Review KAWASAKI Oem Kips Valve Powervalve Linkage Lever Shaft fits KX500 1988

The **Kawasaki 13168-1373 1988 KX500 Valve Powervalve Linkage Lever Shaft Assembly** is a meticulously engineered component designed to enhance the performance and reliability of Kawasaki s legendary KX500 motocross bike from the late 1980s. This critical part is part of the bike s advanced **Powervalve** system, a groundbreaking technology introduced by Kawasaki that dynamically adjusts valve timing to optimize engine efficiency across a wide RPM range. The **valve linkage lever shaft** serves as the mechanical interface between the Powervalve actuator and the engine s valve train, ensuring precise and responsive valve operation. Crafted from high-grade steel, this assembly is built to withstand the extreme stresses of high-speed motocross racing, where durability and consistency are paramount. The lever shaft features a robust, machined design with critical pivot points and linkages that minimize friction and maximize durability, allowing the Powervalve system to function seamlessly under heavy loads. Whether restoring a classic KX500 to its original racing glory or upgrading an existing bike for improved throttle response and power delivery, this part is an essential component for maintaining the integrity of Kawasaki s legendary Powervalve technology. Its compatibility with the 1988 model ensures a perfect fit, making it a must-have replacement for enthusiasts seeking to preserve or enhance the performance of their KX500.

### **Pros and Cons of Buying a 1988 Kawasaki KX500 with PowerValve Linkage and Lever Shaft**

#### **Pros**

1. **Classic and Reliable Design**

The 1988 Kawasaki KX500 is a well-regarded model from the late 1980s, known for its durable engine and strong reputation in off-road racing. Kawasaki s air-cooled, single-cylinder design was robust for its time, making it a dependable choice for enthusiasts.

2. **PowerValve Technology (Early Implementation)**

The PowerValve system was an innovative feature in its era, allowing for better throttle response and power delivery. While not as refined as later implementations, this early version still offers a unique riding experience compared to standard carbureted bikes.

3. **Lever Shaft Drivetrain**

The lever shaft (or "chainless" drivetrain) was a rare and desirable feature in the late '80s, reducing maintenance compared to traditional chains. This makes the bike easier to service and less prone to chain stretch or misalignment issues.

4. **Strong Aftermarket Support**

The KX500 has been around for decades, meaning parts, modifications, and tuning options are widely available. Many aftermarket manufacturers still produce components for this model, including carburetors, exhausts, and suspension upgrades.

5. **Potential for Restoration and Customization**

If the bike is in rough condition, it can be a rewarding project. The KX500 has a strong following among restorers, and its simplicity makes it easier to rebuild than more complex modern bikes.

6. **Lower Purchase Price Compared to Modern Bikes**

Due to its age, a 1988 KX500 with PowerValve and lever shaft will likely be significantly cheaper than a new or even a used modern dirt bike, making it an attractive option for budget-conscious buyers.

7. **Nostalgia and Collector Appeal**

For enthusiasts who appreciate classic motocross bikes, this model holds sentimental value. The PowerValve and lever shaft make it a standout example of Kawasaki s experimental engineering from the era.

---

#### **Cons**

1. **Age and Wear**

At nearly 40 years old, the bike will likely show significant wear, including rust, worn-out suspension, and potential engine issues. The PowerValve system, while innovative, may require extra attention to ensure proper function.

2. **Maintenance Requirements**

An air-cooled single-cylinder engine from the '80s will need regular upkeep, including valve adjustments, piston ring checks, and carburetor tuning. The lever shaft, while low-maintenance, may still require occasional lubrication.

3. **Reliability Concerns**

While Kawasaki engines were durable, the 1988 model may have accumulated miles, leading to potential engine wear, cylinder scoring, or bearing failure. A pre-purchase inspection is critical to assess its condition.

4. **Limited Modern Performance**

Compared to modern dirt bikes, the KX500 lacks advanced features like electronic fuel injection, advanced suspension systems, and lightweight materials. It will feel less responsive and less powerful by today s standards.

5. **Parts Availability May Be Limited**

While parts exist, some components (especially OEM) may be harder to find than for newer models. Buyers may need to source parts from specialty shops or online marketplaces.

6. **Safety and Modern Standards**

The bike lacks modern safety features such as ABS, traction control, or advanced crash protection. Riders should be prepared for a more "hands-on" riding experience with less built-in assistance.

7. **Potential for Hidden Issues**

The PowerValve system, while interesting, could introduce additional complexity. If not properly maintained, it may lead to leaks, valve float, or other performance issues. The lever shaft, while durable, may require careful inspection for wear.

### **Conclusion and Recommendation**

The **1988 Kawasaki KX500 with PowerValve linkage and lever shaft** is a fascinating piece of motocross history, offering a unique blend of innovation and durability. It is best suited for:

- **Enthusiasts who appreciate classic bikes** and are willing to invest time in restoration or maintenance.

- **Budget-conscious buyers** who prioritize affordability over modern performance.

- **Riders who enjoy the challenge** of riding a bike with fewer electronic aids and a more "old-school" feel.

- **Project bike owners** who are comfortable with mechanical work and have access to parts.

However, it is **not ideal** for:

- **Casual riders** who want a hassle-free, high-performance bike.

- **Those seeking modern safety and convenience features.**

- **Buyers who cannot commit to regular maintenance and upkeep.**

#### **Final Recommendation:**

If you find this bike in **excellent condition** (or are prepared to restore it thoroughly), it can be a rewarding purchase for a collector or a rider who values nostalgia and mechanical challenge. However, if you are looking for a **reliable, high-performance dirt bike for regular riding**, a modern used or new model would be a more practical choice.

**Before purchasing:**

- **Get a professional inspection** to assess engine, suspension, and drivetrain health.

- **Verify the PowerValve and lever shaft** are in working order.

- **Check for rust, leaks, or signs of neglect** that could lead to costly repairs.

- **Budget for potential restoration costs** if the bike is not already in good shape.

If you are determined to buy, treat it as either a **project bike** or a **collector s item** rather than a daily rider. Otherwise, consider a newer model for better reliability and performance.
