This section describes the general specifications of the vehicle.
Rules
This section describes general safety rules for any maintenance operations performed on the vehicle.
Safety rules
•
Should it be necessary to keep the engine running while servicing, make sure that the area
or room is well ventilated, and use special exhaust fans, if required. never let the engine run
in an enclosed area. Exhaust fumes are toxic.
•
The battery electrolyte contains sulphuric acid. Protect your eyes, clothes and skin. Sulphuric acid is highly corrosive; in the event of contact with your eyes or skin, rinse thoroughly
with abundant water and seek immediate medical attention.
•
The battery produces hydrogen, a gas that can be highly explosive. Do not smoke and avoid
sparks or flames near the battery, especially when charging it.
•
Fuel is highly flammable, and in some conditions it can be explosive. Do not smoke in the
working area, and avoid open flames or sparks.
•
Clean the brake pads in a well ventilated environment, directing the compressed air jet so
as to not inhale the dust produced by the wear of the friction material. Even though the latter
contains no asbestos, dust inhalation is harmful.
Maintenance rules
•
Use original PIAGGIO spare parts and lubricants recommended by the Manufacturer. Nonoriginal or non-conforming spares may damage the vehicle.
•
Use only the special tools designed for this scooter.
•
Always use new gaskets, sealing rings and split pins upon reassembly.
•
After removal, clean the components using non-flammable or low fire-point solvent. Lubricate all the work surfaces except the tapered couplings before refitting.
•
After reassembly, check that all components have been installed properly and that they are
in good working order.
•
For removal, overhaul and reassembly operations use only tools provided with metric measures. Metric bolts, nuts and screws are not interchangeable with coupling members with
English measurement. Using unsuitable coupling members and tools may damage the
scooter.
•
Should any interventions to the scooter electrical system be required, check that the electrical connections - especially earth and battery connections - have been implemented
properly.

N.B.
FAILURE TO OBSERVE THE FILTERING ELEMENT CLEANING RULES MAY LEAD INCORRECT
LUBRICATION OF THE PART INVOLVED. POOR LUBRICATION COMPROMISES THE FILTERING
ELEMENT CAPACITY. EXCESSIVE LUBRICATION, AS WELL AS A DIRTY FILTER, RESULTS IN
A RICH CARBURATION.
Engine oil
In four stroke engines, the engine oil is used to lubricate the distribution elements, the bench bearings
and the thermal group. An insufficient quantity of oil can cause serious damage to the engine.
In all four stroke engines, the deterioration of the oil characteristics, or a certain consumption should
be considered normal, especially if during the run-in period. Consumption levels in particular can be
influenced by the conditions of use (e.g.: oil consumption increases when driving at "full throttle".

Check
This operation must be carried out with the engine
cold and following the procedure below:
1) Rest the vehicle on the central stand and on a flat ground.
2) Unscrew the cap/dipstick "A", dry it with a clean cloth and reinsert it, screwing it thoroughly.
3) Remove the cap/dipstick again and check that the level is between the max. and min levels; top-up,
if required.
Topping up from the MIN to MAX. level requires around 1700 cc.
If the check is carried out after the vehicle has been used, and therefore with a hot engine, the level
line will be lower; in order to carry out a correct check it is necessary to wait at least 10 minutes after
the engine has been stopped, so as to get the correct level.
Oil top up
The oil should be topped up after having checked the level and in any case by adding oil without ever
exceeding the MAX. level.
The restoration level between the MIN and MAX levels implies a quantity of oil of approx. 400 cc.

Level check
The fluid level inspection should be carried out every 6,000 km when the motor is cold, following the
methods indicated below:
•
Rest the scooter on the central stand
and on a flat ground.
•
Loosen the screw shown in the figure
and remove the expansion tank cover
located on the right side of the scooter.
•
Remove the expansion tank cap and
top up, if the fluid level is near to or below the MIN level into the expansion
tank. The fluid level should always be
between the "MIN" and "MAX." level.
•
To check the level, look into the expansion tank: the two marks into the expansion tank indicate the two levels,
"MIN" and "MAX.".
•
The coolant consists of a mixture of
50% demineralised water and ethylene
glycol and corrosion inhibitors based
anti-freeze solution.
CAUTION
DO NOT EXCEED THE MAX LEVEL WHEN FILLING SO
THAT COOLANT DOES NOT SPILL OVER THE EXPANSION TANK WHEN THE VEHICLE IS BEING USED.
N.B.
THE COOLANT CONSISTS OF A MIXTURE OF DE-IONISED
WATER AND FLUID FOR SEALED CIRCUITS. THE RESULTING MIXTURE ALLOWS A DECREASE OF THE
FREEZING POINT TO -35°C. THE MIXTURE AT A PRESSURE OF 0.9 BAR INCREASES THE BOILING POINT TO
APPROX. 125°C. THE RECOMMENDED FLUID IS ALSO
PROTECTIVE FOR ALUMINIUM ALLOYS, AND OVER TIME
THIS FEATURE MAY DECREASE. PERIODICAL REPLACEMENT IS THEREFORE ADVISABLE.

