Recommended Coolant
Pro Honda HP Coolant is a pre-mixed
solution of antifreeze and distilled water.
Concentration:
50% antifreeze and 50% distilled
water
A concentration of antifreeze below 40%
will not provide proper corrosion and cold
temperature protection.
A concentration of up to 60% will provide
better protection in colder climates.
NOTICE
Using coolant not specified for aluminum engines or
tap/mineral water can cause corrosion.
Maintenance Fundamentals
Crankcase Breather
Service more frequently when riding in rain,
at full throttle, or after the vehicle is
washed or overturned. Service if the
deposit level can be seen in the transparent
section of the drain tube.
If the drain tube overflows, the air filter
may become contaminated with engine oil
causing poor engine performance.
