INTRODUCTION
• This Workshop Manual describes the main electrical/mechanical checks, the essential checks and the assembly of
components supplied disassembled in order to deliver a brand new vehicle (the sequence of operations is not
binding).
• It is essential to follow the instructions with great care. Work carried out carelessly or, worse still, work that has not
been accomplished, can cause injuries and damage or, in the less serious cases, complaints.
NOTE These manuals provide the necessary information and instructions for routine maintenance and servicing.
Some information has been given to us by the engine manufacturers. We therefore decline all responsibility for any error, omission or misrepresentation.
MALAGUTI reserves the right to make any changes and modifications hereto it deems necessary
without prior notice.
MANUAL UPDATES
• The updates will be sent by us (in a reasonable time). Every CD-Rom you receive will supersede the one already in
your possession.
• The table of contents will be duly updated in the event that new pages are inserted, which render the consultation
of the manual difficult.
• IMPORTANT! The Workshop Manuals are to be considered as essential tools to be properly kept up-to-date so as
to maintain their validity over time.

SYMBOLS
• Symbols are provided for quick and easy reference (see the relevant heading), identifying situations requiring
utmost attention or providing practical suggestions or simple information.
• These symbols may appear next to a text (in which case they refer solely to the text itself), next to a figure (in
which case they refer to the topic illustrated in the figure and to the relative text), or at the top of the page (in which
case they refer to all the topics dealt with in the page).
NOTE The meaning of the symbols should be duly memorised as their scope is to avoid having to repeat
basic technical concepts or safety recommendations. They are therefore to be considered as “memory
tags”. In case of any doubt as to their meaning, consult the page in which they are fully described.

GENERAL WORK PROCEDURES
• The advice, recommendations and warnings given hereafter are aimed at ensuring maximum work safety as well
as at considerably reducing the risk of accidents, personal injury, equipment damage and idle times. We therefore
recommend observing such advice, recommendations and warnings scrupulously.
SUGGESTIONS
• Only use top quality tools and equipment.
• Only use equipment conforming to EU Directives for lifting the vehicle.
• During all operations keep tools close at hand, ideally in accordance with a predetermined sequence of use, and
anyway never leave tools on the vehicle or in concealed or hard to reach positions.
• Always keep the work area clean and tidy.
• When tightening screws or nuts, start with the larger diameter or inner fasteners, and tighten them in a “crosswise
pattern” in successive “torquing steps”.
• Preferably use open-end wrenches and tighten by exerting “pulling force” rather than “pushing force”.
• Adjustable wrenches should only be used in case of
emergency, i.e. when a properly sized wrench is not
available. During the torquing stage the movable jaw
tends to open thus risking damaging the screw head or
achieving unreliable tightening torque values. In any
case, when using an adjustable wrench, take care to
proceed as shown in the figure.
• Except in the case of occasional services, prepare a
work sheet for the customer, on which to take a note of
all the work performed and write memos relating to any
future checks that may be required.
RECOMMENDATIONS
• Before carrying out any work on the vehicle wait for all
the parts to cool down completely.
• For operations requiring two mechanics, make sure that
the various steps to be performed by each of them are
clearly defined and coordinated beforehand.
• Make sure that each component has been properly fitted before proceeding with the next one.
• Lubricate all parts (where applicable) before reinstalling them.
• Gaskets, oil seals, snap rings and cotters must be renewed at every refitting.
• The torque settings specified in the manuals refer to
the “final torque”, which must be reached progressively
by steps.
• Loosen and tighten aluminium alloy parts (covers) only
after the engine has cooled down fully.
• Only use screwdrivers of suitable sizes in relation to
the screws to be loosened or tightened.
• Work in a comfortable position and ensure that the vehicle is stable.
• Never use a screwdriver as a lever or chisel.
• Never use pliers to loosen or tighten screws or nuts because, in addition to not providing a sufficient clamping force,
they may also damage the screw head or nut hex.
• Never tap wrenches with a hammer (or other similar tools) to loosen or tighten screws and nuts.
• Never attempt to increase leverage by attaching tubes, etc. to wrenches.

