XTRA LITE
Problem Solution (perform only one change at a time)
Rear suspension
bottoms too easily -Adjust torsion spring block to next higher position
-Increase rear shock compression damping by turning screw
clockwise
-Change torsion springs to next higher rate springs
-Change front track spring to next higher rate
Rides too stiff in
rear -Check for binding suspension shafts and grease all pivot points
-Decrease torsion spring preload adjustments
-Decrease rear shock compression damping by turning screw
counter clockwise
-Change torsion springs to next lower rate springs
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
-Install “E-Z Steer” skags
Front end pushes -Check for worn skags
-Check for binding suspension shafts and grease all pivot points
-Increase IFS preload
-Shorten limiter strap on front torque arm
-Increase torsion spring preload
Steering is heavy -Make sure spindles and all steering components are free turning
-Check ski alignment
-Check skags and skis for damage
-Decrease IFS preload
-Change front track spring to next higher rate
Too much weight
transfer when
climbing -Shorten limiter strap on front torque arm

ward mounting position
Too little weight
transfer when
climbing -Lengthen limiter strap on front torque arm
