Review MOOSE Honda Jet Kit New fits TRX450 2004–2005

The **Moose MQ107 2004-2005 Honda TRX450 Jet Kit (Part #1007-0089)** is a meticulously engineered aftermarket upgrade designed to transform the stock fuel system of your Honda TRX450R into a high-performance, jet-assisted injection setup. This kit is specifically tailored for the 2004 and 2005 model years, ensuring compatibility with the TRX450R s unique fuel delivery requirements while maximizing throttle response, power, and reliability. At its core, the MQ107 kit replaces the stock fuel pump and injectors with a pair of high-flow, precision-machined **Moose Performance injectors**, which deliver a more consistent and optimized fuel spray pattern directly into the intake ports. These injectors are paired with a **high-capacity Moose fuel pump**, engineered to maintain steady fuel pressure even under heavy load, eliminating the common issues of fuel starvation or inconsistent delivery that plague stock systems. The kit also includes a **dedicated fuel rail and mounting hardware**, ensuring a clean, leak-free installation with minimal modifications to the stock engine bay. For added refinement, the MQ107 features a **Moose jet kit**, which includes precision-machined jets that fine-tune the air-fuel mixture for optimal combustion, reducing backpressure and improving overall engine efficiency. Whether you're tackling rough terrain, pushing the limits in the trails, or simply seeking a more responsive ride, this kit delivers a noticeable boost in power and smoothness without compromising the TRX450R s legendary durability. Built to Moose s signature standards of quality and performance, the MQ107 is an ideal choice for riders looking to enhance their TRX450R s fuel delivery system while maintaining ease of installation and long-term reliability.

### Pros and Cons of Buying a Moose MQ107 (2004-2005) Honda TRX450 with a Jet Kit (Part #1007-0089)

#### **Pros:**

1. **Reliability and Durability** The Honda TRX450 is widely regarded as one of the most dependable ATVs ever made. Its robust engine, simple design, and high-quality components make it a long-lasting machine, especially when properly maintained.

2. **Strong Engine Performance** The 450cc parallel-twin engine produces around 35-40 horsepower, which is more than sufficient for most off-road tasks, including hauling light loads, pulling trailers, and handling rough terrain. The jet kit (1007-0089) is designed to improve fuel efficiency and reduce emissions while maintaining power, making it a good upgrade for older models.

3. **Versatility** The TRX450 is built for utility work, including farming, construction, and recreational use. Its durable frame, high ground clearance, and strong suspension make it suitable for a wide range of applications.

4. **Ease of Maintenance** Compared to modern ATVs, the TRX450 is relatively simple to service. Many parts are easy to access, and the engine is known for its longevity with basic upkeep (oil changes, air filter cleaning, etc.).

5. **Resale Value and Availability of Parts** Due to its popularity and longevity, the TRX450 has a strong used market, and replacement parts are widely available. The jet kit (1007-0089) is an official Honda part, ensuring compatibility and ease of installation.

6. **Off-Road Capability** The TRX450 is built for rough terrain, with features like a high-lift suspension, durable tires, and a rugged frame. It handles well in mud, sand, and rocky conditions, making it ideal for off-road enthusiasts or those who need a workhorse ATV.

7. **Fuel Efficiency (Post-Jet Kit Upgrade)** The jet kit is designed to optimize fuel delivery, which can improve fuel efficiency and reduce emissions compared to the stock carburetion. This makes the ATV more economical to operate, especially if you use it frequently.

8. **Low Operating Costs** Honda s reputation for reliability translates to lower long-term costs. The TRX450 requires fewer repairs and less frequent maintenance than many modern ATVs, making it a cost-effective choice over time.

9. **Classic Design Appeal** For those who appreciate older, simpler machines, the TRX450 has a timeless design that many find appealing. It lacks the complexity of modern electronics, which can be a plus for some users.

10. **Off-Road Community Support** The TRX450 has a dedicated following, with many online forums and communities (e.g., Honda TRX450 forums, ATV enthusiast groups) where owners share tips, modifications, and troubleshooting advice.

#### **Cons:**

1. **Age and Wear** The 2004-2005 model is nearly 20 years old, which means it may have accumulated significant mileage or wear. If the ATV hasn t been well-maintained, you could inherit hidden issues like worn bearings, clutch problems, or engine wear.

2. **Outdated Technology** The TRX450 lacks modern features such as electronic fuel injection (EFI), traction control, or advanced suspension systems found in newer ATVs. This can limit its performance in certain conditions or make it feel less refined compared to modern models.

3. **Fuel Efficiency Limitations** While the jet kit improves efficiency, the TRX450 still consumes fuel at a higher rate than many modern ATVs. If you use it frequently for long hours, fuel costs may add up.

4. **Weight** The TRX450 is heavier than some modern ATVs, which can make it less nimble in tight or technical terrain. Its weight also contributes to higher fuel consumption and wear on components over time.

5. **Limited Aftermarket Support** While the TRX450 has a strong following, aftermarket parts and modifications are not as extensive as those for newer ATVs. Some modern upgrades (e.g., suspension kits, exhaust systems) may not be compatible or widely available.

6. **Emissions Compliance** The jet kit (1007-0089) helps meet emissions standards for its era, but if you plan to use the ATV in areas with strict emissions regulations, you may still face challenges. Some states or regions have phased out older models due to emissions concerns.

7. **Rust and Corrosion** Older ATVs, especially those exposed to harsh environments (salt, mud, water), are prone to rust. Inspect the frame, undercarriage, and suspension components carefully for signs of rust or structural weakness.

8. **Clutch and Transmission Wear** The TRX450 s clutch and transmission are known to wear out over time, especially if the ATV is used for heavy-duty tasks. Replacing the clutch or transmission can be expensive, and the process is labor-intensive.

9. **Limited Comfort for Long Use** The ergonomics of the TRX450 are basic compared to modern ATVs. The seat is firm, the controls are less refined, and the lack of suspension travel can make long rides uncomfortable.

10. **Resale Depreciation** While the TRX450 holds its value better than many ATVs, it will still depreciate over time. If you plan to upgrade later, the resale value may not justify the initial purchase price for a used model.

11. **No Automatic Transmission Option** The TRX450 only comes with a manual transmission, which can be less convenient for some users, especially those who prefer automatic transmissions in modern ATVs.

12. **Potential for Hidden Issues** Without a thorough inspection or service history, you may inherit problems like:

- Worn out bearings or bushings.

- Leaking seals or hoses.

- Engine misfires or carburetion issues (even with the jet kit).

- Electrical gremlins (e.g., faulty starter, ignition problems).

---

### **Ending Conclusion:**

The **Moose MQ107 (2004-2005) Honda TRX450 with a jet kit (1007-0089)** is an excellent choice if you prioritize **reliability, durability, and off-road capability** over modern conveniences. It s a proven workhorse that excels in utility tasks, farming, and rough-terrain use. The jet kit is a worthwhile upgrade for better fuel efficiency and emissions compliance, making it a more practical option for daily or frequent use.

However, if you re looking for **modern features, fuel efficiency, or comfort**, the TRX450 may feel outdated. Its age also means you ll need to be diligent about maintenance and inspection to avoid costly repairs. That said, for those who appreciate a no-nonsense, high-performance ATV that can handle almost anything, the TRX450 remains a top-tier choice.

- You plan to use it **heavily in extreme conditions** (e.g., deep mud, heavy loads) without regular maintenance.

- You re sensitive to **noise, vibration, or lack of refinement**.

- You can t afford **potential repair costs** for worn-out components (clutch, bearings, etc.).
