High Altitude Carburetor Adjustment
Technical Information
Sustained operation at altitudes below
5,000 f eet (1,500 m) with high altitude
carburetor modif ications may cause engine
overheating and damage.
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 Honda
dealer for high altitude modification.
