Do not add any chemical additives to
the engine oil. The engine oil also
lubricates the clutch and any additives
could cause the clutch to slip.
Do not use mineral, vegetable, non-
detergent oil, castor based oils or any oil
not
conforming
to
the
required
specification. The use of these oils may
cause instant, severe engine damage.
Ensure no foreign matter enters the
crankcase during an engine oil change
or top off.
Cooling System
To ensure efficient engine cooling, check
the coolant level each day before riding
the motorcycle, and top off the coolant
if the level is low.
Note:
•
A year round, Hybrid Organic Acid
Technology (known as Hybrid OAT
or HOAT) coolant is installed in the
cooling
system
when
the
motorcycle leaves the factory. It is
colored green, contains a 50%
solution of ethylene glycol based
antifreeze, and has a freezing point
of -35°C (-31°F).
Corrosion Inhibitors
To protect the cooling system from
corrosion, the use of corrosion inhibitor
chemicals in the coolant is essential.
If coolant containing a corrosion
inhibitor is not used, the cooling system
will accumulate rust and scale in the
water jacket and radiator. This will block
the coolant passages, and considerably
reduce the efficiency of the cooling
system.
Warning
HD4X Hybrid OAT coolant contains
corrosion inhibitors and antifreeze
suitable for aluminum engines and
radiators. Always use the coolant in
accordance with the instructions of
the manufacturer.
