(YFM70KPXJ / YFM70KPAJ /
YFM70KPHJ / YFM70KPSJ)The spring preload can be adjusted to suit the rid-
er’s weight and the riding conditions.
WARNING
EWB00401Always adjust the shock absorber assemblies
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 ac-
cident. Adjust the spring preload as follows.
Turn the spring preload adjusting ring in direction
(a) to increase the spring preload and thereby
harden the suspension, and in direction (b) to de-
crease the spring preload and thereby soften the
suspension. Align the appropriate notch in the adjusting ring
with the position indicator on the shock absorber.
TIPA special wrench can be obtained at a Yamaha
dealer to make this adjustment. 1. Spring preload adjusting ring

EBU19185Auxiliary DC jackA 12-V accessory, such as a work light or radio
with the proper adapter, can be used when the en-
gine is running and the headlights are turned off.1. Start the engine. (See page 6-1.)
2. Turn the headlights off. (See page 4-10.)
3. Turn the accessory off.
4. Open the auxiliary DC jack cap.
5. Insert the accessory power plug into the jack. 6. Turn the accessory on.
TIP
When inserting or removing the accessory pow-
er plug, turn the accessory off.
When the auxiliary DC jack is not being used,
cover it with the cap. NOTICEECB00121Do not use accessories requiring more than
the above maximum capacity. This may
overload the circuit and cause the fuse to
blow.
If accessories are used without the engine
running or with the headlights turned on, the
battery will lose its charge and engine start-
ing may become difficult.
Do not use an automotive cigarette lighter or
other accessories with a plug that gets hot
because the jack can be damaged.
