Use an 8 oz. transparent baby bottle with a
sealable cap.
I. Set the baby bottle on a level surface and add
water
up
to
the
1.5
oz. mark. Mark
thi
s line on
the bottle with a fine-line pennanent marking pen.
This will
be
the reference line used later
in
thi
s test.

CRANKCASE BREATHER SYSTEM
(U.S.
ONLY)
To comply with air pollution standards, all
models are
eq
uipped with a closed crankcase
breather
sys
tem. The system routes
th
e engine
combustion gases into the air filter air box where
they arc burned in the engine.
I
nspt(
tion/Cleaning
Make
su
re the hose clamps at each end
of
the
breather
ho
se
(F
igure 69) arc tight. Check the hose
for
deterioration and replace
as
necessary.
Squeeze the ends
of
the air
box
drain hoses (
B,
Fig
ur
e 57)
and
drain oul all
re
sidue. This cleaning
procedure shou
ld
be done more frequently if a
considerable amount
of
riding
is
done
at
full
throttle
or
in the rain.
EVAPORATIVE EMISSION
CONTROL SYSTEM
(CALIFORNIA MODELS ONLy)
Fuel vapor from the
fuel
tank is routed through
the breather valve and into the charcoal canister.
This vapor
is
stored when the engine is
not
running. When the en
gi
ne
is
running these vapors
are drawn
from
the canister through the purge hose
and into the carburetor (Figure
70).
