6 break down and erode. If electrode
erosion becomes excessive, or if
carbon and other deposits are
excessive, you should replace the
spark plug with the specified plug.
Before installing the spark plug,
measure the electrode gap with a
wire thickness gauge; adjust the
gap to specification as necessary.
When installing the plug, always
clean the gasket surface and use a
new gasket. Wipe off any grime
from the threads and tighten the
spark plug to the specified torque.Specified spark plug:
DR8EA (NGK) or
X24ESR-U (DENSO)Spark plug gap:
0.6 ~ 0.7 mm
Tightening torque:
Spark plug:
17.5 Nm (1.75 m0kg)
NOTE:
If a torque wrench is not available
when you are installing a spark
plug, a good estimate of the cor-
rect torque is 1/4 to 1/2 turn past
finger tight. Have the spark plug
tightened to the specified torque as
soon as possible.EAU00517Engine oil

a. Place the motorcycle on a level
place and hold it in an upright
position. Warm up the engine

check the oil level through the
level window located at the
lower part of the right side
crankcase cover.
NOTE:
Wait a few minutes until the oil
level settles before checking.
c. The oil level should be
between the maximum and
minimum marks. If the level is
low, add sufficient oil to raise
it to the proper level.
