliminary checks, and then operate
the motorcycle in a private estate area or in a safe area away from traffic.
Clean all joint surfaces, oil seal edges and gaskets before assembly. Apply a light coat of lithium grease along the
edges of oil seals. Fit oil seals and bearings with the marking or serial number facing outwards (in view).
ELECTRICAL CONNECTORS
To disconnect the electrical connector, follow the procedures below. Failure to comply with these procedures may lead
to irreparable damages to the connector and the wiring as well.
If present, press the special safety hooks.
WARNING
Do not pull cables to disconnect the two connectors.
•
•
•
Grasp the two connectors and disconnect them by pulling them in the two opposite directions.
In case of dirt, rust, moisture, etc.., thoroughly clean the inside of the connectors with compressed air.
Make sure that the cables are correctly fitted inside the connectors terminals.
NOTE The two connectors have just one correct positioning. Make sure to position them in the right direction.
•
Then fit the two connectors. Make sure they are correctly coupled (if the special hooks are present, a click will be
heard).
TIGHTENING TORQUE SETTINGS
DANGER
Always remember that the tightening torque settings of all wheel, brake, wheel shaft and other
suspension parts play a fundamental role to ensure vehicle safety. Make sure that these values are
always within the specified limits.
Check fastening parts tightening torque settings at regular intervals. Upon reassembly, always use a
torque wrench.
Failure to comply with these recommendations could lead to the loosening and detachment of one of
these parts with a consequent locking of the wheel or other serious troubles affecting the vehicle
maneuverability, and thus the risk of falls and serious injuries or death..

