Yamaha SXV4NP Operator's Manual page 45

Rear spring preload adjustment is accom-
plished by rotating the adjusting cams.
Position 3 provides the stiffest ride, and
position 1 is for the light driver or slow-
speed trail riding. Position 2 is for the
average operator under normal conditions.
Always rotate the cam from the lighter
position to the heavier position.
CAUTION
Never force the adjustment cams
from the low position to the high
position. Cam damage may occur.
Articulating Skid Frame
(Transporter/Transporter
Lite)
The rear articulating portion of the skid
frame has two skid frame blocks which
allow the skid frame to be locked or artic-
ulate.
To allow the rear of the skid frame to
articulate, pull out the knob on the left-
side block and rotate the knob and adjust-
ment block up and forward until it locks
into the upper mounting hole.
Overload Springs

NOTE: Yamaha recommends that
the overload springs be engaged
whenever a load on the snowmobile
(operator/cargo) exceeds 136 kg
(300 lb).
There are weight limitations for these
snowmobiles. If additional cargo is
being added, maximum weight on the
snowmobile (operator/cargo) should

not exceed 170 kg (375 lb). Also, the
overload springs should be engaged.
To either engage or disengage the spring
tension blocks, use a spark plug socket
and a screwdriver to adjust the spring
block to the desired position. Make sure
both spring blocks are in the same posi-
tion (either engaged or disengaged).
