GY6 49cc-100cc (QMB139) - Shroud - Oil Pump

Shrouds and oil pumps for GY6 49cc–100cc (QMB139) engines play an important role in cooling and lubrication for most Chinese 49–80cc scooters. Proper airflow from intact shrouds helps prevent overheating, while a healthy oil pump keeps internal parts lubricated for smooth, long-lasting performance. If you’re restoring a scooter from brands like TaoTao, Peace Sports, or Jonway, replacing cracked shrouds or a weak oil pump can greatly improve reliability, engine temperature control, and overall durability.
