SwitchBack Suspension Troubleshooting
Problem Solution (Perform only one change at a time)
Rear suspension
bottoms too easily
• Verify sag dimension (see page 58). Adjust torsion spring
blocks or install optional torsion springs to achieve correct
sag dimensions.
• Increase shock compression damping (see page 64).
Rear suspension
rides too stiff
• Check for binding suspension components and grease all
pivot points.
• Verify sag dimension (see page 58). Adjust torsion spring
blocks or install optional torsion springs to achieve correct
sag dimensions.
• Decrease shock compression damping (see page 64).
Too much weight
transfer when
climbing
• Verify sag dimension (see page 58). Adjust torsion spring
blocks or install optional torsion springs to achieve correct
sag dimensions.
• Move limiter strap on front torque arm to high position (see
page 63).
Too little weight
transfer when
climbing
• Verify sag dimension (see page 58). Adjust torsion spring
blocks or install optional torsion springs to achieve correct
sag dimensions.
• Move limiter strap on front torque arm to low position (see
page 63).
Front end pushes • Check for worn skags
• Check for binding front suspension shafts and steering com-
ponents, grease all pivot points (elevate front of machine).
• Verify sag dimension (see page 58). Adjust torsion spring
blocks or install optional torsion springs to achieve correct
sag dimensions.
• Increase IFS preload (see page 55).
• Move limiter strap on front torque arm to high position (see
page 63).
Steering is heavy • Check skags and skis for damage.
• Check ski alignment (see page 146).
• Make sure spindles and all steering components turn freely.
• Verify sag dimension (see page 58). Adjust torsion spring
blocks or install optional torsion springs to achieve correct
sag dimensions.
• Adjust IFS preload (see page 55).
• Adjust RIDER SELECT (see page 34).
Machine darts from
side to side
• Check ski alignment (see page 146).
• Check for binding front suspension shafts and steering com-
ponents, grease all pivot points (elevate front of machine).
• Ensure skags are straight on skis.
