### Pros and Cons of buying a Celox AC2365CA113JI Carburetor for a Yamaha QT50 (1979 1987)

#### **Pros:**

1. **Compatibility** The Celox AC2365CA113JI is designed as a direct replacement for the stock carburetor on Yamaha QT50 models from 1979 to 1987, ensuring a straightforward installation without major modifications.

2. **Improved Performance** Celox carburetors are known for better fuel efficiency and smoother throttle response compared to stock units, which can be prone to clogging or inconsistent idle.

3. **Durability** Celox carburetors are constructed with higher-quality materials, reducing the likelihood of internal wear or leaks over time, which is common with original OEM parts after decades of use.

4. **Easier Maintenance** The design often allows for simpler cleaning and adjustment compared to older, more complex carburetors, making it easier for owners to maintain optimal performance.

5. **Cost-Effective Upgrade** While not a high-performance racing carburetor, it offers a reasonable balance between cost and improved reliability, making it a practical choice for daily riding.

6. **Availability of Parts** Celox is a well-known brand with a strong aftermarket presence, meaning replacement parts (jets, gaskets, etc.) are widely available if needed.

7. **Reduced Fuel Consumption** Many users report better fuel economy with Celox carburetors, which can be particularly noticeable on older, less efficient engines.

#### **Cons:**

1. **Potential Learning Curve** If the owner is unfamiliar with carburetor tuning, adjustments may require some trial and error to achieve the best balance between power and smoothness.

2. **Initial Cost** While still affordable compared to OEM replacements, a Celox carburetor is more expensive than a used or salvaged OEM unit, which might appeal to budget-conscious buyers.

3. **Not a High-Performance Solution** This is not a performance carburetor; it is primarily an upgrade for reliability and efficiency rather than raw power. Riders seeking significant horsepower gains would need a different solution.

4. **Requires Proper Installation** Improper installation (e.g., incorrect gasket placement, misaligned jets) can lead to leaks, poor performance, or even engine damage. Professional installation is recommended if the owner lacks experience.

5. **Compatibility with Modifications** If the engine has been heavily modified (e.g., crankshaft, pistons, or camshaft upgrades), the stock displacement may no longer match the carburetor s flow rate, potentially causing rich/lean issues.

6. **Limited Longevity Claims** While Celox carburetors are durable, they are not indestructible. Heavy use or neglect can still lead to wear over time, though less so than OEM units.

7. **Potential for Aftermarket Parts Issues** Some users report inconsistencies in aftermarket parts (e.g., jets, gaskets) from different suppliers, which could complicate maintenance.

---

### **Conclusion:**

The Celox AC2365CA113JI carburetor is a solid, practical choice for Yamaha QT50 owners looking to replace a worn-out or inefficient stock carburetor. It offers noticeable improvements in reliability, fuel efficiency, and ease of maintenance without requiring extensive modifications. However, it is not a high-performance part and may require some adjustment to optimize performance. For riders who prioritize longevity, simplicity, and a cost-effective upgrade over raw power, this carburetor is a strong recommendation.

### **Recommendation:**

If you are replacing a failing stock carburetor on your Yamaha QT50 (1979 1987), the Celox AC2365CA113JI is a **highly recommended upgrade**. Ensure you:

- Purchase from a reputable seller to avoid counterfeit or damaged units.

- Follow the installation instructions carefully, preferably with the help of a mechanic if unfamiliar with carburetor work.

- Adjust the carburetor gradually (idle, mixture, and throttle response) to achieve the best balance.

- Keep spare jets and gaskets on hand for future maintenance.

For riders who plan to modify the engine significantly, consider consulting with an expert to ensure the carburetor remains compatible with any upgrades. Otherwise, the Celox is an excellent choice for restoring and improving your QT50 s performance.