Battery recharge circuit
The recharge system is provided with a three phase alternator with permanent flywheel.
The alternator is directly connected to the voltage regulator.
This, in its turn, is connected directly to the ground and the battery positive terminal passing through
the 30A protective fuse.
This system therefore requires no connection to the key switch.
The three- phase generator provides good recharge power and at low revs, a good compromise is
achieved between generated power and idle stability.
Stator check
Checking the stator windings
WARNING
THIS CHECK-UP CAN BE MADE WITH THE STATOR PROPERLY INSTALLED.
1) Remove the door in the saddle compartment.
2) Disconnect the connector between the stator and regulator with the three yellow wires.
3) Measure the resistance between each of the yellow terminals and the other two.

Commissioning sealed batteries
If the vehicle is provided with a sealed battery, the only maintenance required is the check of its charge
and recharging, if necessary. These operations should be carried out before delivering the vehicle, and
on a six-month basis while the vehicle is stored in open circuit. Besides upon pre-delivery it is therefore
necessary to check the battery charge and recharge it, if required, before storing the scooter and afterwards every six months.
INSTRUCTIONS FOR THE RENEWAL RECHARGE AFTER OPEN-CIRCUIT STORAGE
1. Voltage check
2.
•
Before installing the battery on the vehicle, check the open circuit voltage with a regular
tester.
•
If voltage exceeds 12.60 V, the battery may be installed without any renewal recharge.

After topping-up the electrolyte level, check its density using special density gauge.
When the battery is charged, you should detect a density of 30 to 32 Bé corresponding to a specific
weight of 1.26 to 1.28 at a temperature of no lower than 15° C.
A density reading of less than 20° Bé indicates that the battery is completely flat and it must therefore
be recharged.
If the scooter is not used for a given time (1 month or more) it will be necessary to periodically recharge
the battery.
The battery runs down completely in the course of three months. When refitting the battery onto the
scooter pay attention not to invert the cables, bearing in mind that the earth (black) wire marked with
a (-) must be connected to the negative terminal whilst the other two red wires, marked with a (+) must
be attached to the positive, + terminal.
Battery recharge
WARNING
BEFORE RECHARGING THE BATTERY, REMOVE THE PLUGS OF EACH CELL. KEEP SPARKS
AND NAKED FLAMES AWAY FROM THE BATTERY WHILE RECHARGING.

Specification
Ring gear and freewheel coaxial to the flywheel.
Desc./Quantity
Intermediate gear with built-in torque limiter.
The starter system has a transmission between the motor armature and engine shaft equipped with
freewheel coaxial to the flywheel and torque limiter on the intermediate shaft.
The limiter is calibrated to 10 kgm (100 Nm); this component protects the structure of the engine and
the starter kinematic mechanism in the event of incorrect starting with consequent inverse rotations.
The freewheel is used for a sufficiently silent starting.
The starter control (energised remote control) is slaved to enabling signals by the side stand and the
emergency OFF/RUN switch, which does not allow starting given dangerous conditions.
The starter control circuit is not controlled by the immobilizer system, therefore before insisting on the
starter system, check the consensus of the immobilizer.
In order to check the enabling switches circuit, see the «Electrical system» chapter, whereas to check
the engine shaft control transmission, follow what is described in the «Flywheel and starter system»
chapter.

