Emission Control Systems
Problems that May Affect Motorcycle
Emissions
If you are aware of any of the following
symptoms, have the vehicle inspected and
repaired by your Honda Motorcycle Dealer:
1. Hard starting or stalling after starting
2. Rough idle
3. Misfiring or backfiring during acceleration
4. After-burning (backfiring)
5. Poor performance (driveability) and poor
fuel economy
Federal regulations prohibit removing or
disabling a device or element of design that
may affect your engine's emission performance
unless your motorcycle will be used
exclusively in competition. If you modify your
engine for use in sanctioned competition
events, you must deface or destroy the emission
control information label.
