CDHPOWER PK80 ZL40 Long Connecting Rod Set for 2 Stroke PK80, 66CC/80CC High Hole Piston Set for Gas Motorized Bicycle

The connecting rod set, consisting of the longer variant, is designed for use with 66cc/80cc/PK80 high-hole piston engines. This set includes both the upper and lower bearings, and is clearly marked with the designation "ZL40".

It's important to note that the piston itself is not included with this connecting rod set, and must be purchased separately. This allows for greater flexibility in matching the appropriate piston to your specific engine requirements.

The use of a high-hole piston design in these 66cc, 80cc, and PK80 engines offers several potential benefits. The increased height of the piston's gudgeon pin bore can contribute to improved engine performance and efficiency, as well as enhanced durability and reliability under demanding operating conditions.

By offering this connecting rod set as a distinct component, users have the opportunity to upgrade or replace the connecting rods without the need to purchase an entire piston assembly. This can be a cost-effective solution for situations where the piston itself remains in good condition, but the connecting rods require servicing or replacement.

The inclusion of both the upper and lower bearings in this set ensures that all the necessary parts are readily available, simplifying the installation process and reducing the risk of compatibility issues. The clear "ZL40" marking helps to quickly identify the specific model and ensure the correct components are selected for the intended application.

Whether you're maintaining an existing 66cc, 80cc, or PK80 engine, or embarking on a custom build or modification project, this connecting rod set can be a valuable addition to your parts inventory. Its durable construction and compatibility with high-hole piston designs make it a reliable choice for a wide range of applications.

Remember, while this connecting rod set is a crucial component, it's essential to carefully follow the manufacturer's instructions and safety guidelines during installation and use. Proper maintenance and regular inspections can help ensure the longevity and optimal performance of your engine.
