Checking the spark plug
The spark plug is an important
engine component, which is easy to
check. Since heat and deposits will
cause any spark plug to slowly erode,
the spark plug should be removed
and checked in accordance with the
periodic maintenance and lubrication
chart. In addition, the condition of the
spark plug can reveal the condition of
the engine.
2. Remove the spark plug as
shown, with a spark plug wrench
available at a Yamaha dealer.
