Spark Plug
After the first 1,000 km or every 5,000 km, clean the carbon deposit attached to
the spark plug with a small metal brush or cleaner. Readjust the spark plug gap
with a gap gauge so as to keep it between 0.6 and 0.8 mm. Replace the plug with
a new one after every 10,000 km.
While cleaning the carbon deposit, observe the color of the porcelain tip. The
color can tell you if the standard spark plug apply to your motorcycle. In case of
being wet or black in color, it is more suitable to use high-pressure hot type of
spark plug. The normally worked spark plug usually is light gray or light brown.
If the spark plug is white or seem flashing, it shows that the spark plug works
under the overheat condition. In such case, change the spark plug with a cold
type one.
CAUTION
The standard spark plug available to this type of motorcycle is carefully chosen to suit most of the working
scope. If the color of spark plug is different from the standard one, consult with dealers before changing other
types of spark plugs of different heat-resisting range. Improper spark plug will lead to serious damage to the
engine. Choosing improper spark plugs can make operation very difficult. So contact with your dealer before
using other kinds of spark plugs.
