Review HONDA Trx350fuel Tank Breather Line Hoses fits FOURTRAX FOREMAN TRX350 1986–1989

The **Honda 17632-HA7-670 Fuel Tank Breather Line and Hoses Assembly** is a meticulously engineered replacement component designed specifically for the **1986 1989 Honda FourTrax Foreman TRX350**, ensuring optimal performance, reliability, and longevity for this rugged off-road utility vehicle. This high-quality aftermarket assembly replaces the original fuel system components, including the **breather line and associated hoses**, which are critical for maintaining proper fuel pressure, preventing vapor lock, and reducing engine strain during demanding off-road use. Crafted from durable, fuel-resistant materials, these hoses are built to withstand extreme temperatures, harsh chemical exposure, and the constant flexing of off-road terrain, minimizing the risk of leaks, cracks, or premature failure. The **breather line** plays a vital role in regulating fuel tank pressure, allowing air to escape as fuel is drawn from the tank while preventing a vacuum from forming, which could restrict fuel flow and impair engine efficiency. By upgrading to this **OEM-compatible or improved aftermarket assembly**, owners of the TRX350 can eliminate common fuel system issues such as clogging, fuel starvation, or excessive vapor buildup, particularly in high-altitude or hot-climate conditions. Whether used for daily utility work, serious off-roading, or extended storage, this **direct-fit replacement** ensures a seamless upgrade without the need for modifications, providing peace of mind and enhanced performance for years of dependable service. Ideal for both restoration projects and routine maintenance, this component is a straightforward yet essential upgrade for anyone seeking to maintain the peak condition of their Honda FourTrax Foreman.

### **Pros and Cons of Buying a 1986-1989 Honda FourTrax Foreman TRX350 with the Mentioned Fuel Tank Breather Line Hoses**

#### **Pros**

1. **Classic Reliability** Honda s FourTrax Foreman TRX350 is known for its durable engine and solid build quality, making it a dependable off-road machine even decades later. Many owners report that with proper maintenance, these bikes can last for hundreds of thousands of miles.

2. **Off-Road Capability** The TRX350 was designed for rugged terrain, featuring a sturdy frame, long-travel suspension (for its time), and a powerful 349cc single-cylinder engine capable of handling rough trails. Its lightweight aluminum frame also makes it nimble compared to heavier modern ATVs.

3. **Simplicity and Repairability** Being an older model, parts are widely available, and mechanics familiar with classic Hondas can easily diagnose and fix issues. The engine and drivetrain are straightforward, reducing complexity in maintenance.

4. **Lower Purchase Price** Compared to newer ATVs, the TRX350 is significantly cheaper, making it an attractive option for budget-conscious buyers. This also means more money can be allocated toward modifications or repairs.

5. **Modification Potential** The TRX350 has a strong aftermarket presence, with upgrades available for suspension, exhaust, engine tuning, and more. This allows owners to customize the bike to suit their riding style or terrain.

6. **Fuel Efficiency** The 350cc single-cylinder engine is relatively fuel-efficient for its class, especially when ridden lightly. It consumes less gas than larger modern ATVs, which can be cost-effective for casual or weekend riders.

7. **Nostalgia and Community** Owning a classic Honda ATV connects you to a community of enthusiasts who share tips, modifications, and restoration projects. This can be rewarding for those who appreciate vintage machinery.

8. **Lightweight and Maneuverable** At around 400 450 lbs (depending on modifications), the TRX350 is easier to handle than heavier modern ATVs, making it ideal for tight trails or solo riding.

#### **Cons**

1. **Age-Related Wear and Tear** The 1986 1989 models are approaching 40 years old, meaning critical components like the engine, transmission, and suspension may require significant attention. Rust, worn bearings, and outdated seals are common issues.

2. **Fuel Tank Breather Line Hoses (Specific Concern)** The fuel tank breather line hoses on these models can degrade over time, leading to fuel leaks, clogs, or even fire hazards if they crack or become brittle. Replacing them is a necessary maintenance task and should be done proactively.

- **Why it matters**: A failing breather line can cause fuel to seep into the engine bay, creating a slippery and potentially flammable environment. It can also restrict airflow, leading to poor engine performance or stalling.

3. **Outdated Safety Features** Modern ATVs come with roll cages, better brakes, and improved suspension for safety. The TRX350 lacks these advancements, making it riskier in high-speed or rough-terrain riding.

4. **Limited Modern Comfort** Ergonomics, seating, and controls are less refined compared to today s ATVs. Long rides can be uncomfortable, and the lack of modern suspension tuning may make rough trails harsher.

5. **Emissions and Legal Restrictions** Some areas have restrictions on older, unmodified ATVs due to emissions standards. You may need to modify the bike (e.g., with a catalytic converter or EGR system) to comply with local laws, adding cost and complexity.

6. **Part Availability Challenges** While parts are still available, some original components (e.g., specific hoses, gaskets, or electrical parts) may be hard to find or require sourcing from specialty vendors. Replicas or aftermarket parts may not fit perfectly.

7. **Higher Maintenance Costs** Older engines and drivetrains require more frequent maintenance than modern counterparts. You ll need to budget for regular tune-ups, chain adjustments, and potential rebuilds.

8. **Resale Value** Unlike newer ATVs, the TRX350 s resale value is minimal. If you plan to upgrade later, you may not recoup much of your initial investment.

9. **Fuel and Lubricant Compatibility** Older engines are sensitive to modern fuel additives and synthetic oils. Using the wrong lubricants can lead to premature wear or damage. You may need to source vintage-grade fuel or oils.

10. **Rust and Corrosion** If the bike has been stored improperly, rust can compromise the frame, suspension, and other metal components. A thorough inspection and restoration may be required before safe use.

### **Ending Conclusion**

The **1986 1989 Honda FourTrax Foreman TRX350** is a fantastic choice for riders who prioritize **reliability, off-road capability, and modification potential** while being willing to invest time and effort into maintenance. Its classic Honda engineering ensures durability, and its lightweight design makes it ideal for adventurous solo riders or those exploring vintage ATV culture.

However, **buying one with attention to the fuel tank breather line hoses (and other critical components) is non-negotiable**. A failing breather line poses serious safety risks, so replacing or repairing it should be your first priority. Beyond that, be prepared for **higher maintenance costs, age-related wear, and the need for patience** this is not a "plug-and-play" ATV. If you re comfortable with mechanical work and enjoy the challenge of restoring and maintaining a classic machine, the TRX350 can be an incredibly rewarding purchase.

For **casual riders, families, or those seeking a modern ATV**, newer models with better safety features, warranties, and convenience may be a better long-term investment. But for **enthusiasts, collectors, or off-road purists**, the TRX350 remains a legendary machine worth preserving.

### **Recommendation**

- You have mechanical skills or access to a trusted mechanic to handle maintenance.

- You re willing to invest time in restoring and upgrading the bike (especially the fuel system, suspension, and drivetrain).

- You prioritize **off-road performance, nostalgia, or modification potential** over modern convenience.

- You plan to use it **lightly or for short-term projects** (e.g., trail riding, club events) rather than daily commuting.

**Avoid or reconsider if:**

- You re not prepared for **higher upfront costs** (e.g., replacing hoses, seals, or worn components).

- You live in an area with **strict emissions laws** that may require costly modifications.

- You re not comfortable with **older fuel and lubricants** or the risk of rust/deterioration.

**Final Step Before Purchase:**

- **Inspect the fuel tank breather line hoses thoroughly** replace them immediately if they show signs of cracking, brittleness, or leaks.

- **Budget for a full service**, including chain adjustment, valve clearance check, and fluid changes.
