**Pros and Cons of Buying a Honda 16017-MCJ-003 (CBR900RR AC 2000-01 Throttle Body, Starter Shaft Set, NOS)**
### **Pros:**1. **Direct OEM Replacement** This part is a genuine Honda aftermarket (HMA) or NOS (New Old Stock) component, ensuring compatibility with the 2000-01 CBR900RR AC models. It matches the factory specifications, reducing the risk of fitment issues or performance problems.
2. **Improved Performance Potential** The throttle body and starter shaft are critical components that can affect throttle response and engine starting. A fresh or high-quality NOS part may offer smoother operation, better throttle control, and more reliable starting compared to worn-out original parts.
3. **Reliability and Durability** NOS parts are often sourced from high-mileage but well-maintained vehicles, meaning they have already been tested under real-world conditions. If properly stored, they should retain good structural integrity and performance.
4. **Cost-Effective Alternative to New Parts** While not brand-new, NOS parts are typically cheaper than brand-new OEM replacements from Honda. This makes them a budget-friendly option for restorations or maintenance without sacrificing quality.
5. **Easier Availability** Some NOS parts may be easier to source than new OEM components, especially for older model bikes, reducing wait times for repairs or upgrades.
6. **Potential for Increased Resale Value** If you re restoring a classic bike, using NOS or high-quality aftermarket parts can enhance its authenticity and appeal to collectors, potentially increasing its resale value.

### **Cons:**1. **Age and Wear** Even if the part is NOS, it may still show signs of wear, such as minor corrosion, slight pitting, or reduced responsiveness in the throttle body. This could lead to inconsistent performance or the need for additional cleaning or refurbishing.
2. **Condition Uncertainty** Unlike new parts, you cannot guarantee the exact condition of NOS components. Some may have been exposed to moisture, oil contamination, or improper storage, which could affect longevity or functionality.
3. **Limited Warranty or No Warranty** NOS parts often come without a warranty, unlike new OEM parts. If the component fails prematurely, you may be responsible for replacement costs.
4. **Potential for Counterfeit Parts** There is a risk of purchasing fake NOS parts, especially from untrusted sellers. These may not fit properly, perform poorly, or even damage your bike if installed incorrectly.
5. **Mixed Quality** The quality of NOS parts can vary depending on the source. Some may be in excellent condition, while others could be salvage-grade, requiring extensive refurbishing before use.
6. **Environmental Concerns** NOS parts are not eco-friendly, as they come from dismantled vehicles. If you prioritize sustainability, this may be a drawback.
7. **Installation Challenges** If the part is significantly worn or corroded, installation may require additional cleaning, machining, or replacement of related components (e.g., seals, gaskets), adding to labor costs.

### **Conclusion:**Buying a **Honda 16017-MCJ-003 throttle body and starter shaft set (NOS)** for your 2000-01 CBR900RR AC can be a practical and cost-effective solution if you prioritize compatibility, performance, and authenticity. The NOS option offers a balance between quality and affordability, especially for restorations or maintenance projects where new parts are not necessary.
However, the trade-offs such as potential wear, lack of warranty, and uncertainty in condition mean you must carefully inspect the parts upon receipt and be prepared for possible refurbishing. If budget allows, a new OEM or high-quality aftermarket replacement (e.g., from reputable brands like Honda Performance Parts or reputable third-party manufacturers) may offer peace of mind with better warranties and guaranteed condition.
For most riders, **NOS parts are a reasonable choice** if sourced from a trusted seller and inspected thoroughly. If you re restoring a bike for show or planning long-term use, consider investing in new or refurbished parts to ensure optimal reliability.
