Pros and Cons of Buying Motorfactory 1340cc Piston for Harley-Davidson Shovelhead Engines

Introduction:

The Motorfactory 1340cc piston (Part Number: 16926) is a popular aftermarket upgrade for Harley-Davidson Shovelhead engines. This piston offers increased compression and improved engine performance. In this article, we will discuss the pros and cons of buying this piston to help you make an informed decision.

Pros:

1. Increased Compression: The Motorfactory 1340cc piston provides a compression ratio of approximately 9.2:1, which is higher than the stock Shovelhead pistons. This results in increased power output and improved engine efficiency.

3. Oversized Piston: The Motorfactory 1340cc piston is larger than the stock piston, which allows for larger fuel and air charge to enter the cylinder. This results in more efficient combustion and increased power output.

Cons:

1. Complex Installation: Installing the Motorfactory 1340cc piston requires a significant amount of expertise and specialized tools. The process involves disassembling the engine, boring the cylinders, and installing the new pistons.

2. Cost: The cost of purchasing and installing the Motorfactory 1340cc piston can be quite high. The piston itself costs several hundred dollars, and the installation process may require additional labor and parts costs.

3. Risk of Engine Damage: Installing larger pistons, like the Motorfactory 1340cc piston, can increase the risk of engine damage if not done correctly. Improper installation or improperly matched engine components can lead to engine damage, such as bent connecting rods or damaged cylinder walls.

Conclusion:
