spark plug. A normal working spark plug shall be light gray or cotton yellow. If
not, please consult your dealer at the first opportunity
The standard spark plug for the motorcycle has been carefully selected and is
suitable for most operations. If the color of the spark plug is found to be
different from normal, it is advisable to contact your distributor before replacing
with a spark plug in a different heat resisting range. An improper spark plug may
cause serious damage to the engine. Therefore, consult with your distributor
before selecting another brand of spark plug.

The Spark plug should not be over tightened otherwise the threads of the
cylinder head may be damaged. When the spark plug is out, avoid any
