EDGE Suspension Troubleshooting
Problem Solution
Rear suspension bot-
toms too easily
• Increase torsion spring preload
• Increase rear shock compression damping by turning
screw clockwise
• Increase torsion spring wire diameter (see your dealer)
Rides too stiff in rear • Check for binding suspension shafts and grease all pivot
points
• Decrease torsion spring preload adjustments
• Decrease rear shock compression valving by turning
screw counterclockwise (if equipped with optional Indy
Select shock)
• Change to lighter valving if (if equipped with FOX
shocks)
• Check for proper track tension
Machine darts from
side to side
• Make sure skis are aligned properly
• Make sure spindles and all steering components are free
turning
• Make sure skags are straight on skis
• Check rail slide and replace if worn
• Reduce ski pressure:
A) Reduce IFS spring preload
B) Reduce rear torsion spring preload
Front end pushes • Check for worn skags
• Check for binding suspension shafts and grease all pivot
points
• Increase IFS spring preload by adjusting cam or threaded
adjuster
• Decrease front limiter strap length
Steering is heavy • Check ski alignment
• Check skags and skis for damage
• Reduce ski pressure:
A) Increase front track spring preload
B) Reduce IFS spring preload by adjusting cam
C) Reduce rear torsion spring preload
Setting up for deep
snow operation
• Change worn Hi-fax
• Move front track shock assembly to upper position
