TORSION SPRING ADJUSTMENTS
To adjust rear torsion spring preload, rotate the three-position cam
q
using the engine spark plug tool. Adjustment is
easiest when the cam is rotated from low to medium, and then to high. Rotating directly from low to high will require
significantly more effort. Different rate torsion springs are available if a softer or firmer ride is desired.
NOTICE
Adding 1+1 seat, or additional cargo may affect handling and require a spring rate change.
