Review YAMAHA 1986 87 Wire Harness Cdi Voltage Regulator Wires Used Oem fits TT350 1986-87

The **Yamaha 2GK-85540-20-00 wire harness, CDI (Capacitive Discharge Ignition) voltage regulator, and ignition wires** for the **1986-1987 TT350** motorcycle represent a meticulously engineered set of components designed to ensure reliable, high-performance ignition and electrical functionality. This genuine Yamaha assembly is crafted to meet the exact specifications of the TT350 s dual-spark ignition system, delivering precise timing and consistent power delivery to the engine s cylinders. The **wire harness** is built with durable, heat-resistant materials to withstand the harsh conditions of motorcycle operation, featuring properly insulated conductors that minimize signal interference and voltage drop, ensuring optimal performance under varying riding conditions. The **CDI module** within this assembly is a critical component, responsible for generating the high-voltage pulses required to ignite the fuel-air mixture in the combustion chamber with pinpoint accuracy, enhancing combustion efficiency and overall engine responsiveness. Paired with the **voltage regulator**, this system maintains a stable electrical output, protecting sensitive electronics while providing the necessary voltage to the ignition system and other electrical accessories. The **ignition wires**, specifically designed for the TT350, are constructed with high-quality silicone rubber insulation and reinforced copper conductors to prevent degradation from oil, heat, and vibration, ensuring long-lasting reliability. Together, these components form a cohesive and robust electrical system that not only meets but exceeds the original equipment manufacturer s standards, offering motorcycle enthusiasts and restorers a trustworthy solution for maintaining or reviving the performance and longevity of their classic TT350. Whether used in a restoration project or as a replacement for worn-out parts, this assembly guarantees seamless integration with the bike s electrical architecture, delivering the power and precision needed for a smooth and exhilarating ride.

### **Pros and Cons of buying a Yamaha TT350 Wire Harness, CDI, and Voltage Regulator (Part Numbers: 2GK-85540-20-00, 1986-87 Models)**

#### **Pros:**

1. **Compatibility** These components are designed specifically for the 1986-87 Yamaha TT350, ensuring a proper fit without modification.

2. **Reliability** Yamaha s electrical systems, including the CDI (Capacitor Discharge Ignition) and voltage regulator, are known for durability when sourced from genuine or high-quality aftermarket suppliers.

3. **Performance Stability** A functioning CDI and voltage regulator ensure consistent ignition timing and stable electrical output, preventing misfires, stalling, or electrical gremlins.

4. **Prevents Further Damage** If your bike s original components are failing, replacing them early can avoid secondary issues like battery drain, wiring shorts, or starter motor failure.

5. **Cost-Effective Long-Term Fix** While the upfront cost may seem high, replacing worn-out electrical parts extends the life of your bike and avoids more expensive repairs down the line.

6. **Easier Maintenance** If you re restoring or rebuilding the bike, having these components in good condition simplifies troubleshooting and ensures a smoother build process.

7. **Aftermarket Availability** Even if you can t find exact OEM parts, many aftermarket suppliers offer compatible replacements that meet the same specifications.

#### **Cons:**

1. **Age of Parts** If the original parts are from a 1986-87 model, they may have been sitting in storage for decades, potentially degrading over time. Inspect for dry-rotted wiring, cracked casings, or corroded terminals.

2. **Limited Availability** Genuine OEM parts for older Yamaha models can be hard to find, especially from authorized dealers. You may need to source from specialty motorcycle parts suppliers or eBay, which could involve shipping risks.

3. **Cost** Depending on the supplier, these components may be priced higher than expected, especially if they are new OEM replacements rather than used or refurbished units.

4. **Installation Complexity** If you re not experienced with motorcycle electrical work, wiring harness repairs or CDI/voltage regulator replacements can be tricky, requiring careful soldering, terminal connections, and testing.

5. **Counterfeit Risk** If purchasing from untrusted sellers, there s a chance of receiving fake or low-quality parts that fail prematurely.

6. **Compatibility with Modifications** If your bike has aftermarket modifications (e.g., performance exhaust, custom wiring), these stock components may not integrate perfectly without adjustments.

7. **Testing Required** Even new parts may need testing to ensure they function correctly, which could involve additional tools (multimeter, ignition tester) and troubleshooting time.

### **Conclusion**

Buying the **Yamaha TT350 wire harness, CDI, and voltage regulator** (1986-87 models) is a **wise investment** if your bike is experiencing electrical issues like misfires, no-start conditions, or battery drain. These components are critical to the bike s ignition and charging system, and replacing them can restore reliability and prevent further damage.

However, the decision should be based on **availability, condition, and your technical comfort level**. If you re restoring a classic bike, prioritize **genuine or high-quality aftermarket parts** to avoid compatibility issues. If you re unsure about installation, consider consulting a mechanic or seeking detailed wiring diagrams before proceeding.

For most riders, **the long-term benefits outweigh the costs**, especially if the bike is a cherished project or a daily rider. Just ensure you **inspect the parts upon arrival** and **test them thoroughly** after installation to confirm they re functioning correctly.

### **Recommendation:** - **If your bike has confirmed electrical failures (CDI, voltage regulator, or wiring issues):**

- **Buy from a reputable supplier** (e.g., Yamaha Parts Center, Speedhawk, or trusted eBay sellers with positive reviews).

- **Check for used/refurbished options** if new parts are too expensive, but verify their condition.

- **Consider a full electrical system overhaul** if multiple components are failing simultaneously.

- **Document the installation process** and test the bike thoroughly post-installation.

- **If you re unsure about symptoms or installation:**

- **Get a professional diagnosis** before purchasing parts to avoid buying unnecessary components.

- **Learn basic motorcycle electrical troubleshooting** (e.g., checking for spark, testing voltage regulator output) before attempting repairs.

- **For long-term reliability:**

- **Pair these replacements with a new battery and clean wiring connections** to prevent future electrical gremlins.

- **Keep spare fuses and connectors** on hand for future maintenance.

Ultimately, **replacing these components is a smart move for restoring your TT350 s functionality**, but **proper sourcing and installation are key to success**.
