Defect
In the engine, improper process control during cylinder machining leaves the cylinder surface rough. While driving, engine oil is drawn up into the combustion chamber and burned, increasing oil consumption. Insufficient lubrication causes abnormal noise. Continued use may result in engine damage while driving, causing the rear wheel to lock and the vehicle to fall, or a vehicle fire.
Corrective action
On all vehicles, inspect the engine. If an abnormality is found, replace with an engine sub-assembly containing a conforming cylinder. If abnormal noise is present, replace the complete engine assembly.

状況
原動機において、シリンダ加工の工程管理が不適切なため、シリンダ表面が粗くなり、走行中にエンジンオイルが燃焼室まで吸い上げられて燃焼し、オイル消費量が増えることがある。そのため、オイルの潤滑不良で異音が発生し、そのまま使用を続けると、走行中にエンジンが破損し、後輪がロックして転倒する、または、火災に至るおそれがある。
改善措置
全車両、エンジンを点検し、異常がある場合はシリンダの良品が組み込まれたエンジンサブアッセンブリに交換する。また、異音がある場合はエンジンをアッセンブリで交換する。
