Inspection and Maintenance

Caution
Don’t over tighten the spark plug or cross thread it. In order not to damage
the cylinder head, do not allow the contamination to enter the engine
through spark plug hole.
The standard spark plug for this scooter has been carefully selected to meet
the vast majority of all operation ranges. If the spark plug colour indicates
that other than standard spark plug should be used, it is best to consult the
dealer before selecting an alternate plug or heat range. The selection of an
improper spark plug can lead to severe engine damage.
Fuel Hose
Replace the fuel hoses every two years.
Air Filter
The air filter element used in this scooter is a paper element type with
a foam outer jacket. If the filter element has become clogged with dust,
intake resistance will increase with a resultant decrease in power
output and increase in fuel consumption due to the richer mixture.
Check and clean the air filter element according to the following
procedure.
1. Remove the screws.
2. Remove the two fixing slippers by sliding them rearward.
3. Remove the air filter cover.
4. Remove the filter element.
5. Clean the filter element by blowing it through with compressed air.
Clean every 1000 KMs and replace every 6000 KMs
Caution
1. Before and during the cleaning operation, carefully examine the air filter
element for any tears in the material. A torn filter element must be replaced
with a new one.
2.If driving under dusty conditions, the filter element must be cleaned
more frequently.
3. NEVER OPERATE ENGINE WITHOUT THE FILTER ELEMENT.
4.
Always be sure that the filter element is in excellent
operational condition at all times. The life of the engine depends largely
on this very important individual component.
