6. Measure:

●

Compression pressure
Out of specification

→

Refer to steps (c) and

(d).

▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼

a. Set the main switch to “ON”.
b. With the throttle wide open, press the start

button until the reading on the compression
gauge stabilizes.

WARNING

EWA12940

To prevent sparking, ground all spark plug
leads before cranking the engine.

NOTE:

●

Make use the battery is fully charged when tak-
ing measurements.

●

Make sure there is no compression leakage
from the connecting section of the compres-
sion gauge.

●

The difference in compression pressure be-
tween cylinders should not exceed 100 kPa (1
kg/cm

, 14 psi).

c. If the compression pressure is above the

maximum specification, check the cylinder
head, valve surfaces and piston crown for
carbon deposits.
Carbon deposits

→

Eliminate.

d. If the compression pressure is below the min-

imum specification, pour a teaspoonful of en-
gine oil into the spark plug bore and measure
again.
Refer to the following table.

CHECKING THE ENGINE OIL LEVEL

1. Stand the vehicle on a level surface.

NOTE:

●

Place the vehicle on a center stand.

●

Make sure the vehicle is upright.

2. Start the engine, warm it up for several min-

utes, and then turn it off.

3. Check:

●

Engine oil level
The engine oil level should be between the
minimum level mark “a” and maximum level
mark “b”.
Below the minimum level mark

→

Add the

recommended engine oil to the proper level.
