TROUBLESHOOTING
Suspension Troubleshooting -- Models with X-10
Problem Solution
Rear suspension bottoms too easily -Increase torsion spring preload
-Increase rear shock compression valving by
turning screw clockwise (if equipped with op-
tional Indy Select shock)
--Change to heavier valving (if equipped with
Fox™ shocks)
--Increase torsion spring wire diameter
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 compo-
nents are free turning
-Make sure skags are straight on skis
-Check hi-fax and replace if worn
-Reduce ski pressure:
D Increase front track spring preload
D Reduce IFS spring preload by adjusting
cam or threaded adjuster
D
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:
D Increase front track spring preload
D Reduce IFS spring preload by adjusting
cam
D
Reduce rear torsion spring preload
Setting up for deep snow operation -Change worn hi-fax
-Move front track shock assembly to upper
position
