COOLANT
Coolant Recommendation
The owner must properly maintain the coolant
to prevent freezing, overheating, and
corrosion. Use only high quality ethylene
glycol antifreeze containing corrosion
protection inhibitors specifically
recommended for use in aluminum engines.
(SEE ANTIFREEZE CONTAINER LABEL).
Use only low-mineral drinking water or
distilled water as a part of the antifreeze
solution. Water that is high in mineral content
or salt may be harmful to the aluminum
engine.
Using coolant with silicate inhibitors may
cause premature wear of water pump seals or
blockage of radiator passages.
Using tap water may cause engine damage.
The factory provides a 50/50 solution of
antifreeze and distilled water in this
motorcycle. This coolant solution is
recommended for most operating
temperatures and provides good corrosion
protection. A higher concentration of
antifreeze decreases the cooling system
performance and is recommended only when
additional protection against freezing is
needed. A concentration of less than 40/60
(40% antifreeze) will not provide proper
corrosion protection. During freezing
temperatures, check the cooling system
frequently and add higher concentrations of
antifreeze (up to a maximum of 60%
antifreeze) if required.
