At the time of manufacture, the cooling system is filled with a
50:50 mixture of distilled water and ethylene glycol anti-freeze.
This 50:50 mixture will provide the optimum corrosion protection
and excellent heat protection, 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 % or 60
% according to the figure.
ICAUTION I
* Use a high quality ethylene glycol base anti-freeze,
mixed
with
distilled water. Do
not
mix
an alcohol
base anti-freeze and different brands of anti-freeze.
* Do
not
put in more than 60 % anti-freeze or less than
50 %. (Refer to Right figure.)
* Do
not
use a radiator anti-leak additive.

* 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.