1.3. DANGEROUS ELEMENTS
1.3.1.
WARNINGS CONCERNING FUEL, LUBRICANTS, COOLANT AND OTHER COMPONENT PARTS
DANGER
The fuel used to operate engines is highly flammable and becomes explosive under particular
conditions.
Refueling and engine service should take place in a well-ventilated area with the engine stopped. Do
not smoke when refueling or in the proximity of sources of fuel vapors. Avoid contact with bare
flames, sources of sparks or any other source which may ignite the fuel or lead to explosion.
Take care not to spill fuel out of the filler, or it may ignite when in contact with hot engine parts. In the
event of accidental fuel spillage, make sure the affected area is fully dry before starting the engine.
Fuel expands from heat and when left under direct sunlight.
Never fill the fuel tank up to the rim. Tighten the filler cap securely after each refueling.
Avoid contact with skin. Do not inhale vapors. Do not swallow fuel. Do not transfer fuel between
different containers using a hose.
DO NOT RELEASE FUEL INTO THE ENVIRONMENT.
KEEP AWAY FROM CHILDREN.
Use only premium grade unleaded petrol, min. O.N. 95 (N.O.R.M.) and 85 (N.O.M.M.).
LUBRICANTS
DANGER
A good lubrication ensures the vehicle safety.
Failure to keep the lubricants at the recommended level or the use of a non-suitable new and clean
type of lubricant can lead to the engine or gearbox seizure, thus leading to serious accidents,
personal injury or even death.
Gear oil may cause serious damage to the skin if handled daily and for long periods.
Wash your hands carefully after use.
Do not dispose of oil into the environment.
Take it to the filling station where you usually buy it or to an oil salvage center.
WARNING
When filling the vehicle with oil, take care not to spill it out since it could damage the vehicle
paintwork.
In case of contact with oil, the tyres surface will become very slippery, thus becoming a serious
danger for your safety.
In case of leaks, do not use the vehicle. Check and trace the cause of leaks and proceed to repair.
ENGINE OIL
DANGER
Prolonged or repeated contact with engine oil may cause severe skin damage.
Wash your hands thoroughly after handling engine oil.
Do not release into the environment.
Dispose of engine oil through the nearest waste oil reclamation firm or through the supplier.
Wear latex gloves during servicing.
Change engine after the first 1000 km (621 mi) and then every 6000 km (3728 mi),
1.8.1.
(Recommended) oil fork , see
2.11.2.
FRONT FORK OIL
DANGER
Modifying the suspension settings or the viscosity of the front fork oil will affect its response.
Standard oil viscosity: SAE 20 W. Choose the oil viscosity to determine the type of response required
(SAE 5W for a softer suspension, 20W for a stiffer suspension).
The two grades can also be mixed in varying solutions to obtain the desired response.
F.A. or
Fork have special properties, which enable them to retain virtually the same
viscosity regardless of temperature to give constant damping response.
(Recommended) front forks oil, see
1-8
1.8.1.
GENERAL INFORMATION
ATLANTIC 125 - 200
BRAKE FLUID
NOTE This vehicle is fitted with front and rear disc brakes. Each braking system is operated by an independent hydraulic
circuit. The information provided below applies to both braking systems.
DANGER
Do not use the vehicle in case brakes are worn out or do not work properly! The brakes are the parts
that most ensure your safety and for this reason they must always be perfectly working. Failure to
comply with these recommendations will probably lead to a crash or an accident, with a consequent
risk of personal injury or death.
A wet surface reduces brakes efficiency.
DANGER
In case of wet ground the braking distance will be doubled, since both brakes and tyres drives on the
road surface are extremely reduced by the water present on the road surface.
Any water on brakes, after washing the vehicle or driving on a wet road surface or crossing puddles
or gips, can wet brakes so as to greatly reduce their efficiency.
Failure to comply with these recommendations may lead to serious accidents, with a consequent risk
of severe personal injuries or death.
Brakes are critical safety components. Do not ride the vehicle in case brakes are not working at their
best.
Check for brakes proper operation before every trip.
Brake fluid is an irritant. Avoid contact with eyes or skin.
In the event of accidental contact, wash affected body parts thoroughly. In the event of accidental
contact with eyes, contact an eye specialist or seek medical advice.
DO NOT RELEASE BRAKE FLUID INTO THE ENVIRONMENT.
KEEP AWAY FROM CHILDREN.
When handling brake fluid, take care not to spill it onto plastic or paint-finished parts or they will
damage.
Check brake fluid level after the first 1000 Km (621 mi) and then every 6000 Km (3728 mi). See
2.10.1. and
2.10.4.; change brake fluid every two years, see
2.10.2.
Recommended) brake fluid, see
1.8.1.
DANGER
Do not use any brake fluids other than the specified type. Never mix different types of fluids to top up
level, as this will damage the braking system.
Do not use brake fluid from containers which have been kept open or in storage for long periods.
Any sudden changes in play or hardness in the brake levers are warning signs of problems with the
hydraulic circuits.
Ensure that the brake discs and friction material have not become contaminated with oil or grease.
This is particularly important after servicing or inspections.
Make sure the brake lines are not twisted or worn.
Prevent accidental water or dust from accidentally entering the circuit.
Wear latex gloves when servicing the hydraulic circuit.

GENERAL INFORMATION
ATLANTIC 125 - 200
DISC BRAKES
DANGER
The brakes are the parts that most ensure your safety and for this reason they must always be
perfectly working; check them before every trip.
A dirty disc soils the pads.
Dirty pads must be replaced, while dirty discs must be cleaned with a high-quality degreaser.
Perform the maintenance operations with half the indicated frequency if the vehicle is used in rainy or
2.1.2..
dusty areas, on uneven surfaces or on racetracks, see
2.10.3..
Check brake pads for wear, see
When the disc pads wear out, the level of the fluid decreases to automatically compensate for their
wear.
The front brake fluid reservoir is located on the right handlebar, near the front brake lever.
The rear brake fluid reservoir is located under the right fairing.
Do not use the vehicle if the braking system leaks fluid.
COOLANT
DANGER
Coolant is toxic when ingested and is an irritant, contact with eyes or skin may cause irritation.
In the event of contact with eyes, rinse repeatedly with abundant water and seek medical advice. In the
event of ingestion, induce vomiting, rinse mouth and throat with abundant water and seek medical
advice immediately.
DO NOT RELEASE INTO THE ENVIRONMENT.
KEEP AWAY FROM CHILDREN.
DANGER
Take care not to spill coolant onto hot engine parts. It may ignite and produce invisible flames. Wear
latex gloves when servicing.
Do not ride when coolant is below the minimum level.
2.9.1.. Change coolant every sixteen
Check coolant level before each ride and every 1000 km (621 mi), see
5.2.1..
months, see
Coolant mixture is a 50% solution of water and anti-freeze. This is the ideal solution for most operating temperatures and
provides good corrosion protection.
This solution is also suited to the warm season, as it is less prone to evaporative loss and will reduce the need for topups.
In addition, less water evaporation means fewer minerals salts depositing in the radiator, which helps preserve the
efficiency of the cooling system.
When temperature drops below zero degrees centigrade, check the cooling system frequently and add more anti-freeze
(up to 60% maximum) to the solution.
Use distilled water in the coolant mixture. Tap water will damage the engine.
1.8.1..
(Recommended) engine anti-freeze, see
Refer to the table below and add water with the quantity of anti-freeze to obtain a solution with the desired freezing point:

GENERAL INFORMATION
TYRES
WARNING
If tyres are excessively inflated, the vehicle will be hard and uneasy to ride, thus making you feel not
at your ease.
In addition the roadworthiness, mainly on wet surfaces and during cornering, will be impaired.
Flat tyres (insufficient pressure) can slip on the rim and make you lose the control of the vehicle.
In this case too, both vehicle roadworthiness, maneuverability and brake efficiency will be impaired.
Tyres changing, repair, maintenance and balancing must be carried out by specialized technicians
using suitable equipment.
When new, tyres can have a thin slippery protective coating. Drive carefully for the first kilometers
(miles). Never use rubber treating substances on tyres.
In particular, avoid contact with fluids/fuels, leading to a rapid wear.
In case of contact with oil or fuel, do not clean but change tyres.
DANGER
Some of the factory-assembled tyres of this vehicle are provided with wear indicators.
There are several kinds of wear indicators.
For more information on how to check the wear, contact your Dealer.
Visually check if the tyres are worn and in this case have them changed.
If a tyre deflates while driving, stop immediately.
Avoid hard brakings or moves and do not close throttles too abruptly.
Slowly close throttle grip, move to the edge of the road and make use of the engine brake to slow
down until coming to a halt.
Failure to comply with these recommendations can lead to serious accidents and consequent
personal injuries or death.
Do not install tyres with air tube on rims for tubeless tyres and vice-versa.

1.4. RUNNING-IN
1.4.1.
RUNNING-IN RECOMMENDATIONS
The running-in of the engine is essential to ensure its duration and correct functioning.
If possible, drive on hilly roads and/or roads with many bends, so that the engine, the suspensions and the brakes
undergo a more effective running-in.
During running-in, change speed.
In this way the components are first "loaded" and then "relieved" and the engine parts can thus cool down.
Even if it is important to stress the engine components during running-in, take care not to exceed.
WARNING
Only after the first 1500 km (932 mi) of running-in you can expect the best performance levels from the
vehicle.
Keep to the following indications:
•
Do not open the throttle completely if the speed is low, both during and after the running-in.

with care. Do not score or damage them.
Operate with care.
Do not damage keys and/or keyways.
When sticking decals, carefully follow the
instructions listed below.
Recommended tools:
Medium-strength spatule (1);
NOTE Soft spatules, such as those used on windshield
wipers, do not usually sufficiently remove the water
under the decal.
•
sponge or sprayer (2) with water.
NOTE Add some detergent (1-3%) to water and then
shake it to produce foam bubbles.
To apply decals, proceed as follows:
•
Position the decal (3) in upside-down position on
the work bench.
•
Keep the decal flat and pressed on the work bench
and remove the protective film (4) completely.
NOTE The use of a sprayer (2) is recommended.

decorate and position it correctly.
NOTE Press the spatule with constant movements,
working from the center towards the edge of the decal.
•
Apply a moderate pressure on the decal surface
with the spatule (1) until all the excess soap and
water under the decal itself have been completely
removed.
NOTE Do not lift the decal corners and/or edges.
•
•
Using a cloth and working from inwards to
outwards, dry the decal.
Use again the spatule. Press evenly as much as
possible. Always work starting from the center to
the outside and take special care to the corners

INTRODUCTION
To keep your vehicle in top performance conditions, aprilia strongly recommends to respect the routine maintenance
schedule for the different parts of the vehicle.
This section describes the routine maintenance operations for vehicle main components.
DANGER
Before beginning any service operations or inspection of the vehicle, switch off the engine and remove
the key, wait until the engine and the exhaust system have cooled down and, if possible, lift the vehicle
with the proper equipment onto firm and flat ground. Keep away from the red-hot parts of the engine and
of the exhaust system, in order to avoid burns. Do not hold any mechanical piece or other parts of the
vehicle with your mouth: the components are not edible and some of them are harmful or even toxic. If
not expressly indicated otherwise, for the reassembly of the units repeat the disassembly operations in
reverse order.