INSTRUMENT
AND CONTROL FUNCTION
DRAKON 50 NKD
DIGITAL INSTRUMENT PANEL
This new digital instrument board offers several additional functions- compared to traditional ones - through which
driver may optimally manage his/her vehicle. The panel is equipped with a warning light signalling shortage of coolant
or improper connection with the radiator’s thermostat. This light comes on automatically. To select the functions shown
on the display, press the MODE button located at the front of the left hand control (see page 18).
Available functions are:
0-40 (acceleration from 0 to 40 km/h),
TIME (clock),
LAP (chronometer),
AVE (average speed),
TD (partial distance),
TOD (total distance),
BAR GRAPH with three functions: battery charge level, coolant temperature, number of engine revolutions.
For the English version, the display will be in miles, not km. The digital instrument board only works
if the battery is connected. If the battery is flat, replace it immediately. When the battery is replaced or
the fuse is removed, power is disconnected; any settings memorised on the instrument panel, except
the total distance travelled, will be reset.
Replace the flat battery with a new one; if the problem remains, call an Authorised MALAGUTI Service Centre.
Do not use your vehicle when no function appears on the display or when functions appear partially,
since the instrument board is not in the condition to provide sufficient information about your vehicle.
SETTING
Power up the instrument board by connecting the battery to the vehicle’s cables. Put the key in the ignition switch and
turn it to. The names of stored flywheels appear successively on the display: before selecting your type, check the type
of flywheel installedon your vehicle on the anti-tampering label under the seat (seepage 33). When the code of your
model appears on the display, press the MODE button, to make your selection. If you choose the wrong model, you will
be shown improper information (speed, km, etc.). If you choose the wrong model, turn the panel off, wait for about two
minutes and repeat the above operations in the correct manner.
These operations must be repeated every time the battery is disconnected.
MILES OR KILOMETRES SELECTION
If you are driving in countries with different measurement systems, you can change the unit of measurement of speed
(instant and average) and distance from kilometres to miles and vice versa. To make your selection, first of all the
vehicle must be stationary. Now hold the MODE button down for 5” after selecting the TOD function. When „Mph“ and
„Km/h“ appear, give the MODE button short presses until the unit of measurement starts flashing. Hold the MODE
button down to save your selection. The instrument board will return to its normal display mode. Any stored information
(with the exception of TOD) will be reset.
Using a unit of measurement that differs from the one used in the country where you are driving may
lead to improper calculations, especially concerning the vehicle’s speed. Consequences include exposure of the driver and others to dangers, as well as fines.

STARTING
Put the key into the ignition switch and turn it to
. A check for all operations will automatically appear for 3 seconds,
after which the last function used before turning off the vehicle will appear.
The check is automatically performed every time the key is turned to. If the check is not displayed,
contact an authorised MALAGUTI Service Centre.
CHOOSING FUNCTIONS
Functions are divided into menus and sub-menus (bar
graph), which make the display easier to understand.
To select a function, press the MODE button, as shown in
the diagram.
The diagram shows you for how long the MODE button
should be held down (near the arrows).

The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
Hydraulic brake service:
- Regularly check and, if necessary, correct the brake fluid level.
- Replace the brake hoses every four years and if cracked or damaged.
The maintenance schedule is based on average riding conditions. Machines subject to severe use or
ridden in unusually wet or dusty conditions or off the road require more frequent servicing.

