Review SUZUKI Oil Pump Drive Shaft Oem Motorcycle fits GT250 1974

The **Suzuki 16320-18000 Oil Pump Drive Shaft** is a precision-engineered component designed exclusively for the **1974 Suzuki GT250**, a classic motorcycle known for its lightweight frame, nimble handling, and timeless performance. This drive shaft serves as a critical link between the engine s oil pump and the transmission, ensuring a steady and reliable supply of lubrication to the engine s internal components while maintaining optimal operating temperatures. Crafted from high-grade steel, this shaft is built to withstand the demands of high-revving two-stroke engines, delivering smooth and consistent power transfer without excessive wear or vibration. The design incorporates a **splined connection** at one end to securely interface with the oil pump s drive gear, while the opposite end features a **precision-machined shaft** that aligns seamlessly with the transmission s input mechanism, minimizing friction and maximizing efficiency. Whether you're restoring a vintage GT250 to its original glory or upgrading an existing build, this OEM-quality drive shaft ensures that your engine remains properly lubricated, reducing the risk of premature failure and extending the lifespan of critical components. Its compatibility with the 1974 model year makes it an essential replacement part for enthusiasts seeking to preserve the authenticity and performance of their Suzuki, while its robust construction guarantees durability for countless miles of riding. Proper installation requires careful alignment and secure fastening to prevent slippage or misalignment, which could lead to oil pump failure or transmission issues making this part a small but vital investment in your motorcycle s long-term reliability.

### Pros and Cons of Buying a Used Suzuki 16320-18000 Oil Pump Drive Shaft for a 1974 Suzuki GT250

#### **Pros:**

1. **Cost-Effective Solution** Purchasing a used or aftermarket oil pump drive shaft is significantly cheaper than buying a new OEM part, especially for a classic motorcycle like the GT250. This can save hundreds of dollars compared to a brand-new replacement.

2. **Easier Availability** Since the GT250 is an older model, finding a genuine OEM part may be difficult or require sourcing from specialty suppliers. Used or aftermarket alternatives are more widely available, often through online marketplaces, classic bike forums, or specialty shops.

3. **Compatibility with Modifications** If you ve modified your GT250 (e.g., upgraded engine, different crankshaft, or aftermarket oil pumps), a used or aftermarket drive shaft may be necessary to ensure proper fitment and functionality.

4. **Budget-Friendly Restoration** For enthusiasts restoring a classic bike, a used part allows for a more affordable rebuild without sacrificing performance or reliability, assuming the part is in good condition.

5. **Potential for Customization** Some aftermarket drive shafts may offer slight performance improvements or better durability, depending on the material and design. This can be beneficial if you re pushing the engine harder than stock.

---

#### **Cons:**

1. **Uncertain Condition and Lifespan** Used parts may have hidden wear, cracks, or damage that isn t immediately visible. A worn or damaged drive shaft could lead to oil pump failure, engine damage, or premature wear on other components.

2. **Lack of Warranty or Guarantee** Unlike new OEM or reputable aftermarket parts, used parts typically come with no warranty. If the part fails shortly after installation, you may be left without recourse.

3. **Potential Fitment Issues** Even if the part is listed as compatible, slight variations in manufacturing or wear on your specific GT250 could cause misalignment or improper function. This may require additional machining or adjustments.

4. **Quality Variability** The quality of used or aftermarket parts can vary widely. Some may be well-maintained and reliable, while others could be salvaged from a poorly maintained bike, leading to reliability concerns.

5. **Risk of Counterfeit or Mismatched Parts** On platforms like eBay or Facebook Marketplace, there s a risk of receiving a part that isn t actually for your model or is a low-quality knockoff. Always verify the part s authenticity and compatibility before purchasing.

6. **Installation Challenges** If you re not experienced with motorcycle engine work, installing a drive shaft may require specialized tools, patience, and precision. Improper installation could lead to further damage or failure.

7. **Limited Long-Term Reliability Data** Unlike a new part with documented performance, a used drive shaft s long-term reliability is unknown. It may work fine for years or fail unexpectedly, depending on its history.

---

### **Conclusion:**

Buying a used or aftermarket Suzuki oil pump drive shaft for your 1974 GT250 can be a practical and cost-effective choice, especially if you re working within a tight budget or restoring a classic bike. However, the risks of quality, fitment, and reliability must be carefully considered. If possible, opt for a part from a trusted seller with a clear history, inspect it thoroughly (or have a mechanic do so), and consider testing it for smooth operation before full installation.

For maximum peace of mind, if budget allows, a new OEM or high-quality aftermarket part from a reputable supplier (such as Suzuki s parts department or a specialty classic bike shop) is the safest option. If you proceed with a used part, prioritize condition, compatibility, and seller reputation to minimize risks.

### **Recommendation:**

- **If you re confident in your mechanical skills and the part s condition**, a used drive shaft can be a viable and budget-friendly solution.

- **If reliability and longevity are priorities**, invest in a new or high-quality aftermarket part to avoid potential future issues.

- **Always inspect the part closely** (look for cracks, wear, or damage) and test it for smooth operation before installing it in your GT250.

- **Consult with a mechanic or classic bike forum** to verify compatibility and get advice on installation.

- **Consider purchasing from a seller with a return policy or warranty** to protect yourself in case of issues.
