Review S CYCLE Scycle Mn/pq0bsbreather Conversion Kit Harley Davidson Um fits DYNA FXDL 1993–1998

The **Cycle MN/PQ0BS Breather Conversion Kit** is a meticulously engineered aftermarket solution designed to transform the stock air intake system of your **1993 1998 Harley-Davidson FXDL Dyna (MN/PQ0B series)** into a high-performance, free-breathing setup that maximizes airflow and throttle response. Engineered by Cycle Engineering, a trusted name in Harley-Davidson performance modifications, this kit replaces the restrictive stock airbox and intake tract with a sleek, lightweight, and highly efficient system that significantly enhances engine breathing especially under heavy load or at higher RPMs. The conversion features a **high-flow, dual-element air filter assembly** housed in a custom-fabricated aluminum intake box, which not only improves filtration efficiency but also reduces intake restriction, allowing the **Evo V-Twin (883cc)** to draw in more oxygen-rich air for optimal combustion. The kit includes a **direct-fit intake manifold adapter**, ensuring a seamless connection to your stock or upgraded throttle body, while the **high-quality foam or cotton-wrapped filter media** provides superior dirt and debris protection without sacrificing airflow. Beyond performance gains, the Cycle MN/PQ0BS kit also offers a subtle yet noticeable aesthetic upgrade, with its clean, modern design complementing the aggressive styling of the Dyna platform. Whether you re chasing extra horsepower for spirited cruising or simply seeking a more responsive ride, this breather conversion is a straightforward yet impactful modification that delivers measurable improvements in power delivery, smoothness, and overall engine efficiency. Backed by Cycle Engineering s reputation for precision engineering and compatibility, this kit is an ideal choice for riders looking to breathe new life into their FXDL without the complexity of a full intake swap.

### Pros and Cons of buying a Cycle MN/PQ0BS Breather Conversion Kit for a 1993 1998 Harley-Davidson FXDL Dyna (MN/PQ0B)

#### **Pros**

1. **Improved Engine Breathing and Performance**

The breather conversion kit replaces the stock air box with a more efficient system, reducing backpressure and allowing the engine to breathe better. This can lead to smoother acceleration, better throttle response, and improved power delivery, particularly noticeable in the mid-range RPMs where the FXDL s engine excels.

2. **Enhanced Cooling**

The stock air box can restrict airflow, causing the engine to run slightly hotter. The conversion kit improves airflow to the cylinder heads and engine bay, which helps maintain optimal operating temperatures, reducing the risk of overheating especially in stop-and-go traffic or high-temperature conditions.

3. **Reduced Engine Noise**

While the FXDL is already a relatively quiet Dyna, the stock air box can amplify some exhaust and intake noises. The breather conversion kit often muffles these sounds slightly, creating a cleaner, more refined exhaust note.

4. **Easier Maintenance Access**

The new breather system typically requires less frequent cleaning or replacement of the air filter compared to the stock setup, as it is designed to be more durable and less prone to clogging.

5. **Compatibility with Performance Mods**

If you plan to add other performance upgrades (e.g., headers, exhaust, or carburetor tuning), the breather conversion provides a solid foundation for improved airflow throughout the intake and exhaust systems.

6. **Aesthetic Improvement**

The stock air box is often considered bulky and outdated. The Cycle MN/PQ0BS kit replaces it with a cleaner, more modern-looking design that complements the Dyna s aggressive styling.

7. **Potential Fuel Efficiency Gains**

With better airflow and reduced backpressure, some riders report slight improvements in fuel economy, though the FXDL was never known for exceptional MPG to begin with.

---

#### **Cons**

1. **Cost**

The Cycle MN/PQ0BS breather conversion kit is not cheap, typically ranging between $200 $300 depending on the retailer and any additional components (e.g., gaskets, mounting hardware). This is a significant investment for a relatively simple modification, especially if you re on a budget.

2. **Installation Complexity**

While the kit is designed for relatively straightforward installation, it requires removing the stock air box, disconnecting wiring harnesses, and ensuring proper sealing of new gaskets. If you re not comfortable with basic mechanical work, you may need to pay a shop for labor, adding to the cost.

3. **Potential for Leaks**

The new breather system relies on proper sealing of gaskets and connections. If not installed correctly, air leaks can develop, negating the performance benefits and potentially causing the engine to run rough or lose power.

4. **Limited Performance Gains**

The FXDL s engine is already well-tuned for its era, and while the breather conversion will improve breathing, the gains may not be dramatic. Expect noticeable but modest improvements rather than a significant power surge. For serious performance tuning, other mods (e.g., headers, carburetor upgrades, or ECU tuning) would be more impactful.

5. **Compatibility with Aftermarket Parts**

Some aftermarket performance parts (e.g., certain exhaust systems or intake manifolds) may not integrate perfectly with the new breather setup. You ll need to ensure compatibility before purchasing additional mods.

6. **Potential for Increased Oil Consumption**

In rare cases, improved airflow can lead to slightly higher oil consumption, though this is not a common issue with the FXDL. Monitor oil levels regularly if you notice any changes.

7. **Warranty Concerns**

If your bike is under warranty (unlikely for a 1993 1998 model), modifying the breather system could void certain coverage, though this is usually a non-issue for older Harleys.

---

### **Conclusion**

The Cycle MN/PQ0BS breather conversion kit is a worthwhile upgrade for the 1993 1998 FXDL Dyna if you prioritize improved engine breathing, cooling, and a cleaner sound. The performance gains are modest but noticeable, and the aesthetic upgrade is a significant plus. However, the cost and installation effort may not justify the upgrade for riders who are primarily concerned with reliability or those on a tight budget.

If you re already planning other performance mods (e.g., headers, exhaust, or carburetor work), the breather conversion makes sense as part of a broader tuning package. For a stock or lightly modified FXDL, the benefits are more about refinement than raw power.

### **Recommendation**

- You want smoother acceleration and better throttle response.

- You re bothered by the stock air box s noise or appearance.

- You plan to add other performance upgrades in the future.

- You re willing to invest in a modification that enhances the bike s overall feel and reliability.

- You re satisfied with the stock performance and don t want to spend the money.

- You prefer minimal modifications and prioritize simplicity.

- You re unsure about your ability to install it correctly without professional help.

For most FXDL owners, the breather conversion is a **positive upgrade** that enhances the riding experience without being overly aggressive. If you decide to proceed, follow the installation instructions carefully and ensure all gaskets are properly sealed to avoid leaks.
