Task #23 - Engine Idle Speed

Task #24 - Radiator Coolant

The ACE has a liquid cooled engine and therefore you must maintain a proper level of radiator coolant, just like
in a car. Honda recommends that you use only Honda HP coolant or an equivalent high quality ethylene gylcol
antifreeze containing corrosion protection inhibitors specifically recommended for use in aluminum engines.
NOTICE:
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. Use only low-mineral drinking water
or distilled water as part of the anti-freeze solution.
Your ACE comes with a 50/50 solution of antifreeze and distilled water. A higher concentration of antifreeze
decreases the performance of the cooling system and is only recommended when additional protection from
freezing is needed.
A concentration of less then 40% antifreeze will not provide proper corrosion protection for your aluminum
engine. So basically, you should just keep it a 50/50 mixture or buy a pre-mixed product that is equivalent to
50/50.
Service Interval and Recommended Maintenance Manual
NOTE: Perform this task with the engine at normal
operating temperatures and the transmission in neutral.
Place the motorcycle on a level surface. Engine MUST be
warm for proper adjustment.
Hook a tachometer up to the ignition and adjust the idle
speed using the throttle stop control knob. Idle speed
should be 1000 +/- 100 rpm .
