TIP●
A special wrench can be obtained at a
Yamaha dealer to make this adjustment.
●
The spring preload setting is determined
by measuring distance A, shown in the il-
lustration. The shorter distance A is, the
lower the spring preload; the longer dis-
tance A is, the higher the spring preload.
With each complete turn of the adjusting
nut, distance A is changed by 1.5 mm
(0.06 in).

TIPAlthough the total number of clicks of a damp-
ing force adjusting mechanism may not exact-
ly match the above specifications due to small
differences in production, the actual number
of clicks always represents the entire adjust-

would be advisable to check the number of
clicks of each damping force adjusting mech-
anism and to modify the specifications as nec-
essary.

WARNING
●
Suspension components become hot
during operation. Never touch the
compression damping force adjusting
screw, the rebound damping force ad-
justing screw or the oil reservoir with
your bare hand or skin until suspen-
sion components have cooled.
●
Always adjust the shock absorber as-
semblies on the left and right side to
the same setting. Uneven adjustment
can cause poor handling and loss of
stability, which could lead to an acci-
dent.

EVU00430Final gear oil
Make sure the final gear oil is at the specified
level. Add oil as necessary. (See pages 8-15–
8-18 for details.)
If desired, an SAE 80W-90 hypoid gear oil
may be used for all conditions.TIPTIPGL-4 is a quality and additive rating; GL-5 or
GL-6 rated hypoid gear oils may also be used.EVU00440Differential gear oil
Make sure the differential gear oil is at the
specified level. Add oil as necessary. (See
pages 8-18–8-21 for details.)
EVU00450Accelerator pedal
Check to see that the accelerator pedal oper-
ates correctly. It must operate smoothly and
spring back to the idle position fully when re-
leased. Have a Yamaha dealer repair as nec-
essary for proper operation.EVU00460Seat belts
Make sure that the seat belts are not frayed,
torn, stretched, or damaged. The seat belts
must move smoothly when pulled out and re-
tract on its own when released. The seat belts
must also lock up when quickly pulled out.
The latch plate should click securely into the
buckle and release when the release button is
pushed firmly. Wash off any dirt or mud that
could affect operation. Have a Yamaha dealer
repair as necessary for proper operation.
