HIGH ALTITUDE RUNNING
(USA ONLY)
When operating this motorcycle at high altitude,
the air-fuel mixture becomes overly rich.
Above 6,500 feet (2,000 m), driveability and
performance may be reduced and fuel
consumption increased. The carburetor can be
modified to compensate for this high altitude
richness.
However, the carburetor must be returned to
standard factory specifications when lower
altitude riding is desired. See your authorized
Honda dealer for high altitude modification.
NOTICE
Sustained operation at altitudes below 5,000
feet (1,500 m) with high altitude carburetor
modifications may cause engine overheating
and damage.
