### **Pros and Cons of buying a Yamaha XS850L Mid-Special Street Tachometer Cable (Model: Motion Pro 7777-AL385278-91, Fits 1980-1981)**
#### **Pros:**1. **Compatibility** The cable is specifically designed for the 1980-1981 Yamaha XS850L, ensuring a proper fit without modification. This reduces the risk of installation errors that could damage the tachometer or wiring harness.
2. **Quality Construction** Motion Pro is a reputable brand known for producing reliable aftermarket automotive parts, including wiring harnesses and cables. The cable is likely built to withstand regular use without excessive wear or failure.
3. **Easy Installation** As a direct replacement, the cable should be straightforward to install, requiring minimal tools and technical skill. This makes it a practical choice for both experienced mechanics and DIY enthusiasts.
4. **Prevents Common Issues** Many vintage bikes suffer from degraded or damaged wiring over time. Replacing the tachometer cable can resolve intermittent tachometer readings, flickering gauges, or complete failure, improving the bike s reliability.
5. **Cost-Effective Fix** Replacing a faulty cable is far cheaper than repairing or replacing a damaged tachometer unit or wiring harness. It s a simple, low-risk upgrade that can save money in the long run.
6. **Maintains Original Functionality** The cable is designed to replicate the original factory specifications, ensuring the tachometer operates as intended without altering the bike s performance or appearance.
7. **Availability of Parts** Since this is a common part for the XS850L, finding replacements or additional wiring components should be relatively easy if needed in the future.

#### **Cons:**1. **Age of the Bike** The 1980-1981 XS850L is a classic, and while the cable itself may be reliable, other components (such as the tachometer unit, wiring loom, or ground connections) could be worn out or corroded. Replacing just the cable may not fully resolve electrical issues if other parts are failing.
2. **Potential for Counterfeit or Low-Quality Replacements** While Motion Pro is a trusted brand, there is a risk of purchasing a counterfeit or inferior copy, especially if buying from unverified sellers. Always verify the seller s reputation and product authenticity.
3. **Limited Customization** This is a direct replacement part, meaning it won t offer any performance or aesthetic upgrades beyond fixing the tachometer function. If you re looking for modifications (e.g., LED gauges, digital upgrades), this cable alone won t suffice.
4. **Possible Compatibility Quirks** Even if the cable fits physically, there may be subtle electrical differences (e.g., pinout, grounding) that could cause issues if the bike s wiring has been previously modified or if the tachometer unit is damaged.
5. **No Warranty on Used Parts** If purchasing from a third-party seller (e.g., eBay, Facebook Marketplace), the cable may not come with a warranty. Motion Pro s official dealers typically offer warranties, so buying directly from an authorized source is ideal.
6. **Installation Challenges** While the installation is usually simple, if the bike s wiring harness is damaged or corroded, additional work may be required to ensure a clean connection. This could extend the time or cost of the repair.
7. **Opportunity Cost** If the tachometer itself is failing or the wiring loom is degraded, replacing just the cable may be a temporary fix. A more comprehensive repair (e.g., replacing the entire wiring harness or tachometer) might be necessary sooner than expected.

### **Conclusion:**The **Motion Pro 7777-AL385278-91 tachometer cable** is a **practical and cost-effective solution** for restoring or maintaining the tachometer function on a 1980-1981 Yamaha XS850L. It offers a direct replacement with minimal risk, making it ideal for riders who need a quick, reliable fix without major modifications. However, it is not a comprehensive repair other components (e.g., tachometer unit, wiring loom, grounds) should be inspected to ensure the issue is fully resolved.
If the bike s electrical system is otherwise in good condition, this cable will likely serve its purpose well. For long-term reliability, consider pairing this replacement with a thorough inspection of the wiring harness and tachometer unit.

### **Recommendation:**- **Buy from an authorized Motion Pro dealer or a trusted seller** to ensure authenticity and warranty coverage.
- **Inspect the tachometer unit and wiring loom** before and after installation to confirm no other issues exist.
- **Test the tachometer thoroughly** after installation, ensuring it reads accurately at idle, mid-range, and high RPMs.
- **Consider upgrading the wiring loom or tachometer** if the bike is being restored or modified extensively, as these components may degrade over time.
- **Document the installation** for future reference, especially if the bike is being sold or worked on by others.
**Final Verdict:** This cable is a **solid, low-risk purchase** for fixing a tachometer cable issue on the XS850L. Proceed with confidence if the rest of the electrical system is in good shape.
