CLUTCH SPRING PRELOAD
Clutch spring preload affects the point at which the clutch engages, and is
altered by tightening or loosening the spring preload collar. This is done with
the engine stopped, and without disassembling the clutch.
Effects of Clutch Spring Preload Adjustment
Lighter Spring Preload
• Earlier engagement
• Better on slippery tracks
Heavier Spring Preload
• Later engagement
• Better on smooth, high-traction
tracks
