- Compatibility: Not all big bore kits are compatible with every motorcycle model. Make sure to check if the kit is specifically designed for your 125cc Gy6 engine.
- Cylinder Material: Most big bore kits come with either aluminum or cast iron cylinders. Aluminum cylinders offer better heat dissipation while cast iron cylinders provide more durability.
- Piston Rings: High-quality piston rings are crucial for optimal performance and longevity of your engine. Look for kits that include heavy-duty rings made from high-grade materials.
- Tuning Requirements: Installing a big bore kit may require tuning adjustments such as rejetting the carburetor or adjusting the fuel injection system. Make sure you are comfortable with these modifications or seek professional help if needed.
