Filing in context

Defect
The piston and top ring were improperly designed, leaving an excessive gap between them. Repeated engine braking from high engine speeds draws engine oil into the combustion chamber, where it burns, 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 leading to a vehicle fire.
Corrective action
On all vehicles, replace the piston and top ring with corrected parts. Additionally, inspect the engine; if abnormal noise is present, replace the engine as an assembly.

状況
原動機において、ピストン及びトップリングの設計が不適切なため、ピストンとトップリングの隙間が広く、エンジンが高回転の状態からエンジンブレーキによる減速を繰り返すと、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、ピストン及びトップリングを対策品と交換する。また、エンジンを点検し、異音がある場合はエンジンをアッセンブリで交換する。
