Catalytic Converters - Honda Goldwing GL1800 Owner's Manual

This motorcycle is equipped with a two three-way catalytic converters.
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 motorcycle away from high grasses, dry leaves, or other
flammables.
Defective catalytic converters contribute to air pollution, and can impair your
engine's performance. Follow these guidelines to protect your motorcycle's

catalytic converters.

Always use unleaded gasoline. Even a small amount of leaded gasoline can
contaminate the catalyst metals, making the catalytic converters ineffective.
Keep the engine tuned-up.
Have your motorcycle diagnosed and repaired if it is misfiring, backfiring,
stalling or otherwise not running properly.
