Back Plate Fastener for FZ70S - YS Engine YSG1047  [YSG1047]

Rear plate fastener specifics for FZ70S

This RC back plate screw is supplied for the YS Engine YSG1047 product line and is intended to fit the FZ70S rear plate assembly referenced in the title. The item restores the mechanical fixing of the engine's rear cover when originals are worn or missing.

Fitting is simple: position the rear plate, begin the screw by hand to ensure proper alignment, and secure it until the plate is flush. Avoid excessive torque to protect the screw threads and the plate seating. A correctly tightened fastener helps maintain the seal and reduces vibration-related loosening.

In workshop or track-side maintenance the screw plays a modest but important role, keeping the rear plate secured so internal components remain correctly contained and serviceable. Keep spares for regular servicing or after part loss.
