TIP
Engine air filter and V-belt air filters
This model’s engine air filter is equipped with a disposable oil-coated paper element, which must not be cleaned with
compressed air to avoid damaging it.
The engine air filter element needs to be replaced and the V- belt air filter elements need to be serviced more frequent-
ly when riding in unusuall y wet or dusty areas.
Hydraulic brake service
After disassembling the brake master cylinders and calipers, always change the fluid. Regu larly check the brake fluid
levels and fill the reservoirs as required.
Every two years replace the internal components of the brake master cylinders and calipers, and change the brake fluid. Replace the brake hoses every four years and if cracked or damaged.

Checking the spark plugsThe spark plugs are important engine
components, which should be checked
periodically, preferably by a Yamaha
dealer. Since heat and deposits will
cause any spark pl
ug to slowly erode,
they should be removed and checked
in accordance with the periodic mainte-
nance and lubrication chart. In addition,
the condition of the spark plugs can re-
veal the condition of the engine.
The porcelain insulator around the cen-
ter electrode of each spark plug should
be a medium-to-light tan (the ideal color
when the vehicle is ridden normally),
and all spark plugs installed in the en-
gine should have the same color. If any
spark plug shows a distinctly different
color, the engine could be operating im-
properly. Do not attempt to diagnose
such problems yourself. Instead, have
a Yamaha dealer check the vehicle.
If a spark plug shows signs of electrode
erosion 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 thickness gauge and, if necessary,
adjusted to specification.
Clean the surface of the spark plug
gasket and its mating surface, and then
wipe off any grime from the spark plug
threads.

of the correct torque is 1/4–1/2 turn

plug should be tightened to the speci-
fied torque as soon as possible.

Engine oil and oil filter
cartridgeThe engine oil level should be checked
before each ride. In addition, the oil
must be changed and the oil filter car-
tridge replaced at the intervals speci-
fied in the periodic maintenance and
lubrication chart.
To check the engine oil level
1. Place the vehicle on the center- stand. A slight tilt to the side can
result in a false reading.
2. Start the engine, warm it up for two minutes, and then turn it off.NOTICE
ECA11291
The engine must be cold before pro-
ceeding with the oil level check, oth-
erwise the check will result in a falsereading.
3. Wait two minutes until the oil set- tles, and then check the oil level
through the check window located
at the bottom-left side of the crank-
case.
TIPThe engine oil should be between theminimum and maximum level marks.
4. If the engine oil is below the mini- mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
To change the engine oil (with or
without oil filter cartridge replace-
ment) 1. Place the vehicle on a level sur- face.
2. Start the engine, warm it up for several minutes, and then turn it1. Engine oil level check window
