🔧 Shift Drum Stopper · 4-Speed Positioning Plate · Gear Positioner · CG125/CG150 Specific

For CG125, CG150 Air Cooled 4-Stroke Engines · 4-Finger Design · 4-Speed Gear Positioning

This is the CG Shift Drum Stopper (4-Finger Plate) — a replacement shift drum stopper assembly for CG125 and CG150 air cooled 4-stroke engines. This component is a critical part of the transmission shifting mechanism, responsible for precisely positioning the shift drum to ensure accurate engagement and retention for the 4-speed transmission system.

The shift drum stopper (also known as the gear positioner or shift ratchet stopper) is installed inside the transmission, working with the positioning grooves on the shift drum to provide distinct shift feel and prevent gear jumping during operation. This product features a 4-finger plate design with multiple stopper plates and springs, specifically designed for 4-speed transmission systems, offering precise positioning and reliable operation. This is the perfect replacement when the original stopper suffers from wear, deformation, or spring fatigue causing vague shifting or gear jumping.

This shift drum stopper is compatible with the following engines and vehicles:

• Engine Types: CG125, CG150 Air Cooled 4-stroke engines
• Transmission System: 4-speed transmission
• Vehicle Types: Honda CG series, Chinese-made CG series motorcycles, dirt bikes, street bikes
• Mounting Location: Inside transmission, shift drum side
• Applications: Vague shifting repair, gear jumping repair, transmission overhaul, worn stopper replacement

• 4-Finger Design: Specifically designed for 4-speed transmission systems, with 4 stopper plates precisely engaging with 4-position shift drum grooves for accurate and stable positioning.
• High-Quality Steel: Made from high-strength spring steel with heat treatment for excellent wear resistance and consistent spring tension.
• Precision Machining: Stopper plates are precision-stamped and heat-treated for accurate dimensions and smooth engagement with the shift drum.
• OEM Specification Standards: Manufactured to CG series original specifications for perfect fitment.
• Clear Shift Feel: Optimized 4-finger design provides distinct shift feedback for all 4 gears, enhancing riding experience.
• Essential Transmission Component: The shift drum stopper is a key component of the 4-speed transmission system — this product is critical for restoring proper shift performance.

🔧 Installation Guide

1. Ensure the transmission is removed from the engine or the side cover is opened before starting.
2. Remove the old shift drum stopper, noting the installation order of plates and springs.
3. Inspect the 4-position grooves on the shift drum for wear or deformation.
4. Clean the mounting area, ensuring it is free of oil and debris.
5. Install the new stopper, ensuring the 4 stopper plates engage correctly with the 4-position shift drum grooves and springs are properly seated.
6. Tighten the mounting bolt to the specified torque.
7. Manually rotate the shift drum and check that each of the 4 gear positions is distinct and accurate.
8. It is recommended to inspect the shift drum, shift forks, and springs for wear and replace if necessary.

⚠️ Important Notice: This product is the CG Shift Drum Stopper (4-Finger Plate), also known as the 4-Speed Positioning Plate, designed for the 4-speed transmission system of CG125 and CG150 air cooled 4-stroke engines.
Spec Confirmation: Before purchasing, verify that your transmission is 4-speed and the original shift drum stopper is the 4-finger type to ensure compatibility.
Installation Caution: Pay attention to the installation order of plates and springs. Ensure all 4 stopper plates engage correctly with the 4-position shift drum grooves. After installation, manually test all 4 gear positions to ensure accurate engagement. Professional installation is recommended.
