BREAK-IN
To obtain the proper operating clearances in the engine and
transmission that are necessary for smooth engine performance and
reliability, an initial break-in must be completed. For the first hour
or 100 Km of operation, run the engine at low rpm.
The slow speed necessary during the break-in period may cause
NOTE
carbon to build up on the spark plug and soil it. If inspection
of the spark plug shows this to be the case, replace the standard
spark plug with a higher heat grade spark plug for the duration
of the break-in period.
Break-in following these steps:
1. Start the engine and let it run at idle until the engine is thoroughly
warmed up.
2. Stop and let the engine cool completely
3. Start the engine and ride for 10 minutes at
moderate speed. NEVER ACCELERATE FULLY.
4. Stop and let the engine cool completely. Check and adjust chain
slack and spoke tightness and make a general inspection.
5. Start the engine and ride for 20 minutes at
moderate engine speed. NEVER ACCELERATE FULLY.
6. Stop and let the engine cool completely. Check and adjust (4).
7. Fit the inspected parts.
8. Fill the radiator up completely with cooling liquid. Before
starting the engine bleed the air from the cooling system.
9. Start the engine and ride for 30 minutes at moderate speed.
10. Stop and let the engine cool completely. Check and adjust (4).
11. After the break-in procedure has been properly carried out, the
motorcycle is ready for regular operation.
CAUTION
In any case, even an imprudent acceleration can cause engine
trouble, take special care and use the proper skills and techniques
required for correct driving of the motorcycle.
NOTE
Following the break-in, fit a new standard spark plug.

BATTERY
This battery is maintenance free and checking the fluid level is not
required. It is advisable to check the charge of the battery periodically
To remove the battery, follow these steps:
(A)
(B)
(C)
3. Disconnect the terminals ensuring that they do not
enter into contact with metal parts then extract the
battery.
WARNING
Hydrogen gas produced by the battery may explode if exposed to
open flame or sparks.
Keep the area ventilated and free from naked flames.
The operating instructions for the battery are as follows:
1. Check the battery tension in open circuit status (disconnected).
2. In case the battery's tension is below 12.60 V, or if the storage
period has exceeded 6 months, the battery has to be recharged
following the instructions in paragraph 3.
If the battery voltage is above 12.60 V, the battery can be
installed on the vehicle without having to recharge it.
3.1. Constant voltage charge mode.
- Constant voltage = 14.40 - 14.70V
- Initial charge current = 0.1 – 0.5 Cn
- Charge duration = 6 hours minimum / 24 hours maximum.
3.2. Constant power charge mode.
- Maximum charge current = 0.1 Cn
1. Remove the bolt (A) and remove the seat (B).
2. Release the rubber (C).
-16-
- Recommended charging duration = 5 - 8 hours.
- The product (charge current) X (charge duration) must be within
the range: 0.5 - 0.8 Cn.
Note
In case that a different mode of charging is used to those
established here, never exceed the maximum allowed currents
nor the maximum charge duration of 24 hours.
CAUTION
Not using the standard manner of charging may seriously shorten
the battery life.
Never exceed the standard charge.
Using a high pressure water source could damage the radiator fins
CAUTION
and render it ineffective.
Do not obstruct or deviate the radiator air intake by installing nonapproved accessories. Interfering with the radiator could cause
overheating and result in engine damage.
Coolant
This absorbs excessive heat from the engine and transfers it to the
air at the radiator. If the coolant level becomes low, the engine
overheats and may suffer severe damage. Check the coolant level
each day before riding the motorcycle. Replenish coolant if the level
is low.
Inverting the polarity of the battery terminals may cause battery
CAUTION
charge problems and cause damage to the battery system.
The red terminal is positive (+) and the black terminal is negative
(-).
THE COOLING SYSTEM
Radiator hose
Check the radiator hoses for cracks or deterioration, and connections
for leaks.
Radiator
Check the radiator fins for obstruction by insects or mud. Clean off
any obstructions with a stream of low-pressure water.
WARNING
To avoid burns, do not remove the radiator cap or try to change the
coolant when the engine is still hot. Wait for it to cool down.
Anti-freeze liquid information
To protect the cooling system aluminium parts (engine and radiator)
from rust and corrosion, the use of corrosion and rust inhibitor
chemicals in the coolant is essential. If coolant containing corrosion
and rust inhibitor chemicals is not used, over a period of time, the
radiator will rust. This will block the cooling hoses.
-17-
Use of incorrect coolant solutions will cause severe engine and
CAUTION
cooling system damage.
Use coolant containing corrosion inhibitors made specifically for
aluminium engines and radiators in accordance with the instructions
of the manufacturer.
WARNING
Coolant chemicals are harmful to the human body. Follow coolant
manufacturer warnings and coolant handing instructions.
Coolant Level
- Situate the motorcycle so that it is perpendicular to the ground.
- Remove the radiator cap in two stages. First turn the cap anti-clock
wise and wait for a few seconds. Then push and turn it further in the
same direction to remove the cap.
(A)
Soft or distilled water must be used with the inhibitor chemicals and
CAUTION
the antifreeze in the cooling system.
If normal water is used in the system, it the cooling system tubes
may become blocked.
If the lowest ambient temperature encountered falls below the freezing
point of water, protect the cooling system against freezing.
Use a permanent type of anti-freeze (soft water and ethylene glycol
plus corrosion and rust inhibitor chemicals for aluminium engines
and radiators) in the cooling system.
For the coolant mixture ratio under extreme conditions, choose the
mixture ratio listed on the container for the lowest ambient temperature.
(A). Radiator Cap.
CAUTION
Permanent types of antifreeze on the market have anticorrosion and
anti-rust properties. When diluted excessively these lose their
antifreeze and anticorrosion properties. These must be diluted in
accordance with the instructions of manufacturer.

