Part of #33 on the Clutch Diagrag
The heat shield spring works in tandem with the clutch cable to product the cable housing from the heat of the engine. It slips over the clutch cable housing and sits behind the clutch screw base. While its absence will not keep your bike engine from running, it is strongly recommended to ensure the cables integrity.