Inspecting the crankcase halves
- Before proceeding to check the crankcase
halves, thoroughly clean all surfaces and oil ducts.
- For the transmission-side half-crankcase, special
attention should be given to the bushings, to the
cooling jet on the transmission side (see figure)
and to the lubrication duct.
N.B.
THE JET IS FED THROUGH THE MAIN BUSHINGS. PROPER OPERATION OF THIS COMPONENT IMPROVES THE
PISTON TOP COOLING. CLOGGING HAS EFFECTS THAT
ARE DIFFICULT TO DETECT (PISTON TEMPERATURE INCREASE). FAILURE OR LEAK CAN CONSIDERABLY DECREASE THE MAIN BUSHING AND CONNECTING ROD
LUBRICATION PRESSURE.
- For the flywheel side half-crankcase, special attention should be given to the lubrication channels
for the main bearings and to the compartment and
the channels for the oil pump, as well as to the duct
for the by-pass located on the flywheel cover.
N.B.
AS ALREADY DESCRIBED IN THE "LUBRICATION" CHAPTER, IT IS ESPECIALLY IMPORTANT THAT THE BY-PASS
HOUSING ON THE FLYWHEEL COVER IS FREE FROM
WEAR THAT MAY IMPAIR THE PROPER SEALING OF THE
LUBRICATION PRESSURE ADJUSTMENT PISTON. THE
HEAD LUBRICATION CHANNEL IS EQUIPPED WITH A
SHUTTER JET; THIS GIVES A "LOW PRESSURE" HEAD
LUBRICATION. THIS CHOICE WAS MADE TO REDUCE
THE OIL TEMPERATURE IN THE SUMP.
The jet clogging impairs the head lubrication and the timing mechanisms.
A jet failure causes a decrease in the main bearing and connecting rod lubrication pressure.
- Check that the surfaces exhibit no dents or deformations, with special attention to the crankcase
coupling and the crankcase-cylinder surfaces.
- Any defects in the crankcase gasket or matching surfaces (see Flywheel cover coupling) can cause
pressurised oil leaks, thereby affecting the connecting rod and main bearing lubrication pressure.
- Check the main bearing seats that limit axial clearance in the crankshaft exhibit no wear. For the
dimensional check, refer to the instructions about checking the axial clearance and the dimensions on
the crankshaft
ENG - 145

Inspecting the crankshaft plain bearings
- To obtain a good bushing lubrication it is necessary to have both an optimal lubricating pressure
(4 bar) and a good oil flow rate; the bushings must
be correctly positioned so as not to obstruct the oil
supply channels.
- The main bushings are comprised of two halfbearings, one with holes and channels for lubrication whereas the other is solid.
- The solid half-bearing is intended to stand the thrusts caused by combustion, and for this reason it is

- To prevent obstructions in the oil feeding channels, the matching surface of the two half-bearings must
be perfectly perpendicular to the cylinder axis, as shown in the figure.
- The oil feeding channel section is also affected by the bushings driving depth compared with the
crankshaft axial clearance of the limiting surface.

General characteristics
The lubrication system is divided into two sections:
- High pressure
- Low pressure
The high pressure section includes all components located on the engine crankcase whereas the low
pressure section only refers to the thermal group.
The trochoidal pump is installed in the sump and is controlled by a pair of gears.
To guarantee the integrity of the pump, a pre-filter is fitted.
This is a screw-in type pre-filter and the relevant plug serves at the same time as an engine oil drain
plug.
ENG - 153
Engine
Beverly 500 i.e.
The pump is controlled by means of a piston by-pass calibrated to 4 bar. This is located before the
cartridge filter and both are installed on the flywheel cover, so that the seal of the filter is subject to the
pressure of the circuit.
The by-pass located before the cartridge filter improves the operating conditions for the filter, particularly
with cold oil.
The filter is equipped with an anti-drain back valve and a pressure-relief valve; the latter intervenes
when the filtering mass causes a pressure drop above 1 ± 0.2 bar.
These conditions naturally occur only with cold oil and at high engine revs or if the filter is clogged.
The filtered oil is used to lubricate the water pump shaft and once at the engine crankcase, to lubricate
the main bearings, the connecting rod head and the piston cooling nozzle, on the transmission-side
bearing.
The main bearing on the transmission side is fitted with an oil seal and the respective drain line.
The supply line for the timing system comes from the flywheel-side bearing; the supply to the head is
controlled by the respective spray jets in the engine crankcase.
The components of the timing system function with low-pressure oil lubrication.
The camshaft bearings are installed directly on the aluminium of the head; the camshaft axial clearance
is partially compensated by the oil supplied to the smaller diameter bearing.
The camshaft supplies the lubricant to the rocking levers via the holes provided; these are installed in
a position to ensure that the lubrication is maintained even after the scooter has stopped. This is achieved when the camshaft reaches its most usual and likely position when the engine is shut off.
The oil used to lubricate the head returns to the sump via the chain casing channel and therefore it also
provides lubrication for the chain.
A one-way valve and a decantation chamber are used so that gases from the crankcase do not carry
any oil. The one-way valve is a metal reed valve; the decantation chamber has a drainage hole. A failure
in these components implies oil getting into the line supplying air to the engine.
Excessive oil vapours may result in clogged ducts on the throttle body.
In order to signal low oil pressure in the system, a pressure switch is used, located immediately after
the oil filter outlet.
The lubrication circuit does not include the countershaft. The countershaft is lubricated by the oil transported by the gears or by the centrifugal effect of the crankshaft
The same applies to the piston or the pin, but in this case the cooling nozzle is particularly important.

