Replacement Parts
The emission control systems on your Honda engine were
designed, built, and certified to conform with EPA, California and
Canadian emission regulations. We recommend the use of
genuine Honda parts whenever you have maintenance done.
These original-design replacement parts are manufactured to the
same standards as the original parts, so you can be confident of
their performance. The use of replacement parts that are not of the
original design and quality may impair the effectiveness of your
emission control system.
A manufacturer of an aftermarket part assumes the responsibility
that the part will not adversely affect emission performance. The
manufacturer or rebuilder of the part must certify that use of the
part will not result in a failure of the engine to comply with
emission regulations.
Maintenance
Follow the maintenance schedule on page . 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.

Air Index

An Air Index Information hang tag/label is applied to engines
certified to an emission durability time period in accordance with
the requirements of the California Air Resources Board.
The bar graph is intended to provide you, our customer, the ability
to compare the emissions performance of available engines. The
lower the Air Index, the less pollution.
The durability description is intended to provide you with
information relating to the engine's emission durability period.
The descriptive term indicates the useful life period for the engine's
emission control system. See your Emission Control System
Warranty for additional information.
Descriptive Term Applicable to Emissions Durability Period
Moderate 50 hours [0 80 cm (0 80 cc) inclusive]
125 hours [greater than 80 cm (80 cc)]
Intermediate 125 hours [0 80 cm (0 80 cc) inclusive]
250 hours [greater than 80 cm (80 cc)]
Extended 300 hours [0 80 cm (0 80 cc) inclusive]
500 hours [greater than 80 cm (80 cc)]
1,000 hours [225 cm (225 cc) and greater]
The Air Index Information hang tag/label must remain on the
engine until it is sold. Remove the hang tag before operating the
engine.

＊ The power rating of the engine indicated in this document is the
net power output tested on a production engine for the engine
model and measured in accordance with SAE J1349 at GXV50:
7,000 rpm , GXV57: 4,800 rpm (Net Power) and at GXV50: 4,500
rpm, GXV57: 4,000 rpm (Max. Net Torque). Mass production
engines may vary from this value.
Actual power output for the engine installed in the final machine
will vary depending on numerous factors, including the
operating speed of the engine in application, environmental
conditions, maintenance, and other variables.
