Inspection
The spark plug is an important
engine component and is easy to
inspect. The condition of the spark
plug can indicate the condition of the
engine.
The ideal color on the white insulator
around the center electrode is a
medium-to-light tan color for a motor-
cycle that is being ridden normally.
Do not attempt to diagnose such
problems yourself. Instead, take the
motorcycle to a Yamaha dealer. You
should periodically remove and
inspect the spark plug because heat
and deposits will cause any spark
plug to slowly break down and erode.
If electrode erosion becomes exces-
sive, or if carbon and other deposits
are excessive, you should replace
the spark plug with the specified plug.Installation
1.Measure the electrode gap with
a wire thickness gauge and, if
necessary, adjust the gap to
specification.
2.Clean the gasket surface. Wipe
off any grime from the threads.
3.Install the spark plug and tighten
it to the specified torque.
NOTE:
If a torque wrench is not available
when you are installing a spark plug,
a good estimate of the correct torque
is 1/4 to 1/2 turn past finger tight.
Have the spark plug tightened to the
specified torque as soon as possible.4.Install the spark plug cap.

seconds and stop it. While keep-
ing the motorcycle upright,
remove the dipstick (oil tank cap)
and check the oil level.

wNever remove the dipstick just
after high-speed operation. Hot oil
could spout out, causing danger.
Always wait until the oil cools
down before removing the dip-
stick.

9.Start the engine and warm it up
for a few minutes. While warming
up, check for oil leakage. If oil
leakage is found, stop the engine
immediately and check for the
cause.
10.Stop the engine and check the

sure to check the oil pressure as
described below.8 8
Remove the air bleed screw
from the oil filter cover.

Start the engine and keep it
idling until oil flows out of the
bleed hole. If no oil comes out
after one minute, turn off the
engine immediately so it will
not seize. In such a case go to
the nearest Yamaha dealer for
repairs.

After checking, tighten the air
bleed screw securely.

Carburetor adjustmentThe carburetor is a vital part of the
engine and requires very sophisticat-
ed adjustment. Most adjustments
should be left to a Yamaha dealer
who has the professional knowledge
and experience to do so. However,
the following may be serviced by the
owner as part of routine mainte-
nance.
EC000094
cCThe carburetor was set at the
Yamaha factory after many tests. If
the settings are changed, poor
engine performance and damage
may result.