EMS injection system
This vehicle is fitted with an integrated injection and ignition system.
Injection is indirect in the manifold through an electro-injector.
Injection and ignition are timed on the 4-stroke cycle using a tonne wheel pivoted on the camshaft control
and a reluctance variation sensor.
Combustion and ignition are managed on the basis of engine revs and throttle valve opening. Further
corrections are made according to the following parameters:
- Coolant temperature.
- Intake air temperature
- Ambient pressure
The system implements an idle feeding correction with cold engine through a Stepper motor on a bypass circuit of the throttle valve. The control unit manages the Stepper motor and the injector opening
time, thereby ensuring the idle steadiness and the proper combustion.
In all conditions of use, mixture preparation is managed by modifying the injector opening time.
The fuel supply pressure is kept constant based on the ambient pressure.
The fuel supply circuit consists of:
- Fuel pump
- Fuel filter
- Injector
- Pressure regulator
The pump, the filter and the regulator are placed inside the fuel tank on a single support.
The injector is connected by two pipes provided with quick couplings. This allows obtaining a continuous
circulation, thereby avoiding the risk of fuel boiling. The pressure regulator is situated at the end of the
circuit.
The fuel pump is controlled by the EMS control unit; this ensures the scooter safety
The ignition circuit consists of:
- HV coil
- HV cable
- Shielded cap
- EMS control unit
- Spark plug
The EMS control unit manages the ignition with optimum timing, ensuring the timing on the 4-stroke
cycle (ignition only during compression).
The EMS injection/ignition system manages the engine function according to a pre-set program.
Should any input signals fail, an acceptable working order of the engine is ensured to allow the user to
reach a service station.

Of course, this cannot happen when the rpm-timing signal is missing, or when the failure involves the
control circuits:
- Fuel pump
- HV coil
- Injector
The control unit is provided with a self-diagnosis
system connected to an indicator light in the instrument panel.
Failures are detected and restored by the diagnostic tester.
In any case, when the fault is no longer present,
the data storage is automatically cleared after 16
cycles of use (cold start, running at regular engine
temperature, stop).
The diagnostic tester is also required to adjust the
idle mixture.

The ignition system control unit is programmed to ensure optimal carburetion while riding along streets.
The idle carburetion needs to be adjusted to compensate for the production tolerances and engine
settlement.
This adjustment is done by modifying the injector opening time with the engine running at idle.
To adjust, proceed as follows:
1 - Idle carburetion adjustment must be performed on an engine ready for precision adjustment.

WHEN THE CO PERCENTAGE IS RIGHT AND THE CO2 PERCENTAGE DOES NOT FALL INTO
THE SPECIFIED VALUES, THE LAMBDA VALUE IS ALSO DISTORTED.
If this occurs, carefully check the exhaust system for adequate sealing.
When the CO percentage is correct and the HC (PPM) value exceeds the maximum limit allowed, check:

- valve clearance
- timing system phase
- outlet valves for sealing
When the control unit is replaced, reset TPS and pre-program the trimmer value of the original control
unit (if available) preventively.
In any case, check the CO value again.
Make sure the entire exhaust system is sealed.
Remove the intake cap on the exhaust pipe, connect the dissipater and the extension pipe.
Warm-up the engine and use an exhaust analyser to check the carburation of the idle speed, if necessary, restore the correct setting using a scooter Tester, see «Adjusting idle carburation».

