The Yamaha Blaster, a legendary ATV known for its raw power and aggressive handling, has captivated riders for decades. But for those seeking even more exhilarating performance, a big bore kit offers a significant upgrade. This comprehensive guide dives into everything you need to know about Yamaha Blaster big bore kits, addressing common questions and helping you make an informed decision.
What is a Yamaha Blaster Big Bore Kit?
A Yamaha Blaster big bore kit fundamentally increases the engine's displacement, leading to a substantial boost in power and torque. This is achieved by replacing the standard cylinder and piston with larger-capacity components. The increase in displacement directly translates to more cubic centimeters (cc), resulting in a noticeable improvement in performance. Kits typically range from modest increases to significant jumps in cc, allowing riders to tailor the upgrade to their desired level of performance.
What are the benefits of installing a Yamaha Blaster Big Bore Kit?
Installing a Yamaha Blaster big bore kit offers several compelling advantages:
- Increased Horsepower and Torque: This is the primary benefit. A larger displacement engine generates more power across the RPM range, making the Blaster significantly faster and more responsive.
- Improved Acceleration: The increased power translates directly to quicker acceleration, leaving stock Blasters in the dust.
- Enhanced Hill Climbing Ability: The added torque makes conquering challenging hills and terrains much easier.
- Greater Pulling Power: For tasks requiring towing or hauling, a big bore kit provides superior pulling power.
However, it's crucial to acknowledge potential drawbacks:
- Increased Wear and Tear: The larger engine components operate under increased stress, potentially leading to faster wear and tear if not properly maintained.
- Higher Fuel Consumption: The larger engine will naturally consume more fuel than the stock engine.
- Potential for Increased Maintenance: Regular maintenance is crucial to keep the engine running smoothly and prevent premature wear.
What size big bore kit is best for a Yamaha Blaster?
The optimal size of a Yamaha Blaster big bore kit depends heavily on your riding style and experience level. Beginners might find a moderate increase (e.g., +50cc) sufficient, while experienced riders might opt for more significant increases (e.g., +100cc or more). Larger kits generally offer more power but also demand more meticulous maintenance and may require additional modifications to the engine and transmission.
What other modifications are needed with a Yamaha Blaster Big Bore Kit?
To maximize performance and reliability after installing a big bore kit, consider these supplementary modifications:
- High-Performance Exhaust System: A free-flowing exhaust is crucial to evacuate the increased exhaust gases efficiently.
- Air Intake Modification: A larger air filter or a performance air intake system is needed to deliver the extra air required for the larger engine.
- Jetting Adjustment: Carburetor jetting must be adjusted to provide the correct fuel-air mixture for the larger engine. Incorrect jetting can lead to engine damage.
- Strengthened Clutch: A stronger clutch might be necessary to handle the increased power and torque.
- Gear Ratio Changes: Modifying the gear ratios might be beneficial depending on the chosen big bore kit size and riding style.
How much does a Yamaha Blaster Big Bore Kit cost?
The price of a Yamaha Blaster big bore kit varies based on the brand, displacement increase, and included components. Kits can range from a few hundred dollars to over a thousand dollars. It's essential to research different brands and compare features before making a purchase. Always factor in the cost of installation and any additional modifications needed.
Is installing a big bore kit difficult?
Installing a big bore kit is a relatively complex process, requiring mechanical aptitude and specialized tools. While some individuals might attempt a DIY installation, it's highly recommended to entrust the installation to a qualified and experienced mechanic to ensure proper assembly and avoid potential engine damage.
What are the common problems with Yamaha Blaster Big Bore Kits?
Common problems associated with big bore kits often stem from improper installation, insufficient maintenance, or neglecting supplementary modifications. Issues like incorrect jetting, insufficient cooling, and premature wear can occur if these aspects aren't addressed properly.
This comprehensive guide provides a solid foundation for understanding Yamaha Blaster big bore kits. Remember, always prioritize safety and seek professional help when needed. Enjoy the enhanced power and thrilling performance a big bore kit provides!
