Engine oil and oil filter car-
tridge The engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the vehicle on a level sur-
face and hold it in an upright posi-
tion.NOTE:
Make sure that the vehicle is positioned
straight up when checking the oil level.
A slight tilt to the side can result in afalse reading.
2. Start the engine, warm it up until
the engine oil has reached a nor-
mal temperature of 60 °C (140 °F),
let it continue to idle for ten sec-
onds, and then turn the engine off.
NOTE:To achieve the proper engine oil tem-
perature for an accurate oil level read-
ing, the engine must have first
completely cooled down, and then
warmed up again for several minutes tonormal operating temperature.
3. Wait a few minutes until the oil set-
tles, remove the engine oil filler
cap, wipe the dipstick clean, insert
it back into the oil filler hole (with-
out screwing it in), and then re-
move it again to check the oil level.NOTE:The engine oil should be between theminimum and maximum level marks.4. If the engine oil is at or below the
minimum level mark, add sufficient
oil of the recommended type to
raise it to the correct level.
NOTE:When adding oil, be careful not to over-
fill the engine oil tank; the oil level rises
faster starting from the half level portionon the dipstick.
5. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.

Take care not to damage the follow-
ing parts:
Headlight bulb
Do not touch the glass part of
the headlight bulb to keep it free
from oil, otherwise the transpar-
ency of the glass, the luminosity
of the bulb, and the bulb life will
be adversely affected. Thor-
oughly clean off any dirt and fin-
gerprints on the headlight bulb
using a cloth moistened with al-
cohol or thinner.
Headlight lens
Do not affix any type of tinted
film or stickers to the headlight
lens.
