The Importance of a Harley Crankcase Breather Kit

I have been riding Harley Davidson motorcycles for years now, and one thing I have learned is the importance of proper maintenance. One crucial aspect of maintaining a Harley is ensuring that the crankcase is properly ventilated. This is where the Harley crankcase breather kit comes into play.

The crankcase breather kit is designed to prevent harmful pressure buildup within the engine. As the engine runs, it produces gases that need to be released from the crankcase. Without a proper breather system, these gases can build up and cause damage to engine components such as seals and gaskets.

Furthermore, a poorly ventilated crankcase can lead to oil leaks and reduced engine performance. The buildup of pressure can push oil out through any available opening, leading to messy and costly repairs. Additionally, if the pressure is not released properly, it can cause drag on the moving parts of the engine, resulting in reduced power output.

A Harley crankcase breather kit ensures that these harmful gases are safely released from the engine while also preventing any debris or contaminants from entering. This helps to keep your engine running smoothly and extends its lifespan.

In conclusion, a Harley crankcase breather kit is an essential component for

My Buying Guide on Harley Crankcase Breather Kit

As a proud owner of a Harley Davidson motorcycle, I have learned the importance of maintaining its performance and longevity. One crucial aspect of maintenance is ensuring proper ventilation in the crankcase to prevent oil leaks and engine damage. This is where a Harley crankcase breather kit comes into play.

What is a Harley Crankcase Breather Kit?

A Harley crankcase breather kit is an aftermarket accessory designed to improve the ventilation system of your motorcycle’s engine. It replaces the stock breather system, which can be restrictive and lead to oil leaks and other issues.

Why Do You Need a Crankcase Breather Kit?

The stock breather system on Harley motorcycles can become clogged over time, leading to inadequate ventilation and pressure buildup in the crankcase. This can result in oil leaks, decreased engine performance, and even engine damage. A crankcase breather kit allows for better airflow and reduces the risk of these issues.

Things to Consider Before Buying a Crankcase Breather Kit

Before purchasing a crankcase breather kit for your Harley, there are a few things you should consider:

1. Compatibility: Make sure the kit is compatible with your specific model and year of Harley Davidson motorcycle.

2. Quality: Look for kits made from high-quality materials such as aluminum or stainless steel for durability.

3. Installation: Some kits may require modifications or professional installation, so make sure you are comfortable with the process before purchasing.

4. Maintenance: Consider how easy it will be to clean and maintain the breather kit once installed.

Top Features to Look For

When shopping for a crankcase breather kit, here are some key features you should look for:

1. High-flow Design: A high-flow design allows for better ventilation and reduces pressure buildup in the crankcase.

2. Washable Filter: A washable filter makes maintenance easier and more cost-effective in the long run.

3. Catch Can Option: Some kits come with an additional catch can that collects excess oil vapor before it enters back into the engine, further reducing oil leaks.

Final Thoughts

Investing in a high-quality crankcase breather kit is essential for maintaining your Harley Davidson’s performance and preventing potential issues down the road. Be sure to do thorough research on different brands and models before making a purchase to ensure compatibility with your bike. With proper installation and maintenance, a good quality crankcase breather kit will keep your engine running smoothly for years to come.