Check the level when the engine is cold.
NOTE
Changing the coolant
- The coolant should be changed periodically to ensure long engine life.
- Wait for the engine to cool completely.
- Situate the motorcycle so that it is perpendicular to the ground.
- Remove the radiator cap.
- Place a bowl under the water pump cover and remove all the liquid
in the radiator and engine, uclock the drain screw (B). Immediately
wipe or wash off any coolant that spills on the frame, engine, or
wheels.

(2). Filler opening.
If the coolant level is low, add the correct amount of coolant through
the filler opening.
Recommended liquid
Permanent type of antifreeze (distilled water and ethylene glycol)
with corrosion and rust inhibitor chemicals for aluminium engines
and radiators).
NOTE
Initially a permanent type of antifreeze is installed in the cooling
system by the manufacturer. This is green in colour, containing
30 % ethylene glycol with a freezing point of –18°C.

(B). Screw to drain.
WARNING
If coolant gets on the tyres this will make them slippery and could
result in an accident.
-19-
- Examine the used coolant. If white cotton-like patches appear in
the liquid then this means that the aluminium elements of the cooling
system are corroded. If the liquid is brown then this means that the
steal or iron parts of the system are oxidized. In either case clean
out the system.
- Check the cooling system for damage, loose joints, or leaks.
- Put the drain screw on the water pump cover and lock it with the
indicated torque. Change the copper washer by a new one.
between electrodes using a gauge and adjust in case that it is not
correct by bending the outer electrode. If the spark plug electrodes
are oxidised, damaged or the insulation is broken then replace the
plug.
NOTE
Inspect every 30 hours. Replace every 60 hours.
Screw torque:
Drain screw on the water pump cover: 9 Nm.
- Fill the radiator up to the edge and install the radiator cap.
- Check the cooling system for leaks.
- Start the engine, warm up the engine, and then stop it.
- Check the coolant level after the engine cools down. Add
coolant up to the bottom of the radiator filler neck.
SPARK PLUG
The standard spark plug is indicated inside the table and the torque
to lock it is 13 Nm.
Standard spark plug
Standard spark plug Gap between electrodes: 0.7-0.8 mm.
The spark plug should be taken out periodically to check the electrode
gap. If the plug is oily or has carbon build up on it the clean it with
a sand blaster. Following abrasive particle cleaning, the spark plug
should be cleaned with a wire brush or similar. Measure the distance
To find the correct heat grade spark plug is being used, take it out
and examine the insulation around the electrode. If the ceramic is
light brown, the spark plug is correctly matched to engine temperature.
If the ceramic is white, the plug should be replaced with the next
coldest plug. If the ceramic is black, the plug should be replaced
with the next hottest plug.
NOTE
If the engine output decreases, replace the spark plug to regain
performance.