REMOVING THE SPARK PLUG
• Remove the spark plug cap.
• Unscrew the spark plug (C) with the wrench provided
in the tool kit, and remove it.
C
INSPECTION
Specified spark plug: NGK BR9ES
The spark plug is an important engine component.
•
•
•
•
To service it, simply remove the plug cap and unscrew
the plug with the wrench supplied for this purposes
(take particular care if the engine is hot).
Examine the condition of the spark plug when the engine is warm, since the deposits and the colour of the
insulator provide useful information about the thermal
rating of the plug, about carburation, lubrication and
the general condition of the engine
A light tan colour of the insulator around the centre
electrode indicates that engine is correctly functioning.
If the spark plug shows a distinctly different colour, the
engine could be defective. Do not attempt to diagnose
such problems yourself. Instead have a MALAGUTI
Dealer check the vehicle.
Remove the spark plug and thoroughly clean its electrodes and insulator, using a metal brush. Adjust the
gap between the electrodes with a thickness gauge:
the gap should be 0.6 - 0.7 mm.
05189027
0,6 - 0,7 mm
•
Using spark plugs with heat rating other than
the recommended value (as marked on the
plug) can result in serious damage to the
engine.
If the spark plug insulator is cracked and/or
electrodes are corroded it must be replaced
immediately.
INSTALLING THE SPARK PLUG
• Clean the surface of the gasket. Wipe off any grime
from the spark plug threads.
• Install the spark plug with the spark plug wrench, and
then tighten it to the specified torque.
05053573
Spark plug tightening torque: 20/25 Nm (2.0/2.5 Kgm)
If a torque wrench is not available when installing a spark plug, a good estimate of the
correct torque is ¼ - ½ turn past finger tight.
However, the spark plug should be tightened
to the specified torque as soon as possible.

ADJUSTING THE CARBURETTOR
The carburettor is an important part of the engine and requires very accurate adjustments.
Therefore, most carburettor adjustments should be left to
an Authorised MALAGUTI Service Centre, who has the
necessary professional knowledge and experience.
The carburettor has been set and extensively tested
at the MALAGUTI factory. Changing these settings may
result in poor performance or damage to the engine.
ADJUSTING THE IDLING SPEED
•
•
Start the engine and warm it up for several minutes at
about 1000-2000 rpm, while occasionally revving it to
4000 to 5000 RPM. The engine is warm when it quickly
responds to the throttle.
To adjust the engine idling speed, turn the throttle stop
screw, (G). Turn the screw clockwise to increase idling
speed or counter-clockwise to decrease it.

CHECKING THE BRAKE FLUID LEVEL
If the brake liquid is insufficient, air bubbles may form in
the braking system thus impairing the effectiveness of the
brake. Before starting, make sure the brake liquid level of
the rear brake reservoir is above the minimum level mark.
As far as the front brake is concerned, the level of liquid
can be checked through the sight glass on the pump; replenish if necessary.
Observe the following precautions:
• When checking the fluid level, make sure that the reference line of the sight glass is horizontal when the
handlebar is turned.
• Use only recommended brake fluids, otherwise the
rubber seals may deteriorate, causing leakage and poor
braking performance.
• Recommended brake fluid: DOT 4
05189045
Refill with the same make of brake fluid. Mixing fluids may
result in a harmful chemical reaction and lead to poor braking performance.
When adding fluid, be careful that water does not enter
the container. Water will significantly lower the boiling point
of the fluid, and may result in vapour lock.
Brake fluid may deteriorate painted surfaces or plastic
parts. Always clean up spilled fluid immediately.

Repeat this procedure until brake fluid only flows out
of the rubber tube.
Replenish the brake fluid level in the reservoir.
While bleeding the brakes ensure that no
brake fluid comes into contact with the
scooter bodywork (risk of damage). In addition, while bleeding the brake calipers avoid
contamination of brake discs or pads with
brake fluid. Failure to comply with this prescription will have a negative effect on the
efficiency of the brake system.
If the escaping brake fluid continues to contain air bubbles during the bleed operation,
check all unions carefully: if the unions are
perfectly tight, check the gaskets on the
master cylinder and the caliper plungers for
the possible ingress of air.
When performing the bleed operation brake
fluid may leak from the bleed screw and contaminate the caliper or the disc: in this case,
dry the caliper thoroughly and degrease the
disc.
