Checking the spark plugs

The spark plug is an important engine com-
ponent
checked, preferably by a Yamaha dealer.
Since heat and deposits will cause any spark
plug to slowly erode, the spark plugs should
be removed and checked in accordance with
the periodic maintenance chart for the emis-

of the spark plugs can reveal the condition of
the engine.
