### **Pros and Cons of Buying a 1986-1991 Yamaha 59V-95510-20 ATV (YFM225, No-Spark, Missing Mag Coil/Stator)**
#### **Pros**
1. **Classic and Reliable Design** The Yamaha 59V series (including the YFM225) is known for its durable, off-road-capable chassis and solid build quality. Many owners report that the basic mechanical components (engine block, transmission, suspension) hold up well with proper maintenance.
2. **Affordable Entry into ATV Ownership** Compared to modern ATVs, these older models are significantly cheaper to purchase, making them a good option for beginners or those on a budget. Parts and labor costs are also lower than newer machines.
3. **Simple Mechanics** The 225cc single-cylinder engine is straightforward to work on, with basic tools required for repairs. This makes it easier for DIYers to maintain or modify.
4. **Off-Road Capability** The YFM225 was designed for rough terrain, with a sturdy frame, long-travel suspension, and a low center of gravity. It can handle trails, sand, and light rocks if properly maintained.
5. **Modding Potential** The engine can be upgraded with aftermarket parts (e.g., performance carburetors, exhaust systems, or even a swap to a larger displacement like a 300cc or 400cc). The lack of modern electronics also means fewer compatibility issues with mods.
6. **Parts Availability** While not as abundant as for newer ATVs, Yamaha 59V parts (especially for the 225cc engine) are still widely available through dealers, online marketplaces, and salvage yards. Common components like spark plugs, belts, and filters are easy to source.
7. **Lower Insurance and Registration Costs** Older ATVs typically have lower insurance premiums and registration fees compared to modern, high-value machines.
8. **Nostalgia and Community** There is a dedicated community of Yamaha 59V owners who share knowledge, build kits, and restoration tips. This can be helpful for troubleshooting and finding support.

#### **Cons**
1. **Missing Critical Components (Mag Coil/Stator)** The fact that the mag coil and stator are missing is a **major red flag**. These parts are essential for generating electricity to charge the battery and run the ignition system. Without them, the ATV will not start, and the battery will drain quickly. Replacing them will require sourcing used or aftermarket parts, which may be expensive or difficult to find.
2. **No-Spark Condition** If the ATV is truly "no-spark," it means the ignition system is completely dead, likely due to failed coils, wiring, or a faulty ignition module. This will require professional diagnosis or extensive troubleshooting before any work can begin.
3. **Age-Related Wear and Tear** At 35-40 years old, the ATV may have hidden issues such as:- **Worn or leaking seals** (oil leaks from the engine or transmission).
- **Degenerated suspension** (shocks, bushings, or springs may be shot).
- **Rusted or broken frame components** (especially if stored outdoors).
- **Failed clutch or transmission** (slipping gears or difficulty shifting).
- **Exhaust system corrosion** (common in older ATVs).
4. **Fuel System Issues** Carburetors (likely a Mikuni or Yamaha-branded unit) can clog, leak, or lose adjustment over time. The fuel pump may also fail, requiring replacement.
5. **Electrical Problems** Older ATVs often suffer from corroded or broken wiring, dead batteries, or failing switches. The lack of a mag coil/stator means the electrical system is non-functional until repaired.
6. **Safety Concerns** Modern ATVs have improved safety features (e.g., better brakes, roll cages, and stability control). Older models lack these, increasing the risk of accidents, especially for inexperienced riders.
7. **Environmental and Emissions Regulations** In some areas, older ATVs may not meet current emissions standards, leading to restrictions on where they can be ridden or requiring modifications to pass inspections.
8. **Limited Aftermarket Support** While parts exist, modern aftermarket components (e.g., GPS, Bluetooth, or advanced suspension systems) are not compatible. Customization options are more limited compared to newer ATVs.
9. **Resale Value** Even in good condition, a 35-year-old ATV will have little to no resale value. If you plan to sell it later, the return on investment will be minimal.
10. **Time and Effort Required** Restoring an ATV of this age to full functionality will take significant time, mechanical skill, and patience. If you re not prepared for a long-term project, it may not be the best purchase.

### **Conclusion**
Buying a **1986-1991 Yamaha 59V-95510-20 ATV (YFM225) in no-spark condition with missing mag coil and stator** is a **high-risk, high-reward** proposition. The biggest hurdle is the **missing electrical components**, which will require immediate attention to even get the ATV running. If you re mechanically inclined, have access to parts, and are willing to invest time in restoration, this could be a fun project with the potential for a reliable off-road machine.
However, if you re looking for a **ready-to-ride ATV**, this purchase will likely require **thousands of dollars in repairs** before it s road-legal and functional. The lack of modern safety features, parts availability issues, and the age of the machine also make it a less practical choice for serious riders.
### **Recommendation**
- **If you re a DIY enthusiast with mechanical skills and access to parts:**- **Proceed with caution.** Prioritize sourcing a **working mag coil/stator** (check eBay, Facebook Marketplace, or ATV junkyards). Budget for a **full electrical system rebuild**, including wiring, battery, and ignition components.
- **Inspect the engine, transmission, and suspension** thoroughly before committing. Consider having a mechanic check for hidden damage.
- **Test the carburetor and fuel system** to ensure they re not clogged or leaking.
- **Plan for a long-term project** this ATV will not be "fixed" overnight.
- **If you want a reliable, ready-to-ride ATV:**- **Look for a newer model (2000s or later) in good condition** with a known service history. Brands like Honda, Kawasaki, or Polaris offer more modern, safer, and easier-to-maintain options.
- **Consider a used ATV with a working engine and electrical system** even if it s older, it will save you the hassle of rebuilding from scratch.
- **If you must buy an older ATV, aim for one with a known good engine and electrical system** (e.g., a 59V with a working mag coil or a later-model Yamaha with fewer issues).
- **If you re on a tight budget but want to ride:**- **Start with a cheaper, simpler project** (e.g., a lawnmower, snowmobile, or a non-electrical utility vehicle) to build mechanical skills before tackling an ATV restoration.
- **Join ATV restoration forums** (e.g., ATV.com, Yamaha 59V Facebook groups) to learn from others who ve successfully rebuilt similar machines.
**Final Verdict:** This ATV *could* be a great project if you re prepared for the work, but it s not a practical purchase for someone seeking a hassle-free riding experience. Weigh the cost of repairs against the value of your time and effort before buying.
