Harley Crankcase Breather Kit: My Experience and Why It’s Necessary

As an avid Harley rider, I have come to understand the importance of maintaining the engine and ensuring its longevity. One crucial aspect of this is proper ventilation for the crankcase. This is where a Harley crankcase breather kit comes in.

The crankcase breather kit serves as a ventilation system for the engine, allowing the release of any excess pressure that builds up inside. Without this, it can lead to a build-up of moisture and oil, which can result in damage to critical engine components. I learned this the hard way when my bike suffered from oil leaks due to a clogged breather system.

Aside from preventing potential damage, installing a crankcase breather kit also helps improve overall engine performance. When there is proper ventilation, it allows for better fuel combustion and reduces the risk of overheating. It also helps to reduce emissions and keeps your bike running smoothly.

Furthermore, a Harley crankcase breather kit is relatively easy to install and cost-effective. It typically consists of a filter and hose that can be easily attached to your bike’s existing breather system. With regular maintenance and cleaning, it can last for many years.

In my experience,

My Buying Guide on Harley Crankcase Breather Kit

Hello, fellow Harley enthusiasts! As a proud owner of a Harley-Davidson motorcycle, I understand the importance of keeping our bikes in top condition. One crucial part that often gets overlooked is the crankcase breather kit. After experiencing issues with my own bike’s crankcase breather, I decided to do some research and invest in a reliable kit. In this buying guide, I will share my knowledge and personal experience to help you choose the best Harley crankcase breather kit for your bike.

What is a Crankcase Breather Kit?

Before diving into the buying guide, let’s first understand what a crankcase breather kit is and why it’s essential for your Harley. A crankcase breather kit is responsible for releasing excess pressure and filtering out harmful contaminants from the engine’s internal components. It ensures proper ventilation and prevents build-up of sludge or debris that can damage your engine.

Factors to Consider

Now that we know the importance of a crankcase breather kit let’s look at some factors to consider before making a purchase.

Type of Breather Kit

The first thing to consider is the type of breather kit you need for your bike. There are two types available – vented and non-vented. Vented kits release excess pressure into the atmosphere, while non-vented kits re-circulate it back into the intake system. Non-vented kits are more environmentally friendly, but they may require additional modifications to your bike’s intake system.

Compatibility

It is crucial to ensure that the breather kit you choose is compatible with your specific Harley model. Some kits are designed specifically for certain models, while others have universal fitment options. Consult with your mechanic or refer to your bike’s manual before making a purchase.

Quality and Durability

A high-quality crankcase breather kit can significantly improve the performance and longevity of your Harley’s engine. Look for kits made from durable materials such as stainless steel or aluminum, which can withstand high temperatures and harsh riding conditions.

Budget

Crankcase breather kits come in different price ranges, so it’s essential to set a budget before starting your search. While it may be tempting to go for cheaper options, remember that investing in a good quality kit will save you from potential engine damage in the long run.

Top Brands

To make things easier for you, here are some top brands that offer reliable crankcase breather kits for Harley-Davidson motorcycles:

  • S&S Cycle
  • Arlen Ness
  • Roland Sands Design
  • Kuryakyn
  • Vance & Hines

In Conclusion

A properly functioning crankcase breather kit is essential for maintaining your Harley’s engine health. By considering factors like type, compatibility, quality, durability, and budget while choosing a kit from reputable brands like S&S Cycle or Arlen Ness, you can ensure long-term performance from your beloved bike. Happy riding!
