B
CAUTION
If riding in dusty conditions, make the inspection
and replacement intervals for the air filter element
shorter; if it is found that the air filter element
is
blocked,
damaged
or
non-dustproof,
the
engine power has dramatically declined or the
fuel consumption has increased, do not solve
the problem during the next maintenance but
immediately change the air filter element. If the
engine is started when there is no air filter element,
it will wear more seriously. Check the condition
of the air filter element frequently because this
component usually has an impact on engine life.
B
CAUTION
Before installing an air filter element that has been
cleaned, apply engine oil on it or else its filtering
efficiency will be lowered and the engine life will be
shorter.
OIL COLLECTING PIPES
After the air filter is inspected,
inspect the oil collection of the oil
collecting pipes at its rear lower part.
If there is liquid in the oil collecting
pipes, drain it promptly with the
method below.
1. Loosen the clamp

.
2. Remove the oil collecting pipe

together with the
clamp

.
3. Drain all the waste liquid in the oil collecting pipe

.
4. Reinstall the oil collecting pipe

.
NOTE: Be true that reinstall the collecting pipe.
NOTE: When air is very humid, properly increase the
inspection frequency.
SPARK PLUG
Spark plug inspection
0.6–0.8mm
Measure the spark plug gap with a thickness gauge. The
standard spark plug gap is 0.6–0.8 mm. If the measured
spark plug gap is out of standard range, adjust or replace
it with a new one.
Whenever removing carbon deposits, be sure to observe
the operational color of the spark plug’s porcelain tip. This
color tells you whether or not the standard spark plug is
suitable for your type usage. A normal operating spark
plug should be very light brown in color. If the spark plug is
very white or glazed in appearance, it has been operating
much too hot. This spark plug should be replaced with a
colder plug.
