CHECKING THE SPARK PLUGS
CHK
ADJ
CAUTION:
EAS00059
CHECKING THE SPARK PLUGS
The following procedure applies to all of the
spark plugs.
1. Remove:

side cowlings

bottom cowlings
Refer to “COWLINGS”.
2. Remove:

radiator upper bolts

radiator lower bolt
Refer to “RADIATOR” in chapter 6.
3. Remove:

ignition coils

spark plugs
Before removing the spark plugs, blow away
any dirt accumulated in the spark plug wells
with compressed air to prevent it from fal-
ling into the cylinders.
4. Check:

spark plug type
Incorrect
Change.
Spark plug type (manufacturer)

Damage / wear
Replace the spark plug.

Abnormal color
Replace the spark plug.
Normal color is medium-to-light tan.
6. Clean:

Before checking the engine oil level, wait a few
minutes until the oil has settled.
4. Start the engine, warm it up for several min-
utes, and then turn it off.
5. Check the engine oil level again.

CHECKING THE BRAKE FLUID LEVEL
CHK
ADJ
NOTE:
WARNING
CAUTION:
NOTE:
EAS00115
CHECKING THE BRAKE FLUID LEVEL
1. Stand the motorcycle on a level surface.

Place the motorcycle on a suitable stand.

Make sure the motorcycle is upright.
2. Check:

brake fluid level
Below the minimum level mark
a
Add the
recommended brake fluid to the proper level.
Recommended brake fluid
DOT 4
AFront brake
BRear brake

Use only the designated brake fluid. Other
brake fluids may cause the rubber seals to
deteriorate, causing leakage and poor
brake performance.

Refill with the same type of brake fluid that
is already in the system. Mixing brake
fluids may result in a harmful chemical
reaction, leading to poor brake perfor-
mance.

When refilling, be careful that water does
not enter the brake fluid reservoir. Water
will significantly lower the boiling point of
the brake fluid and could cause vapor lock.
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean
up any spilt brake fluid immediately.
In order to ensure a correct reading of the brake
fluid level, make sure the top of the brake fluid
reservoir is horizontal.

NOTE:
WARNING
CAUTION:

While holding the brake hose, tighten the
union bolt.

Turn the handlebars to the left and right to
make sure the brake hose does not touch oth-
er parts (e.g., wire harness, cables, leads).
Correct if necessary.
4. Fill:

mended brake fluid)
