MAINTENANCE & ADJUSTMENTS
Emission Control System Source of emissions \ The combustion process produces carbon monoxide, oxides of
nitrogen, and hydrocarbons. Control of hydrocarbons and oxides
of nitrogen is very important because, under certain conditions,
they react to form photochemical smog. Carbon monoxide is an
odorless, colorless gas which is poisonous. While it does not
contribute directly to the formation of smog, it is deadly.
American Honda Motor Co., Inc. uses lean carburetor settings
and other systems to reduce the emissions of carbon monoxide,
oxides of nitrogen, and hydrocarbons.
Proper Maintenance is the Owner’s Responsibility Replacement parts
Honda recommends only the use of new, genuine Honda parts
or their equivalent. The use of other replacement parts which are
not of equivalent quality may impair the effectiveness of your
emission control system.
Maintenance
Follow the maintenance schedule on page 39. Remember that
this schedule is based on the assumption that your machine will
be used for its designed purpose. Sustained high-load or
high-temperature operation, or use in unusually wet or dusty
conditions, will require more frequent service.
