REAR SUSPENSION, SHOCKS AND TRACK 12 - 12
GENERAL INFORMATION
Calibrating the shock absorber so that there is too much
damping is a frequent error. When this is done, the suspension
has too much give. The suspension cannot carry out a
complete extension after the compression caused by a bump.
After some time, the suspension becomes sluggish and no
longer performs the movements of compression and extension
efficiently.
Calibrating the shock absorber so that there is not enough
damping means the damping will either be insufficient or badly
controlled.
In such a case, the shock absorber moves up and down almost
without any restriction. When going over a bump, the symptom
most often noticed is that the snowmobile bounces.
