COOLING
AND
LUBRICATION SYSTEM
ENGINE
COOLANT
At the time of manufacture, the cooling system is filled with a 5050 mixture of distilled water and ethylene
-
glycol anti-freeze. This 5050 mixture will provide the optimum corrosion protection and excellent heat pro-
tection, and
will
protect the cooling system from freezing at temperatures above -31
"C
(-24
OF).
If the motorcycle is to be exposed to temperatures below -31
"C
(-24 OF), this mixing ratio should be
increased up to 55
O/O
or 60
%
according to the figure.

*
Use a high quality ethylene glycol base anti-freeze, mixed with distilled water. Do not mix an

You can be injured by scalding fluid or steam if you open the radiator cap when the engine is
hot. After the engine cools, wrap a thick cloth around cap and carefully remove the cap by
turning it a quarter turn to allow pressure to escape and then turn the cap all the way off.
*
The engine must be cool before servicing the cooling system.

Coolant is harmful;
If
it
comes in contact with skin or eyes, flush with water.
If swallowed accidentally, induce vomiting and call physician immediately.
Keep
it
away from children.
