Using coolant with silicate inhihitors may
cause premature wear of radiator pump
seals or blockage of radiator passages.
Using tap water may cause engine
damage.
The factory provides a 50/50 solution of
antifreeze and water in this motorcycle.
This coolant solution is recommended for
most operating temperatures and provides
good corrosion protection.
Decreasing the concentration of antifreeze
to less than 40% will not provide proper
corrosion protection.