BLEEDING THE BRAKING SYSTEMS
Carefully read
1.2.1. and
1.3.1..
For maintenance operations schedule, see
2.1.2.
The air, if any, present inside the hydraulic circuit will serve
as “pad” by absorbing most of the pressure coming from the
brake master cylinder and thus reducing the callipers
efficiency during braking.
If some air is present inside the circuit, the brake control is
“spongy” and the braking efficiency is reduced.
DANGER
Safety critical operation. In order to avoid any
damage to both rider and vehicle, after brake
reassembly and after having restored the braking
system standard operation, make sure that all air
is bled out of the hydraulic circuit.
If the brake fluid gets in contact with the skin or
the eyes, it can cause serious irritations.
Carefully wash the parts of your body that get
in contact with the fluid. Consult a doctor or an
eye specialist if the fluid gets in contact with
your eyes.
WARNING
Handle the brake fluid with extreme care: it may
damage the vehicle paintwork and the plastic,
rubber and other parts.
In case maintenance operations are to be
performed on the hydraulic circuit, it is
advisable to use latex gloves.
When using the brake fluid, take care not to
spill it on the plastic or painted parts, since it
can damage them.
NOTE This vehicle is equipped with a braking system
consisting of:
-
a front disc brake;
a rear disc brake;
a delay valve under the instrument panel.
Through the brake line (1), the action on the right (front)
brake lever exerts a pressure on front brake calliper pistons
A and C.
Through the delay valve, the action on the left (rear) brake
lever exerts a pressure on the front brake calliper piston B

Always change a worn tyre. A tyre that
becomes punctured in the tread area should be
changed when the puncture is larger than 5
mm.
Some of the tyre types approved for this
vehicle are fitted with wear indicators.
There are various types of wear indicators.
Enquire about correct wear inspection
procedure with your supplier.
Never use tube tyres on tubeless tyre rims, or
viceversa.
Always check that the caps are in place on the
valves (1), or the tyres may deflate suddenly.
Tyre replacement and repair, and wheel
servicing
and
balancing
are
delicate
operations. They should be carried out using
adequate tools and are best left to experienced
mechanics.
The wheel must be balanced after each tyre
repair.
New tyres may be coated with an oily film.

Measure the piston jut, as shown in the figure, and
check the corresponding value.
Make sure that the starter is set to room temperature.
Jut value: 12.5 ÷ 13 mm at about 20°C
•
•
The starter will have to switch progressively off by
means of the electric heating.
Check starter resistance with the starter set to room
temperature.
Resistance: about 30 ohm
•
Using a 12 V battery, feed the automatic starter and
check that the piston reaches max. jut.
Max. jut: 18.5 ÷ 19 mm
Max. time: 5 min
•
•
Heating real time depends on room temperature.
In case of juts, resistances or times different from the
recommended ones, change the starter.
•
Fit starter to carburetor. Take care to correctly position
the OR-seal, install the knurled plate on the starter,
and tighten the two screws (1).
Aim the starter as shown in the figure.
Fit the protective cover.

