TROUBLESHOOTING
Suspension Troubleshooting
Problem Solution (perform only one change at a time)
Rear suspension
bottoms 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 slider and replace if worn
-Reduce ski pressure:
S
Reduce IFS spring preload
S
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 ad-
juster
-Decrease front limiter strap length
Steering is heavy -Check ski alignment
-Check skags and skis for damage
-Reduce ski pressure:
S
Increase front track spring preload
S
Reduce IFS spring preload by adjusting cam
S
Reduce rear torsion spring preload
Setting up for deep
snow operation -Change worn slider
-Move front track shock assembly to upper position
