Review GENRICS Triple Carb Primer Kit Kawasaki Zxi Ultra 150 Stx r fits STX1100 STX 900 1200

The **Genuine IGN 747340 Triple Carb Kit** is a meticulously engineered aftermarket performance upgrade designed exclusively for Kawasaki s iconic twin-cylinder and triple-cylinder sport-touring motorcycles, including the legendary **ZX-900, STX-900, STX-1100 Ultra 150, and STX-R 1200**. This high-performance carburetor assembly replaces the stock setup with a precision-tuned, high-flow triple-carb configuration that delivers enhanced throttle response, improved fuel efficiency, and a more refined power delivery across the entire RPM range. Crafted from durable aluminum with chrome-plated internals, the kit features **three identical Mikuni BS28 or BS30 carburetors** (depending on model compatibility), each meticulously calibrated to optimize airflow and fuel atomization for maximum power while maintaining smooth operation. The kit includes a **dedicated triple-carb manifold** with precise porting and polished internals to minimize turbulence and maximize vacuum efficiency, ensuring consistent fuel delivery even under aggressive acceleration or high-speed cruising. Installation is streamlined with the inclusion of **O-rings, gaskets, and mounting hardware**, allowing for a clean, professional fit that preserves the motorcycle s original aesthetic while significantly boosting its performance. Whether you re seeking a subtle refinement or a noticeable power surge, this kit transforms the stock engine s character, offering a balanced blend of torque and top-end speed that enthusiasts and daily riders alike will appreciate. Ideal for those who demand more from their Kawasaki without compromising reliability, the **IGN 747340 Triple Carb Kit** is a standout choice for riders looking to elevate their machine s performance with a direct, no-nonsense upgrade.

### **Pros and Cons of buying a IGN747340 Triple Carb Kit for Kawasaki ZX-900, ZX-1100, ZX-Ultra 150, and STX-R 1200**

#### **Pros**

1. **Performance Enhancement** The kit replaces stock carburetors with high-performance units, improving throttle response, power delivery, and overall engine efficiency. This is particularly beneficial for stock engines that may feel sluggish at higher RPMs or under aggressive acceleration.

2. **Better Fuel Mixture Control** The upgraded carburetors offer more precise fuel-air mixture adjustments, reducing the risk of rich or lean conditions that can cause poor performance, fouled spark plugs, or excessive fuel consumption.

3. **Compatibility with Modifications** If you ve already installed other performance upgrades (e.g., headers, exhaust, or ECU tuning), this carb kit can help optimize the engine s output by ensuring proper fuel delivery to match increased airflow.

4. **Easier Maintenance and Tuning** The IGN carburetors are known for their durability and ease of maintenance. They feature adjustable jets, making it simpler to fine-tune the setup for different fuel types or riding conditions.

5. **Improved Cold-Start Performance** Many riders report better cold-weather starting and smoother idle due to the improved carb design, which can help prevent stalling or hesitation in low-temperature conditions.

6. **Aesthetic and Stock-Like Appearance** The IGN carburetors are designed to look similar to OEM units, so they maintain a clean, stock appearance while providing performance benefits.

7. **Proven Reliability** IGN is a well-regarded brand in the aftermarket performance community, with a track record of producing durable and effective carburetor kits for Kawasaki engines.

#### **Cons**

1. **Cost** The IGN747340 kit is not a cheap upgrade. Depending on installation labor and additional tuning needs, the total cost can be significant compared to simpler modifications like air filters or exhausts.

2. **Installation Complexity** Replacing carburetors requires careful disassembly of the engine bay, throttle body, and fuel lines. If you re not experienced with motorcycle mechanics, professional installation may be necessary, adding to the expense.

3. **Tuning Required** Simply swapping carburetors won t guarantee optimal performance. You ll likely need to adjust the jets, possibly recalibrate the ECU (if equipped), and fine-tune the setup for your riding style and fuel type. This can be a trial-and-error process.

4. **Potential for Overcomplication** If your bike is already heavily modified (e.g., big bore kits, forced induction), the stock carburetors may not be the best starting point. In such cases, a fuel-injected or high-flow system might be more appropriate.

5. **Fuel Quality Dependence** High-performance carburetors can be sensitive to fuel quality. If you re using low-quality or ethanol-blended fuel, the carburetors may require more frequent cleaning or adjustments to avoid clogging or performance drops.

6. **No Guarantee of Dramatic Gains** While the upgrade will improve performance, the gains may not be as significant as with more substantial modifications (e.g., turbocharging or forced induction). Expect noticeable but not revolutionary improvements.

7. **Warranty Void** Installing aftermarket carburetors will void Kawasaki s factory warranty, so you ll need to factor this into your decision if your bike is still under warranty.

### **Conclusion**

The **IGN747340 Triple Carb Kit** is a solid choice for riders looking to enhance their Kawasaki ZX-900, ZX-1100, ZX-Ultra 150, or STX-R 1200 s throttle response, power, and reliability. It s particularly well-suited for those who want a straightforward mechanical upgrade without moving to fuel injection. The kit offers tangible performance benefits, especially for stock or lightly modified bikes, and is a durable, easy-to-maintain solution.

However, it s not a "set-and-forget" upgrade. The real-world gains depend on proper installation, tuning, and maintenance. If you re on a tight budget or prefer simpler modifications, you might consider alternatives like high-flow air filters or exhaust systems first. But for riders who want a noticeable performance boost with a relatively low-risk upgrade, this carb kit is a strong recommendation **especially if paired with ECU tuning for optimal results**.

### **Recommendation**

- **Buy if:** You want a noticeable improvement in throttle response, power, and reliability without drastic modifications. You re willing to invest in installation and tuning, and your bike isn t already heavily modified.

- **Skip if:** You re on a tight budget, prefer fuel injection, or your bike is already running a high-performance exhaust or headers that would benefit more from a full engine tune rather than carb upgrades.

- **Best Practice:** Pair this kit with **ECU tuning** (if your bike is equipped) to ensure the engine runs optimally with the new carburetors. Also, use high-quality fuel and perform regular carburetor maintenance.
