⚙️ Product Features

OEM Match: Part numbers 0JY0-0400B0-0001 / 0002 correspond exactly with the CFMoto official parts system, ensuring direct replacement.
Precision Dimensions: Features a 91mm piston diameter with high-precision machining for optimal cylinder clearance.
High-Quality Material: Cast from high-strength aluminum alloy, offering excellent heat resistance, wear resistance, and impact strength.
Complete Kit: Includes the piston, pin, rings, and circlips—all core components needed for installation.
Optimized Design: Skirt features special coating and profile design to reduce friction, minimize noise, and enhance durability.
Essential for Rebuilds: Must be replaced during major engine overhauls to ensure cylinder sealing and compression pressure.

✅ Fault Indications: Common signs of piston wear or damage include:
• Blue exhaust smoke (burning oil);
• Low cylinder compression, resulting in power loss;
• Unusual engine noises (e.g., piston slap);
• Excessive oil consumption;
• Heavy carbon deposits on spark plugs.
If these symptoms occur, inspect the piston and cylinder assembly immediately.

✅ Installation Tip: Thoroughly clean the cylinder bore before installation. When installing pistons, ensure piston ring gaps are staggered and use a proper ring compressor to insert the piston into the cylinder. Strictly follow the orientation note: Front cylinder piston mark faces intake side, rear cylinder piston mark faces exhaust side. Professional installation by an experienced technician is recommended.