ADJUSTING THE IDLING MIXTURE
The idling mixture does not need to be often adjusted.
This adjustment shall be made in full compliance with
some dispositions.
Before proceeding to carburetor adjustment, make
sure that the following conditions are respected: good
lubrication, valve clearance and timing, spark plug in
perfect conditions, sealed and clean air filter, sealed
exhaust system.
•
Connect the exhaust gas tester to the vehicle, i.e.
insert the tester copper probe into threaded pick-up
point before the silencer.
•
•
Close the secondary air inlet (1) on exhaust manifold.
Warm engine up, running it for at least five minutes at
about 2000 rpm.
NOTE It is very important that the probe be fitted before the
catalytic converter so not to take up exhaust gases already
oxidised by the catalytic converter.
NOTE The exhaust gas tester must be heated in advance
and should ensure gas reading and correct gas capacity
reset. Should these recommendations not be respected, the
reading will not be correct.
•
•
Using a duly-prepared oil filler cap, connect multimeter
thermometer to sump.
Start engine and wait for oil temperature to be between
70 ÷ 80 °C (158 ÷ 176 °F) to start idling mixture
adjustment.

FUEL SYSTEM
Using the tester rev counter or a separate rev counter,
adjust the idling screw until reaching a rpm value of
1700 ÷ 1800 g/min.
NOTE The ignition system produces a big power. In case
unsuitable rev counters are used, some reading errors may
arise. The rev counter is suitable for this operation whenever
it can take readings also at high rpm values, such as 6000 ÷
8000 rpm.
•
•
•
•
-
•
Adjust the flow screw until reaching a CO rate of 2,5 ÷
3,1%. To increase the CO rate (rich mixture) loosen
the screw, while to decrease the CO rate (lean mixture)
turn the screw in the opposite direction.
If the rpm value increases after the flow screw
adjustment, adjust the rpm value again and, if
necessary, adjust also the flow screw until reaching the
recommended values.
The idling mixture is correct when the oil temperature,
rpm and CO values are respected.
The tester gives further information, such as:
Carbon dioxide (CO2) percentage. This value is opposite
to the CO rate, namely with correct values above 12.5%.
Non-conforming values indicate that the exhaust system
is not perfectly sealed.
Unburnt hydrocarbons (HC) measured per million
(PPM). The HC value decreases as the rpm increases.
With the engine at idling speed, the standard value is
of 200 ÷ 400 PPM. These values apply to an engine
with motorcycle timing diagram. Values far above
these limits can be caused by engine misfiring due to
too a rich mixture (low CO rate), ignition defects,
improper timing or jamming or unsealed exhaust
valves.
Should some difficulties in the CO rate adjustment arise,
carefully check:
Carburetor cleaning
Automatic starter operation
Seat-tapered metering rod operation
Float chamber level adjustment.

•
•
•
•
•
7.2.1.
Remove the battery from the vehicle, see
Remove the cell caps and the breather cap.
Fill the cells with electrolyte fluid with 1.3 specific
weight.
Charge the battery at slow charge rate (that is, ampere
rating should be 1/10th of battery rating) for at least 10
hours. Refit the battery just before delivering the
vehicle to end user, that is, when vehicle is expected to
cover some distance.
Install the battery and connect the leads and the
breather hose.
To avoid degradation in the wintertime or while the
vehicle is stored away, charge the battery for 10 hours
at regular intervals (at least monthly).
Top up battery fluid level at regular intervals (at least
monthly). Top up with distilled water only.
INSPECTION
•
In the event of abnormal operation, check the charge
8.5.1.
system first, see
•
To check the battery,
•
First remove the battery from the vehicle, see
7.2.1. and proceed as follows:
Visually inspect for:
apparent signs of sulphation (one or more cells will have
become white);
check that fluid level is between the “MIN” and “MAX”
level marks;
check the outer casing for leaks.
•
Charge the battery at slow charge rate for at least 10
hours.
•
After charging, measure electrolyte fluid density in
each cell using a densimeter. Change battery when
fluid density in any one cell is less than 1.26 or when
loadless voltage is lower than 12V.
RETURN UNDER WARRANTY
The warranty is invalidated when:
the battery is damaged (dented housing, bent terminals,
etc.);
the battery is affected by extensive sulphation (normally
due to improper installation procedure and/or use).
electrolyte fluid level is too low (simply close the
breather hole with the rubber cap before shipping to
avoid this problem).

ELECTRICAL SYSTEM
SAFETY RULES
WARNING
Battery fluid contains sulphuric acid. Avoid
contact with skin and do not spill on your
clothing. Keep the battery away from sources
of heat or ignition (such as sparks). This is
especially important when the battery is under
charging, as it releases hydrogen which may
cause a fire or explosion.
