To install the spark plu
g
1. Clean the surface of the spark
plug gasket and its mating sur-
face, and then wipe off any grime
from the spark plug threads.
2. Install the spark plug with the
spark plug wrench, and then tight-
en it to the specified torque.
TIP
If a torque wrench is not available
when installing a spark plug, a good
estimate of the correct torque is 1/4–

spark plug should be tightened to the
specified torque as soon as possible.
3. Install the spark plug cap.

The transmission must be checked for
oil leakage before each ride. If any

several minutes, and then turn it
off.
2. Place the motorcycle on a level
surface and hold it in an upright
position.
3. Place an oil pan under the trans-
mission case to collect the used
oil.
4. Remove the oil filler cap, the trans-
mission oil drain bolt and its gas-
ket to drain the oil from the
transmission.
5. Install the drain bolt and its new
gasket, and then tighten the bolt
to the specified torque.
6. Refill with the specified amount of
the recommended transmission
oil, and then install and tighten the
oil filler cap.
