COOLING SYSTEM
Radiator Hoses
Check the radiator hoses for cuts or deterioration, and the connections for
looseness and leaks.
Radiator
Check the radiator fins for obstructions (insects or mud). Remove any obstruc-
tions with a stream of low water pressure.
ATTENZIONE
If high water pressure is used the radiator fins could be damaged and impair
the radiator effectiveness.
Do not obstruct or deflect airflow through the radiator by installing unau-
thorized accessories. Any interference with the radiator airflow can lead to
engine overheating and 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 suf-
fer severe damage. Check the coolant level each day before riding the mo-
torcycle. Replenish coolant if the level is low.
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.
Coolant information
To protect the cooling system aluminum parts (engine and radiator) from rust
and corrosion, the use of corrosion and rust inhibitors chemicals in the co-
olant is essential. If rust inhibitors were not used, over a period of time the
radiator will be corroded. This will clog the tubes of the cooling system.
CAUTION
Use of incorrect coolant solutions will cause engine and cooling system
damage. Use coolant containing corrosion inhibitors made specifically for
aluminum engines and radiators in accordance with the instructions of the
manufacturer.
CAUTION
Chemical liquids are harmful to the human body. Follow manufacturer instructions.
CAUTION
Distilled water must be used with corrosion inhibitors and the antifreeze in
the cooling system. If tap water is used in the system, the cooling tubes can
be clogged and reduce the cooling system efficiency.
If the lowest ambient temperature encountered falls below the freezing point
of water, protect the cooling system. Use a permanent type of antifreeze in
the cooling system (distilled water and ethylene glycol and corrossion inhibi-
tors for aluminium engines and radiators).
For the coolant mixture ratio under extreme conditions, choose the mixture
ratio listed on the container for the lowest ambient temperature.
CAUTION
Permantent types of antifreeze have anticorrosion and anti-rust properties.
When it is diluted excessively, it loses its antifreeze and anticorrosion pro-
perties. Mix in accordance with the instructions of manufacturer.
