Compression damping (for slow compres-

sion damping)

NOTICE

ECA24390

Do not turn the adjuster forcibly beyond its

adjusting range.

1. Adjust:

•

Compression damping (for slow compression
damping)
a. Turn the adjuster “1” in the direction of “a”

or “b” to make an adjustment.

TIP

Although the total number of clicks of a damping
force adjusting mechanism may not exactly
match the above specifications due to small dif-
ferences in production, the actual number of
clicks always represents the entire adjusting
range. To obtain a precise adjustment, it would
be advisable to check the number of clicks of
each damping force adjusting mechanism and
to modify the specifications as necessary.

CHECKING THE SWINGARM OPERATION

1. Check:

•

Swingarm smooth action

•

Swingarm free play
Refer to “SWINGARM” on page 4-65.

EAM30500

LUBRICATING THE SWINGARM PIVOT

1. Lubricate:

•

Oil seals

•

Collars

Refer to “INSTALLING THE SWINGARM” on
page 4-66.

EAM30501

CHECKING THE CONNECTING ARM AND

RELAY ARM

Refer to “CHECKING THE CONNECTING ARM
AND RELAY ARM” on page 4-63.

EAM30243

CHECKING THE TIRES

1. Measure:

•

Tire pressure
Out of specification



Regulate.

TIP

•

Check the tire while it is cold.

•

Because if the bead stopper tightening nut is
loose when the tire pressure is low, the tire
could slip off the rim, thus be sure to check and
tighten the bead stopper tightening nut “a”.

•

If the tire valve stem “b” is found tilted, the tire
is considered to be slipping off its position. Cor-

Direction “a”

Compression damping is increased

(suspension is harder).

Direction “b”

Compression damping is decreased

(suspension is softer).

Slow compression damping

Minimum (soft)

20 click(s) in direction “b”*

Standard

9 click(s) in direction “b”*

Maximum (hard)

0 click(s) in direction “b”*

* With the adjusting screw fully turned in di-

rection “a”
