### **Pros and Cons of Buying a 1979 1984 Harley-Davidson Shovelhead FLH/FX Sturgis (VIN 35709-79)**

#### **Pros**

1. **Classic Shovelhead Engine**

- The Shovelhead is one of Harley-Davidson s most iconic and well-regarded engines, known for its smooth power delivery, durability, and timeless sound. It s a favorite among enthusiasts for its raw, unfiltered character.

2. **Strong Community & Aftermarket Support**

- The Shovelhead era (1970 1985) has a dedicated following, meaning parts, modifications, and restoration resources are widely available. Aftermarket support for engines, transmissions, and customization is robust.

3. **Reliable Transmission (VTG Shovelhead)**

- The **VTG (Variable Torque Gear)** transmission was introduced in 1979 as an upgrade over the older constant-mesh design. It offers smoother shifting and better power transfer, reducing wear compared to earlier models.

4. **Sturgis Edition Appeal**

- The **FLH/FX Sturgis** models were special editions released in the late '70s, often featuring unique paint schemes, chrome details, and sometimes upgraded components. These bikes are highly sought after by collectors, adding resale value.

5. **Potential for Restoration & Customization**

- Many Shovelheads are stripped down for restorations, allowing owners to rebuild them to near-mint condition. The bike s classic styling makes it a great candidate for custom paint, chrome, or performance mods.

6. **Lower Running Costs (Compared to Modern Harleys)**

- While not as fuel-efficient as modern bikes, Shovelheads are relatively simple and inexpensive to maintain. Basic repairs (oil changes, valve adjustments, chain maintenance) are straightforward and cost-effective.

7. **Nostalgia & Riding Experience**

- For riders who appreciate the raw, unfiltered Harley experience, the Shovelhead offers a different feel compared to modern fuel-injected models. The weight, vibration, and sound create a unique connection to Harley s golden era.

---

#### **Cons**

1. **Age & Wear**

- Bikes from this era are **30 years old**, meaning they may have significant wear in the engine, transmission, drivetrain, or frame. Rust, worn-out bearings, and outdated suspension can be common issues.

2. **Transmission Reliability Concerns**

- While the VTG transmission is an improvement, it s still a **constant-mesh design** with a single dry plate clutch. Over time, clutch slippage, worn synchronizers, and shifting issues can develop. The transmission may require frequent attention.

3. **Fuel & Emissions Challenges**

- These bikes were not designed for modern fuel standards. Running them on modern gasoline (especially ethanol-blended) can cause **carbon buildup, gasket failures, and fuel system issues**. Some owners modify fuel systems or use additives to mitigate problems.

4. **High Maintenance Requirements**

- The Shovelhead requires **regular valve adjustments** (every 1,000 2,000 miles), chain tensioning, and oil changes. Neglecting maintenance can lead to catastrophic engine failure.

5. **Parts Availability & Cost**

- While parts are available, some **OEM components (especially for older models) can be expensive or hard to find**. Aftermarket parts are plentiful but may not always match the original fit and finish.

6. **Rust & Frame Integrity**

- Many Shovelheads suffer from **frame rust**, particularly in the swingarm, rear fender mounts, and exhaust headers. A thorough inspection is crucial before purchase.

7. **Riding Characteristics**

- The Shovelhead is **heavy, vibration-heavy, and not as refined** as modern Harleys. The lack of suspension tuning, ergonomics, and modern safety features (like ABS) can make long rides uncomfortable.

8. **Resale Value Depends on Condition**

- While Sturgis editions hold value, a well-maintained example can sell for **$8,000 $15,000 **, but a neglected one may only fetch **$3,000 $6,000**. Condition is everything.

---

### **Conclusion & Recommendation**

- You **love classic motorcycles** and don t mind maintenance.

- You re prepared for **restoration or frequent upkeep**.

- You appreciate the **raw, unfiltered Harley experience** over modern comforts.

- You have access to **mechanic support** or are willing to learn DIY repairs.

- You re okay with **higher fuel and part costs** compared to newer bikes.

- You want a **plug-and-play, low-maintenance** motorcycle.

- You re not comfortable with **rust, engine rebuilds, or transmission work**.

- You plan to ride it **heavily without proper maintenance**.

- You re not willing to **invest time and money** into bringing it to good condition.

If you find a **well-documented, restored, or mechanically sound** example (preferably with a **clean title, no frame rust, and a rebuilt engine**), it can be an **excellent investment** both for riding and resale. However, if you re buying a **project bike**, be prepared for **significant costs** before it s road-legal and enjoyable.

- **Get a pre-purchase inspection** (especially of the engine, transmission, and frame).

- **Check for rust** (especially in the swingarm, rear fender, and exhaust).

- **Verify service records** (oil changes, valve adjustments, clutch/track adjustments).

- **Budget for a rebuild** if the bike is neglected.

For the right buyer, this Shovelhead is a **piece of motorcycle history** but it demands respect and care. If you re passionate about Harleys and willing to put in the work, it can be an incredibly rewarding ride.
