Catalytic Converter
This ATV is equipped with a three-way catalytic converter.
The catalytic converter contains precious metals that serve as
catalysts, promoting chemical reactions to convert the exhaust
gasses without affecting the metals.
The catalytic converter acts on HC, CO, and NOx. A replacement unit
must be an original Honda part or its equivalent.
The catalytic converter must operate at a high temperature for the
chemical reactions to take place. It can set fire to any combustible
materials that come near it. Park your ATV away from high grasses,
dry leaves, or other flammables.
A defective catalytic converter contributes to air pollution, and can
impair your engine’s performance. Follow these guidelines to protect
your ATV’s catalytic converter.
• Always use unleaded fuel. Even a small amount of leaded fuel
can contaminate the catalyst metals, making the catalytic
converter ineffective.
• Keep the engine in good running condition.
A poorly running engine can cause the catalytic converter to
overheat causing damage to the converter or the ATV.
• If your engine is misfiring, backfiring, stalling, or otherwise not
running properly, stop riding and turn off the engine. Have your
ATV serviced as soon as possible.