Precautions
1. Before fixing any part of the injection system, check to see if there are any registered faults. Do not
disconnect the battery before checking for faults.
2. The fuel supply system is pressurised at 300 kPa (3 BAR). Before disconnecting the quick coupler
of a pipe in the fuel supply system, check that there are no naked flames. Do not smoke. Act with caution
to prevent spraying in the eyes.
3. When fixing electric components, operate with the battery connected only when actually required.
4. When functional checks are performed, check that the battery voltage is over 12V.
5. Before trying to start up, check to make sure there is at least two litres of fuel in the tank. Failure to
respect this norm will damage the fuel pump.
6. If the scooter is expected to remain unused for a long time, refill the tank up to a little over half the
level. This will ensure the pump will be covered by fuel.
7. When washing the vehicle, be careful with the electric components and wiring.
8. When an ignition fault is detected, start the checks from the battery and the injection system connections.
9. Before disconnecting the EMS control unit connector, perform the following operations in the following
order:
- Set the switch to «OFF»
- Disconnect the battery
Failure to respect this norm may damage the control unit.
10. Do not invert the polarity when fitting the battery.
11. In order to prevent damages, disconnect and reconnect the EMS connectors only if actually required.
Before reconnecting, check that the connectors are dry.
12. When carrying out electric inspections, do not force the tester probes into the connectors. Do not
take measurements not specifically foreseen by the manual.
13. At the end of every check performed with the diagnostic tester, protect the system connector with
its cap. Failure to respect this norm may damage the EMS control unit.
14. Before reconnecting the quick couplers of the power supply system, check that the terminals are
perfectly clean.

The injection ECU manages the negative of the light. The light must go off after the initial check. The
light goes on again when the ECU self-diagnosis detects a fault. When the fault disappears the light
goes back off, however, the related operating tests need to be carried out. The light can go on whether
the engine is able to run or not.
Self-diagnosis system
The injection control unit is provided with an auto-diagnosis function.
When a failure is detected, the control unit:
- turns on the injection telltale light (only when it is current).
- enables the engine management check according to the data entered in the control unit (where possible).
- stores the failure (always).
In the event of intermittent failures, the indicator follows the failure trend and storage remains active.
Stored data are automatically deleted when the failure does not occur for over 16 usage cycles of the
scooter (heating - use - cooling). The battery disconnection does not delete stored data.
INJEC - 188

Checking stored failures
Connect the diagnostic tester to the scooter system.
Select the function "ERROR" in the menu.
Specific tooling
020680Y Diagnosis Tool
The tester pages display the list of errors detectable by the auto-diagnosis.
Errors detected by the auto-diagnosis are marked
by one or two reference dots.
They are arranged on two lines:
Line A = current failures (present)
Line M = stored failures
Errors detectable by the auto-diagnosis may refer to the following system circuits or sectors of the
control unit:
- Throttle valve position signal
- ambient pressure signal
- coolant temperature signal
- intake air temperature signal
- wrong battery voltage
- Injector and relevant circuit
- HV coil and relevant circuit
- Stepper and relevant circuit
- Pump relay circuit
- Electric fan relay circuit
- RAM memory
- ROM memory
- EEPROM
- Microprocessor
- Signals panel (stroke - revolution signal - unsteady cycle)
Underlined failures cause the engine to stop.
In the other cases, the engine works managed by the basic data.

Fuel supply system
Fuel is fed to the injector by a pump, a filter and a
pressure regulator integrated with the fuel level indicator inside the tank.
The pump unit is connected to the injector by:
2 semi-flexible pipes
4 quick unions
1 T union with O-ring and retain bracket for the injector
The pipes are crossed and fixed to the intake manifold to prevent wear of the quick unions connected
to the T union for the injector.
N.B.
BEFORE WORKING ON THE FUEL SUPPLY SYSTEM, CAREFULLY CLEAN THE PARTS TO
PREVENT DAMAGING THE FAST-RELEASE COUPLING SEAL OR TO PREVENT DIRT GETTING
INTO THE DUCTS.
CAUTION
THE SYSTEM IS UNDER PRESSURE.
DO NOT SMOKE DURING ANY OPERATION.
PREVENT ANY FUEL SPRAYING.
WARNING
- BEFORE STARTING THE ENGINE, CHECK WHETHER THERE IS FUEL IN THE TANK.
- DO NOT USE THE SCOOTER IN RESERVE FOR A LONG TIME, UP TO THE POSSIBILITY OF
RUNNING OUT OF FUEL.
- IF THE SCOOTER IS EXPECTED TO REMAIN UNUSED FOR A LONG TIME, REFILL THE TANK
AT LEAST TO HALF THE LEVEL.
FAILURE TO OBSERVE THESE RULES CAN DAMAGE THE PUMP.

