Review SKI DOO 800x Power Exhaust Valves fits SUMMIT REV 800 2007

The **Ski-Doo Summit 800X (2007 model) 854880 Power Exhaust Valves (part numbers 2246-2, 2244, and 2245)** is a precision-engineered set of performance-critical components designed to enhance the efficiency, power output, and longevity of your Ski-Doo s exhaust system. These valves are integral to the **800X s high-performance engine**, which relies on optimal airflow for maximum throttle response, reduced backpressure, and improved fuel combustion. Crafted from high-grade, heat-resistant materials, these valves are engineered to withstand the extreme temperatures and pressures generated during high-speed operation, ensuring reliable performance even under the most demanding conditions. The **2246-2** is the primary intake valve, responsible for regulating the precise flow of air into the combustion chamber, while the **2244** and **2245** serve as the exhaust valves, expelling spent gases efficiently to maintain engine efficiency. Together, they form a critical trio that contributes to smoother acceleration, better fuel economy, and reduced engine wear over time. Whether you're tackling rugged trails, cruising through deep snow, or pushing the limits of your Ski-Doo s capabilities, these valves are built to deliver consistent, high-performance results. Replacing worn or damaged valves with these OEM-quality parts ensures that your Summit 800X operates at peak efficiency, extending the life of your engine and preserving its power potential for years to come.

### **Pros and Cons of Buying a 2007 Ski-Doo Summit 800X (Model 854880, Power Exhaust Valves 2246-2, 2244, 2245)**

#### **Pros**

1. **Performance and Power**

The 2007 Ski-Doo Summit 800X is equipped with a **800cc E-TEC engine**, which delivers strong performance for its time, making it suitable for both on-road and light off-road use. The **Power Exhaust Valves (2246-2, 2244, 2245)** improve exhaust flow, enhancing throttle response and power output compared to standard models.

2. **Reliability (for its era)**

Ski-Doo s E-TEC engines were known for being durable, especially when properly maintained. The 800X was a mid-range model, meaning it was less prone to the extreme wear issues sometimes found in high-performance or older models.

3. **Comfortable Ride**

The Summit 800X features a **comfortable seating position**, ergonomic controls, and a **suspension system** that absorbs bumps well for its class. The **windshield and fairings** provide good protection from wind and debris, making it suitable for highway riding.

4. **Aftermarket Support**

Being a popular model, parts like **exhaust valves, carburetors, and suspension components** are widely available. The **Power Exhaust Valves (2246-2, 2244, 2245)** are a known upgrade, meaning you can find replacements or modifications if needed.

5. **Fuel Efficiency (for its size)**

Compared to larger ATVs, the 800X has decent fuel efficiency, typically averaging **30-40 mpg** on mixed terrain, which is reasonable for a mid-sized ATV.

6. **Resale Value (if well-maintained)**

If the ATV has been **properly serviced and documented**, it may hold its value better than neglected units. The Summit line was well-regarded, so a clean example could still attract buyers.

7. **Versatility**

The Summit 800X is designed for **utility work, light off-roading, and farm use**, making it a practical choice for those needing an ATV for multiple tasks.

#### **Cons**

1. **Age and Wear**

The **2007 model age** means it may have **high mileage** (if not well-maintained), leading to **worn suspension, brakes, and drivetrain components**. Older ATVs are more prone to **engine wear, fuel system issues, and electrical failures**.

2. **Fuel Injection Reliability**

While E-TEC engines are robust, **fuel injectors and sensors** can fail over time, leading to **poor performance, rough idling, or stalling**. Replacing them can be costly.

3. **Suspension Degradation**

The **shock absorbers and springs** may be **softened or damaged** from years of use, reducing ride comfort and handling. Replacing them is an expensive upgrade.

4. **Braking System Limitations**

The **disc brakes** on older Ski-Doos can wear out, especially if the ATV was used aggressively. **Brake pads and rotors** may need frequent replacement, and the system may not stop as effectively as modern ATVs.

5. **Electrical Issues**

Older ATVs often suffer from **battery drain, faulty wiring, or failing alternators**, leading to **starting problems or electrical malfunctions**. The **ignition system** (if not upgraded) can also be unreliable.

6. **Exhaust and Emissions Compliance**

The **Power Exhaust Valves (2246-2, 2244, 2245)** modify emissions slightly, which may cause **check engine lights** or **inspection failures** in some regions. Some areas have strict emissions laws, so modifications may not be legal.

7. **Maintenance Costs**

Keeping an older ATV running requires **regular oil changes, air filter replacements, and spark plug checks**. If maintenance has been neglected, **major repairs (engine rebuild, transmission work)** could be expensive.

8. **Safety Concerns**

Older ATVs lack **modern safety features** like **traction control, electronic stability control, or advanced braking systems**. The **seat and roll bars** may not meet current safety standards.

9. **Fuel and Parts Availability**

While parts exist, **some components (especially rare or discontinued ones)** may be harder to find than in newer models. **Fuel quality** (if using older gas) can also degrade over time, leading to **carburetor or fuel system clogs**.

10. **Depreciation**

Like any used vehicle, the **resale value will be low** compared to newer ATVs. If you plan to sell it later, you may not recover much of your investment.

### **Conclusion**

The **2007 Ski-Doo Summit 800X with Power Exhaust Valves** is a **solid mid-range ATV** that offers **good performance, comfort, and utility** for its time. However, its **age introduces significant risks**, particularly if it has not been **well-maintained**. The **Power Exhaust Valves** are a nice upgrade for power, but they may not be worth the hassle if the rest of the ATV is worn out.

- **Thoroughly inspected** (engine, suspension, brakes, electrical system).

- **Fully serviced** (oil changes, air filter, spark plugs, fuel system).

- **Used for light to moderate duty** (not for extreme off-roading or heavy loads).

- **Budgeted for potential repairs** (especially if it has high mileage).

- A **newer Ski-Doo (2010 ) with a modern E-TEC or E-TEC X engine** (better reliability, safety, and parts availability).

- A **well-documented used ATV with recent service records** (proves it has been cared for).

- A **different brand** (Honda, Can-Am, or Yamaha) if you prefer a different engine type.

### **Final Recommendation**

You **find a well-maintained example** (with service records).

You **inspect it thoroughly** (engine, suspension, brakes, electrical system).

You **budget for potential repairs** (especially if it has high mileage).

You **plan to use it lightly** (not for extreme conditions).

You **cannot afford major repairs** (engine, transmission, suspension).

You **find it without maintenance history** (risk of hidden issues).

You **need a modern ATV with safety features** (better braking, traction control).

If you want a **reliable, low-risk ATV**, consider a **used 2012 Ski-Doo Summit or Renegade with a modern engine**. If you prefer **better off-road capability**, a **Can-Am Maverick or Honda TRX250X** might be a safer long-term investment.
