Defect

An improper manufacturing process of the right-side crankcase cover allows paint to adhere to the press-fit area of the sealing plug. Engine heat reduces the plug's retention force over time, eventually causing the plug to eject and engine oil to spray out. In the worst case, sprayed oil contacting the rider may cause burns; oil contacting high-temperature components such as the exhaust pipe may cause a vehicle fire; and oil contacting the rear tire may cause the vehicle to fall.

Corrective action

On all vehicles, replace the right-side crankcase cover with a corrected part. Because parts require time to prepare, owners will be notified of the defect and advised to take precautions; replacement will be performed once parts are available.

状況

原動機において、右側クランクケースカバーの製造工程が不適切なため、シーリングプラグの圧入部に塗装が付着しているものがある。そのため、エンジン等の熱により当該シーリングプラグの保持力が低下し、そのまま使用を続けると、シーリングプラグが抜け、エンジンオイルが噴き出し、最悪の場合、運転者に付着すると火傷、飛散したエンジンオイルが排気管等の高温部に付着すると火災、後輪タイヤに付着すると転倒のおそれがある。

改善措置

全車両、右側クランクケースカバーを良品と交換する。なお、改善措置用部品の準備に時間を要することから、使用者に不具合の内容を通知して注意喚起を行い、準備が整い次第交換する。
