Review SUZUKI Cam Contact Braker On Rotor fits T250 250 1972

The **Suzuki 1972 T250 250cc Cam Contact Breaker Rotor (Part #31724-15021)** is a meticulously engineered component designed specifically for Suzuki s iconic T250 dirt bike, a model celebrated for its reliability, simplicity, and off-road prowess during the early 1970s. This contact breaker rotor, a critical part of the bike s classic points ignition system, plays an essential role in generating the electrical impulses necessary to fire the spark plugs, ensuring smooth and consistent engine operation. Crafted from durable metal, this rotor features a precision-machined cam lobe that interacts with the contact breaker points to interrupt and restore the electrical current at precisely timed intervals, allowing the ignition coil to produce the high-voltage spark required for combustion. The design reflects the mechanical ingenuity of the era, where simplicity and robustness were prioritized over modern electronic sophistication, making it a sought-after part for restorers, collectors, and enthusiasts who appreciate the raw, unadulterated performance of vintage two-stroke engines. Whether used in a fully restored T250 or as part of a carefully maintained classic bike, this rotor exemplifies the timeless engineering that defined Suzuki s reputation for building bikes that could handle the toughest trails with ease. Its compatibility with the 250cc displacement ensures that it fits seamlessly into the bike s original ignition setup, providing the reliable spark needed to keep the engine running strong whether on a weekend ride through rugged terrain or during a meticulous rebuild to return the bike to its original glory. For those who value authenticity and mechanical integrity, this rotor is an indispensable piece, bridging the gap between vintage performance and modern restoration efforts.

### **Pros and Cons of buying a Suzuki 31724-15021 (1972 T250 250cc Cam Contact Breaker Rotor)**

#### **Pros:**

1. **Historical and Collectible Value** The 1972 Suzuki T250 is a classic dirt bike, highly sought after by enthusiasts for its vintage design, cultural significance, and rarity. If you plan to restore or preserve it, its value may appreciate over time.

2. **Proven Reliability** Suzuki s early dirt bikes were built to last, and the T250 s simple, robust engine (a single-cylinder, two-stroke) is known for durability with proper maintenance. Many original examples still run after decades.

3. **Modification Potential** The T250 has a strong aftermarket support system, with parts available for upgrades (e.g., modern carburetors, high-performance cams, or suspension kits). This makes it a good platform for customization.

4. **Lower Running Costs (Compared to Modern Bikes)** Two-stroke engines like the T250 s are simpler and cheaper to maintain than modern four-strokes. Oil changes are minimal (just two-stroke oil), and basic repairs (e.g., valve adjustments, piston replacements) are straightforward.

5. **Lightweight and Maneuverable** The T250 is small and nimble, making it ideal for tight trails or urban riding. Its low weight (around 180 200 lbs) makes it easier to handle than larger modern bikes.

6. **Nostalgia and Riding Experience** For those who appreciate the raw, unfiltered feel of a vintage bike, the T250 offers a different riding experience than modern bikes with electronic aids. The contact breaker ignition system (as opposed to modern electronic ignition) adds to its classic charm.

7. **Parts Availability** While some original parts may be hard to find, the T250 has been around long enough that most common components (e.g., carburetors, chains, brakes) are still produced or easily sourced from third-party manufacturers.

#### **Cons:**

1. **High Maintenance Requirements** The contact breaker ignition system is mechanically complex and prone to wear. It requires frequent adjustments (points gap, condenser checks) and can fail unpredictably, leading to stalling or no-start conditions. Modern electronic ignition systems are far more reliable.

2. **Poor Fuel Efficiency and Environmental Impact** Two-stroke engines mix oil with gasoline, which is inefficient and polluting. The T250 s fuel consumption is high, and it produces more emissions than modern bikes, making it less practical for daily use.

3. **Outdated Safety Features** The T250 lacks modern safety advancements such as disc brakes (it typically comes with drum brakes), advanced suspension systems, or traction control. Its braking and handling are less precise compared to contemporary bikes.

4. **Limited Comfort and Ergonomics** The bike s design is basic by today s standards. The seat is hard, the footpegs are low, and the handlebars are narrow, which can lead to discomfort during long rides. Modern bikes offer better ergonomics for extended use.

5. **Reliability Issues with Age** Even with proper care, a 50-year-old bike will eventually develop wear in critical components like the clutch, transmission, or frame. Rust, worn bearings, and degraded rubber parts (e.g., tires, seals) are common in older bikes.

6. **Insurance and Legal Restrictions** Vintage bikes may be harder to insure, especially if they re not registered for modern use. Some areas have restrictions on older bikes, particularly if they lack modern safety equipment (e.g., lights, mirrors).

7. **Resale Value Uncertainty** While some classic bikes appreciate in value, the T250 s market is niche. If you decide to sell later, the value may not recover your initial investment, especially if the bike has been heavily modified or neglected.

8. **Performance Limitations** The T250 s power output (around 18 20 hp) is modest by today s standards. It struggles against modern bikes in terms of acceleration, top speed, and climbing ability, making it less versatile for varied terrain.

9. **Contact Breaker System Reliability** The ignition system is notorious for misfiring, especially in wet conditions. It requires precise tuning and can fail suddenly, leaving you stranded. Replacing it with an electronic ignition (e.g., from a modern Suzuki or aftermarket kit) is possible but adds complexity.

10. **Tooling and Knowledge Required** Working on a T250 often requires specialized tools (e.g., old-school wrenches, feeler gauges for points adjustment) and mechanical skill. Many modern mechanics may not be familiar with two-stroke contact breaker systems.

### **Ending Conclusion:**

The Suzuki 31724-15021 (1972 T250 cam contact breaker rotor) is a fascinating piece of motorcycle history, offering a unique riding experience and potential for restoration or modification. It is best suited for enthusiasts who prioritize nostalgia, collectibility, or the challenge of maintaining a vintage machine. However, it is not a practical choice for daily riding, long-distance travel, or those seeking modern reliability and safety.

If you are mechanically inclined, enjoy tinkering, and have the patience to deal with its quirks, the T250 can be a rewarding project. For most riders today, however, the trade-offs in reliability, performance, and maintenance outweigh the benefits. A modern dirt bike (even a used one) would likely provide a better balance of fun, safety, and practicality.

---

### **Recommendation:** - **Buy it if:**

- You are a collector or restorer with a passion for vintage motorcycles.

- You have experience working on two-stroke engines and are prepared for frequent maintenance.

- You plan to use it primarily for leisurely riding, track days, or as a static display piece.

- You are willing to invest time and money in upgrading critical components (e.g., replacing the contact breaker ignition with electronic ignition, modernizing brakes, or upgrading the suspension).

- **Avoid buying it if:**

- You expect a reliable, low-maintenance bike for regular riding.

- You prioritize modern safety features, comfort, or performance.

- You lack mechanical skills or access to tools for proper upkeep.

- You are not prepared for the possibility of frequent breakdowns or high repair costs.

**Alternative Options:**

- If you love the T250 s aesthetic but want reliability, consider a **modern replica** (e.g., a custom-built bike using a modern engine in a vintage frame) or a **restored T250 with modern upgrades** (e.g., electronic ignition, disc brakes).

- For practical dirt biking, a **used modern two-stroke** (e.g., Honda CR125, Kawasaki KLX110) or a **budget-friendly four-stroke** (e.g., Yamaha WR250R, Honda CRF250L) would offer a better balance of fun and functionality.