Pump supply circuit
The control unit starts the pump in the following conditions:
- by setting the switch to «ON» with the emergency switch to «RUN» and side stand raised. The pump
does not supply.
- If the rpm-timing signal is received. Continuous supply.
The initial timing is useful to bleed the system especially after a stop with engine in temperature. In
these conditions, the fuel altered by boiling will be mixed with that in the tank.
During use, the pump operation will be subject to the engine speed.

This section describes the operations to be carried out to perform electric checks on the pump.
Resistor check
Disconnect the connector from the pump support.
Using a tester, measure the pump winding resistance.
Connect the tester probes to the pump support
pins as shown in the figure.
Electric characteristic
Resistance:
approx. 1.5 Ω
In case of infinite resistance, replace the pump.
With infinite resistance, the pump does not rotate.
With resistance close to 0 Ω, the pump power consumption is too high, with the possibility of blowing
the 10 A fuse No. 2. Perform the following check.
INJEC - 203
Injection
Beverly 500 i.e.
Pump consumption check
The pump power consumption may vary according
to:
- Power supply voltage
- Pump running-in
- Regulation pressure
- Delivery filter cleaning
To check the current consumption, proceed as follows
- Disconnect the pump remote control switch connector.
- With key switch set to "OFF", connect the jumpers 30-87 on the connector using the tester probes
in ammeter function (see figure).
- Check the pump rotation and power consumption
N.B.
THIS CONSUMPTION REFERS TO:
- POWER SUPPLY VOLTAGE = approx. 12 V
- PUMP RUN IN
- SYSTEM PRESSURE = 300 kPa (3 BAR)
- FUEL FILTER CLEAN
Electric characteristic
Current consumption:
approx. 3.5 - 4.2 A
A dirty filter causes an increase of input. If the pressure-relief valve opens, the pump absorbs approx.
6-7A.
In case of excessive input (5A), replace the filter. See pump support overhaul.
If the fault continues, replace the pump.
Fuel filter check
To check the fuel filter inspect the following:
- Free flow
- Current consumed by the pump. A clogged filter causes:
- Poor performance especially at full power
- Pump input increase
N.B.
DO NOT BLOW THE FILTER WITH COMPRESSED AIR. A DAMAGED FILTER MAY CAUSE THE
INJECTOR CLOGGING.

Once the system has been programmed, master key transponder, decoder and control unit are strictly
matched.
With this link established, it is now possible to encode new service keys, in the event of losses, replacements, etc.
Each new programming deletes the previous one so, in order to add or eliminate keys, you must repeat
the procedure using all the keys you intend to keep using.
N.B.
AN ACCIDENTAL LOSS OF THE SERVICE KEY PROGRAMMING CAN ARISE FROM GENERAL
FAULTS OF THE IGNITION SYSTEM. IN THIS CASE, CHECK THE HV LINE SHIELDING.
In any case it is advisable to use resistive spark plugs.
LED signals
When the key switch is set to "ON" and programming is performed normally, the LED switches on
as shown in the figure.
WITH MASTER KEY
After the confirmation flash when switching to
"ON", a number of flashes are emitted, equal to the
number of keys used for programming.

WITH SERVICE KEYS
Deterring blink
Switching from «ON» to «OFF» with programmed
system causes the intermittent switching on of the
LED, with an antitheft effect.
This occurs with any key used for programming.
If the scooter is not used, the deterrent light stops automatically after 48 hours to prevent discharging
the battery. A new 48-h cycle starts by switching from "OFF" to "ON" and "OFF" again.
Checking master-box data

