High
altitude operation
At
high altitude, the standard carburetor
air-fuel mixture wilI
be ex-
cessively rich.
Performance
will
decrease.
and fuel consumption
will
increase.
High altitude performance can be improved by specific
modifica-
tions to
the carburetor.
lf
you
always operate
the
engine
at
altitudes higher than
1,830
m
(6,000
feet) above sea
level,
have
your authorized Honda dealer perform these carburetor modifi-
cations.
Even
with
suitable carburetor
jetting, engine horsepower will
decrease
approximately
35% for
each 305 m
(1,000
feet) increase
in
altitude. The
affect of altitude on
horsepower
will
be greater
than
this if
no
carburetor modification
is made.
CAUTION:
Operation
of
the engine at
an
altitude lower
than the carburetor
is
letted
for
may result
in
reduced performance, overheating,
and
serious engine damage caused
by an
excessively
lean airlfuel
mixture.
