TYPICAL
1. Adjustment holes (stopper strap)
NOTE: Decreasing the stopper strap
length may reduce comfort. If too
much weigh t transfer is felt, try to cor-
rect it by adjusting the coupling blocks
first.
When ope ra ting the snowmobile in
deep snow, it may be necessary t o vary
stopper strap length and/or riding posi-
tion, to change the angle at which the
track rides on the snow. Operator's fa-
miliarity w ith the various adjustments
as well as snow conditions will dictate
the most efficient combination.
Generally, a longer stopper strap set-
ting gives better performance in deep
snow on a flat landscape.
Rear Springs
Rear spring preloa d has an effect on
comfort, ride height and load compen-
sation.
Also, adjusting rear spring preload
shifts more or less weight to the snow-
mobile front end. As a result, more or
less weight is applied to the skis. This
has an effect on performance in deep
snow, steering effort and handling.
Slight suspension bottoming occurring
under the worst riding conditions indi-
cates a good choice of spring preload.
ACTION RESULT

More bump absorption
capability
Increasing
preload
Heavier steering
Softer rear suspension
Lower rear end
Less bump absorption
capability
Lighter steering
Decreasing
preload
Better perform ance and
handling in deep snow