The sensor allows the rotations and the angular position of the crankshaft to be recognised by reference
to the TDC. Since the wheel speed sensor is pivoted on the camshaft it is also possible to recognise

the 4-stroke cycle. Such solution allows controlling the injector and the spark plug every two revolutions
of the crankshaft.
The sensor is of the reluctance variation type and is therefore comparable to an alternate current generator that powers the control unit.
The signal frequency is interrupted by the vacuum generated by the two missing teeth on the wheel
speed sensor.
The sensor signal is fundamental for obtaining starting of the engine.
The ECU self-diagnosis is enabled on this circuit in 2 different ways based on use conditions.
Right after turning to «ON» (Power under the panel present in the CPU), the continuity and isolation of
the sensor and related circuit are checked.
Any faults discovered in this phase are signalled via the injection telltale light.
The fault continues to be signalled, but the circuit is only checked when turning to "ON". Therefore faults
which occur or disappear after turning to "ON" are not acknowledged.
During and after the start phase, the self-diagnosis checks the alternating current produced by the
sensor (synchronisation of the signal panel).
INJEC - 225
Injection
Beverly 500 i.e.
If a signal panel is detected which is not perfectly synchronised, corrective interventions are applied
used to reconstruct the cycle. In this case the self-diagnosis records the number of lost synchronisations
and signals the fault via the injection telltale light.
The light remains on during the period the cycle is reconstructed.
If the rpm-timing signal is completely missing due to mechanical faults or lack of magnetic activity, it
will be impossible to start the engine (or it will stop while driving) and the self-diagnosis will not be able
to record any faults.

The ignition system is integrated with the injection
and it is a high-efficiency inductive type ignition.
The control unit manages two important parameters:
- Ignition advance
This is optimised according to the engine rpm, to
the engine load, temperature and ambient pressure
With idle engine, it is optimised to obtain the stabilisation of the speed at 1450 ± 50 R/1'. - Magnetisation time
The coil magnetisation time is controlled by the
control unit. The ignition power is increased during
the engine start-up.
The injection system recognises the 4-stroke cycle
and therefore, ignition is only controlled during
compression.

The coolant temperature sensor is installed on the engine head and provides the indications for the
digital instrument and for the injection.
It is realised with two electrically different sections.
The injection section is realised with an NTC sensor connected to a 5V powered circuit. The resistance
variation causes a variation of the circuit voltage. Such voltage is combined with a temperature value.
By this value, the control unit can manage the engine operation, optimising it for all temperatures.
A failure of this circuit causes the switching on of the injection telltale light and the tripping of the safeties
(among which the electric fan continuous start). In these conditions, the engine works, even though not
in an optimum way, always safeguarding the catalytic converter integrity.
A false temperature value that falls within the range of possible temperatures is a failure very difficult
to manage. This can cause a failure of the safeties and an improper management of the ignition. Such
failure is more easily detected upon the engine start-up.
To check the sensor and related circuit, proceed as follows:

The throttle valve position sensor is not removable
and is installed on the throttle body.
This sensor receives a 5-V power supply from the
control unit and transmit a gradually increasing
voltage to the same, with an increase of the throttle
valve opening. The control unit converts this voltage at an angular position of the valve.
The engine rpm and the throttle valve position are
the two basic signals for the engine management.
A failure of this circuit causes the switching on of
the injection telltale light and the tripping of the
safeties. In these conditions, the engine works,

even though not in an optimum way, always safeguarding the catalytic converter integrity.
The throttle valve position signal is especially important at the small valve openings. These areas
are also where the sensor works more frequently,
and therefore they require more frequent checks
after a high number of kilometres run.

Zeroing the throttle
Resetting the throttle valve position signal (TPS reset)
The throttle body is supplied with throttle valve position sensor and is pre-calibrated.
Pre-calibration entails regulating the minimum opening of the throttle valve to obtain a certain flow of
air under pre-set reference conditions.
Pre-calibration ensures optimal air flow to control idling.
This regulation must not be tampered with in any way whatsoever.
The injection system will complete the management of the idling through the Stepper motor and the
variation of the ignition advance.
The throttle body after the pre-calibration has an opened valve with an angle that can vary depending
on the tolerances of the machining of the pipe and the valve itself.
The valve position sensor can also assume various fitting positions. For these reasons the mV of the
sensor with the valve at idle can vary from one throttle body to another.
To obtain the optimum fuel mixture, especially at small openings of the throttle valve, it is essential to
match the throttle body with the control unit following the procedure known as TPS resetting.
With this operation we inform the control unit, as the starting point, of the mV value corresponding to
the pre-calibrated position. The control unit will recognise such value as angle 5.24°.
To reset, proceed as follows:

Reset should be performed in the following cases:
- on first fitting.
- in case of replacement of the throttle body
- if the injection control unit is replaced.

