### **Pros and Cons of Buying Twin Power MN/BW7Y Fittings for a 1984 1989 Harley-Davidson FLTC Tour Glide OM**

#### **Pros**

1. **Improved Power and Performance**

Twin Power kits (such as the MN or BW7Y) replace the stock air-cooled Twin Cam with a more powerful, modern engine. These kits often feature larger displacement, improved cylinder heads, and upgraded internals, resulting in significantly more horsepower and torque. For a 1984 1989 Tour Glide, which was originally equipped with a 1500cc Twin Cam, the upgrade can provide a noticeable boost in acceleration and top-end speed.

2. **Modernized Engine Technology**

Twin Power kits incorporate contemporary engine designs, including improved cylinder head flow, better valve timing, and sometimes even electronic fuel injection (EFI) or high-performance carburetion. This can lead to smoother operation, better throttle response, and improved reliability compared to the stock air-cooled setup.

3. **Enhanced Reliability and Durability**

Many Twin Power kits are built with high-quality materials and modern manufacturing techniques, reducing the risk of common issues found in older Harley engines, such as piston ring wear, cylinder scoring, or head gasket failures. Some kits also include upgraded bearings, crankshafts, and connecting rods, which can extend the engine s lifespan.

4. **Better Fuel Efficiency (Relative to Stock)**

While Twin Power engines are more powerful, some kits are tuned for better efficiency than the stock Twin Cam, especially if paired with a modern fuel system. However, this is not a guarantee, as high-performance tuning can sometimes reduce fuel economy.

5. **Customization and Build Flexibility**

Twin Power kits allow for extensive customization, including the option to pair them with different transmissions (such as a 6-speed or a modern 5-speed), upgraded drivetrains, and aftermarket components. This makes it easier to tailor the bike to your riding style and preferences.

6. **Potential for Higher Resale Value**

If you plan to sell the bike in the future, a Twin Power conversion can make it more attractive to buyers looking for modernized, high-performance Harley-Davidsons. However, this depends on the market and the specific model s popularity.

7. **Reduced Emissions (If Compliance is Achieved)**

Some Twin Power kits are designed to meet modern emissions standards, which can be beneficial if you plan to ride in areas with strict regulations. However, this is not universal, and some kits may require additional modifications to comply.

---

#### **Cons**

1. **High Cost of Conversion**

Twin Power kits are expensive, with prices ranging from **$10,000 to $20,000 or more**, depending on the specific model (MN vs. BW7Y) and whether you include additional components like transmissions, exhaust systems, or fuel systems. This is a significant investment compared to stock or even simpler aftermarket upgrades.

2. **Complex Installation Process**

Converting a 1984 1989 Tour Glide to a Twin Power engine requires extensive mechanical skill, specialized tools, and often the assistance of a professional shop. The process involves removing the stock engine, installing the new block, rebuilding the transmission, and integrating new components like the fuel system, electrical wiring, and drivetrain. This can take **hundreds of hours** of labor.

3. **Potential for Increased Maintenance**

While Twin Power engines are often more reliable than stock Twin Cams, they are still high-performance engines that require **more frequent maintenance**, including oil changes, valve adjustments, and cooling system upkeep (especially if liquid-cooled). Some riders report higher long-term costs due to wear on upgraded components.

4. **Weight Increase**

Twin Power engines are significantly heavier than the stock air-cooled Twin Cam, which can affect handling, especially on a Tour Glide, which is already a heavy bike. This may require additional suspension tuning or weight distribution adjustments.

5. **Compatibility and Fitment Challenges**

While Twin Power kits are designed to fit Harley-Davidson frames, some conversions may require modifications to the frame, swingarm, or drivetrain to ensure proper alignment and function. This can add to the complexity and cost of the project.

6. **Potential for Decreased Reliability if Poorly Installed**

If the conversion is not done correctly, it can lead to **engine failure, transmission issues, or other mechanical problems**. This is why many riders opt for professional installation, which further increases costs.

7. **Resale Value Uncertainty**

While some Twin Power conversions hold value, others may not, depending on the market. If you decide to sell, potential buyers may have mixed opinions on the value of a modified Tour Glide, especially if the bike is heavily customized.

8. **Legal and Insurance Considerations**

Some Twin Power kits may not be street-legal in all states or countries without additional modifications (such as emissions compliance). Additionally, insurance premiums may increase due to the higher value and performance of the modified engine.

---

### **Conclusion**

A Twin Power MN/BW7Y conversion for a 1984 1989 Harley-Davidson FLTC Tour Glide OM is a **significant upgrade** that offers substantial power gains, modernized engine technology, and improved reliability. However, it is also a **costly and labor-intensive** project that requires careful planning, mechanical expertise, and a willingness to invest in long-term maintenance.

If you are an **enthusiast with mechanical skills, a budget for the conversion, and a passion for high-performance motorcycles**, this upgrade can be an exciting and rewarding project. On the other hand, if you prioritize **simplicity, lower cost, or preservation of the original bike s character**, a Twin Power kit may not be the best choice.

---

### **Recommendation**

- **If you want maximum power and modern performance** and are prepared for the financial and mechanical commitment, a Twin Power conversion is a great option.

- **High-performance carburetors or EFI conversion** (e.g., Harley-Davidson Performance or aftermarket systems).

- **Cylinder head porting and polishing** for better airflow.

- **Upgraded exhaust and intake systems** for improved throttle response.

- **A stock Twin Cam rebuild** with modern components (such as forged internals or upgraded camshafts).

- **If you enjoy classic Harley-Davidsons**, preserving the original air-cooled Twin Cam with proper maintenance may be more satisfying than a full conversion.

Ultimately, the decision depends on your **budget, mechanical ability, riding goals, and how much you value the original character of your Tour Glide**. If you proceed with a Twin Power kit, ensure you work with a reputable shop and allocate extra funds for potential unforeseen issues.
