Review KAWASAKI 1979/80 Air Box Intake Breather Filter Oem Housing Original fits KX80 KX 1980

The **1979-1980 Kawasaki KX80 "Kawi" Air Box Intake Breather Filter Housing** is a meticulously crafted, period-correct replacement component designed to restore the iconic performance and authenticity of this legendary 80cc dirt bike. Originally fitted to the KX80 s air-cooled, single-cylinder engine, this filter housing serves as the critical interface between the air intake system and the carburetor, ensuring a clean and unrestricted flow of air while maintaining proper sealing to prevent oil leaks and vacuum loss. Crafted from durable, high-quality materials, the housing features a robust aluminum or die-cast construction, depending on the original specification, with precision-machined surfaces to guarantee a snug fit against the engine s air box and carburetor. The design includes a threaded inlet port for the air filter, typically accommodating a standard paper or foam element, and a smooth, tapered outlet that connects seamlessly to the carburetor s intake, minimizing turbulence and maximizing airflow efficiency. For collectors and restorers seeking to preserve the mechanical integrity of their Kawi, this part is an essential upgrade, as it addresses common wear issues like cracked housings, degraded seals, or corroded mounting points that can plague aging examples. Whether used in a fully restored show bike or a daily-ridden project, this filter housing ensures optimal engine breathing, reduces carbon buildup, and helps maintain the KX80 s legendary reliability making it a must-have for any enthusiast aiming to breathe new life into their classic Kawasaki.

### **Pros and Cons of Buying a Kawasaki KX80 (1979/1980) Air Box Intake Breather Filter Housing**

1. **Authentic Vintage Fitment** The original air box and breather system are designed specifically for the KX80, ensuring a perfect mechanical fit without modifications. This is ideal for restorers or enthusiasts who prioritize period-correct components.

2. **Historical Significance** Owning or restoring a genuine 1979/1980 KX80 part adds value for collectors and those interested in motorcycle history. The air box and breather system are key functional elements that contribute to the bike s original character.

3. **Functional Reliability** The air filter housing and breather system were built to last with proper maintenance. While not as durable as modern components, they were designed for the bike s intended use, making them a logical choice for riders who want to preserve the original feel of the KX80.

4. **Ease of Maintenance** The design is relatively simple, allowing for straightforward cleaning and replacement of the paper air filter. This can be an advantage for those who prefer hands-on upkeep over high-tech solutions.

5. **Compatibility with Modifications** If you plan to restore or modify the KX80, the original air box can serve as a base for upgrades (e.g., swapping in a modern filter or breather system later). It s a flexible starting point.

6. **Lower Cost Compared to Full Bike** Purchasing just the air box and breather housing is significantly cheaper than buying an entire KX80, making it a budget-friendly way to acquire a key component for a project bike.

1. **Age and Wear** Parts from this era are prone to deterioration, including cracked rubber seals, brittle plastic, or degraded gaskets. The air box may require cleaning or replacement of internal components before use.

2. **Limited Availability of Spare Parts** Finding exact replacements for worn-out or broken components (e.g., specific gaskets, seals, or fasteners) can be difficult. You may need to source parts from other vintage bikes or manufacturers.

3. **Durability Concerns** The materials used in the 1970s were not as robust as modern equivalents. The plastic air box housing may become brittle over time, and the breather system could fail if not maintained regularly.

4. **Performance Limitations** The original air filter and breather system are not optimized for modern riding conditions or performance demands. If you plan to use the bike aggressively, you may need to upgrade the filter or breather later to improve airflow and reliability.

5. **Compatibility with Modern Mods** Some aftermarket modifications (e.g., high-performance air filters, larger breather systems, or carburetor upgrades) may not integrate seamlessly with the original air box. You might need to adapt or replace parts to achieve desired performance gains.

6. **Potential for Contamination** Over decades, dust, dirt, and moisture can accumulate inside the air box, clogging the filter or damaging internal components. Thorough cleaning and inspection are essential before use.

7. **Resale Value** While the part itself may have niche appeal, its resale value is limited compared to a fully restored or running KX80. It s primarily valuable to collectors or restorers.

The Kawasaki KX80 air box intake breather filter housing from 1979/1980 is a valuable component for vintage motorcycle enthusiasts, restorers, or those seeking an authentic piece for a project bike. It offers historical accuracy, functional simplicity, and a lower cost than purchasing an entire bike. However, its age-related weaknesses such as potential brittleness, part scarcity, and maintenance requirements mean it requires careful handling and may not be ideal for high-performance or heavy-use applications without upgrades.

If your priority is preserving the original character of the KX80 or completing a restoration project, this part is a worthwhile investment. If you re looking for a durable, high-performance component, you may need to supplement it with modern upgrades (e.g., a high-flow filter or breather system) to ensure reliability and efficiency.

- **Buy if:** You are restoring a KX80, prioritize authenticity, or need a specific part for a project bike and can source compatible spares. Ensure the air box is clean, intact, and free of cracks before use.

- **Avoid if:** You plan to ride the bike aggressively without modifications, cannot commit to maintenance, or prefer modern, high-performance components.

- **Consider upgrading later:** If you decide to keep the bike long-term, evaluate whether a modern air filter or breather system would improve reliability and performance.

For best results, pair this purchase with a thorough inspection and cleaning of the air box, and be prepared to source replacement parts as needed.