Specification
Electronic control unit
Stepper motor
The throttle body is provided with an auxiliary air
circuit. This is enabled by a piston valve controlled
by a Stepper motor.
The Stepper is powered by the control unit only
when the opening must be changed.
The revolution is divided into portions called
"steps".
By changing the opening "steps" it is possible to
properly feed the engine to facilitate the start-up
procedure and adjust the air feeding with cold engine. When the engine reaches the working temperature, the Stepper partly closes again.
INJEC - 254

Stepper motor
Beverly 500 i.e.
Injection
To prevent wear of the adjustment piston, operation at full speed is obtained with a minimum opening of 43 - 45 "steps".
To recover possible adjustments, every switching
to "OFF" causes the piston to close up to end of
travel and to open up again by a fixed number of
steps (self-reset).
When the control unit changes the Stepper opening "steps" it also changes the injection time to
ensure proper ignition.
The engine idle speed is practically stabilised at
1550-50 rpm. After a hot start-up step you can
perceive the first increase in the revolutions and
the subsequent closing of the Stepper to stabilise
the speed.
In case of irregular speed, before carrying out
electric checks inspect the throttle valve and the
auxiliary air circuit cleaning.
To check the Stepper and the relevant circuit, proceed as follows:
1 - Connect the diagnostic tester.
Set the switch to "ON" with switch to "RUN" and
side stand raised.
Lift the scooter on the central stand. Select the
function "ERRORS" in the menu.

INDEX OF TOPICS
COOLING SYSTEM
COOL SYS
Cooling system
Beverly 500 i.e.
Circuit diagram
The cooling system is a forced circulation type system, with continuous venting and air pressurisation.
Circulation takes places by a centrifugal pump driven by the countershaft.
The pump delivers the coolant to the thermal group.
The two-way thermostat support is connected in output to the head. One way is connected to the pump
and the other to the radiator (of the horizontal circulation type).
The radiator output is directly connected to the pump.
The expansion tank is connected in parallel to the radiator.
The radiator hot box is connected to the upper side of the expansion tank (in air).
The radiator cold box is connected to the lower side of the expansion tank (in the fluid).
When the engine is cold, the thermostat output to the radiator is closed, even though there is still a little
flow for de-aeration obtained by a hole into the closing plate.
In this case, the circulation into the thermal group is active to ensure an even heating.
Once the working temperature has been reached, the main circulation on radiator and expansion tank
starts.
With the small openings in the thermostat there is a flow overlapping (recirculation and main one).
When the temperature is higher, the thermostat allows excluding the recirculation to favour the main
circulation.
In this case, the flow is consistent in the expansion tank as well, and this ensures a continuous automatic
venting.
COOL SYS - 302
Beverly 500 i.e.
Cooling system
For the system venting during the circuit filling step, there is a special union at the top of the head (see
filling rules).
To ensure cooling in case of poor dynamic ventilation, there is an electric fan controlled by the injection
system.

Water pump ceramic seal
Our Leader, Quasar, and Master liquid cooled engines are equipped with water pumps fitted with the
ceramic seal in the subject. This component is intended to guarantee the leak tightness of the coolant
in relation to the pump shaft. The seal achieved via two special ceramics, a static one and a spinning
one, kept in contact by the thrust of a spring, coaxially mounted onto the pump shaft. The efficiency of
this system is guaranteed by the accurate machining and cleaning of the components as they are fitted;
in any case, ceramic seals are subjected to a running in period. During this period (1,000 ± 1,500 km),
there may be small leaks through draining holes, which remain visible on the aluminium crankcase.
This phenomenon is particularly visible there where the hole is more exposed (Quasar and Master). In
such cases we recommend cleaning the casing in order to be able to check again for leaks after a
distance of more than 1500 km. If leaks continue or in the event of real losses, the ceramic seal should
be replaced. For these operations, observe the tools and instructions given in the relevant service
station manuals.
Note: The ceramic seal may be overhauled according to the following couplings:
•
Coupling "A": seal ring no. 485084 with ceramic seal no. 486216
•
Coupling "B": seal ring no. 841329 with ceramic seal no. 841330
The couplings above may be selected according to their availability, as they are interchangeable.
