EBU35121Checking the spark plugsThe spark plug is an important engine com-
ponent which should be periodically
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-
sion control system. In addition, the condition
of the spark plugs can reveal the condition of
the engine. The porcelain insulator around the center
electrode of each spark plug should be a me-
dium-to-light tan color (the ideal color when
the vehicle is ridden normally), and all spark
plugs installed in the engine should have a
similar color. If any spark plug shows a dis-
tinctly different color, the engine could be op-
erating improperly. Do not attempt to
diagnose such problems yourself. Instead,
have a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode ero-
sion and excessive carbon or other deposits,
it should be replaced.
Before installing a spark plug, the spark plug
gap should be measured with a wire thick-
ness gauge and, if necessary, adjusted to
specification.1. Rear axle boot

EBU35141Cleaning the spark arrester
WARNING
EWB03370Hot exhaust system may cause burns. To
avoid burns or fires, make sure that the en-
gine is stopped and the exhaust system is
cool before cleaning the spark arrester. Do
not start the engine while cleaning the ex-
haust system. 1. Remove the tailpipe cover by removingthe tailpipe cover bolts. 2. Remove the tailpipe bolts.
3. Remove the tailpipe by pulling it out of
the muffler, and then remove the gasket.
4. Tap the tailpipe lightly, and then use a wire brush to remove any carbon depos-
its from the spark arrester portion of the
tailpipe and inside of the tailpipe housing.1. Tailpipe cover

EBU36620Brake light switchThe brake light, which is activated by the
brake pedal, should come on just before
braking takes effect. Since the brake light
switch is a component of the YCC-S system,
it must be adjusted by a Yamaha dealer, who
has the necessary professional knowledge
and experience.EBU35930Cable inspection and lubrication
WARNING
EWB03380Damaged cables could restrict operation,
which may cause an accident or injury. In-
spect control cables frequently and re-
place damaged cables. Corrosion can
result when the outer covering of control
cables becomes damaged. Cables can
also become frayed or kinked.
Lubricate the cable ends. If the cables do not
operate smoothly, ask a Yamaha dealer to re-
place them.EBU36760Pedal lubricationThe pivoting parts of the brake and accelera-
tor pedals should be lubricated periodically to
prevent rust and ensure smooth operation.Recommended lubricant:Yamalube LubezAll (synthetic lubricant spray with PTFE)
