The Yamaha Blaster, a legendary two-stroke ATV, holds a special place in the hearts of many off-road enthusiasts. Its compact size, lightweight design, and raw power make it a favorite for riders of all skill levels. But for those seeking even more performance, a big bore kit is the ultimate upgrade. This comprehensive guide dives deep into everything you need to know about Yamaha Blaster big bore kits, helping you choose the right one and understand the implications of this significant modification.
What is a Yamaha Blaster Big Bore Kit?
A Yamaha Blaster big bore kit increases the engine's displacement, allowing for a significant boost in power and torque. This is achieved by replacing the standard cylinder and piston with larger components. The increase in displacement translates to a larger combustion chamber, leading to a more potent explosion and, consequently, increased horsepower and torque output. Kits typically come with all the necessary components for installation, including the cylinder, piston, rings, gaskets, and sometimes even a modified carburetor jetting.
What are the Benefits of a Big Bore Kit for my Yamaha Blaster?
Upgrading your Blaster with a big bore kit offers several compelling advantages:
- Increased Horsepower and Torque: This is the primary reason riders opt for a big bore kit. You'll experience a noticeable increase in power, making hill climbs easier and acceleration more exhilarating.
- Improved Performance: The added power translates to improved overall performance, enhancing your riding experience whether you're tackling trails or cruising across open fields.
- Enhanced Top Speed: Depending on the kit and other modifications, you can expect a boost in top speed.
- Greater Pulling Power: Big bore kits provide substantially more torque, making it easier to pull through challenging terrain.
What are the Different Sizes of Yamaha Blaster Big Bore Kits Available?
Big bore kits for the Yamaha Blaster are available in various sizes, commonly ranging from 200cc to 270cc. The larger the displacement, the greater the power increase. However, it's important to consider the implications of significantly increasing the displacement. Larger kits often require additional modifications, such as strengthening the connecting rod or crankshaft, to handle the increased stress.
What are the Drawbacks of a Yamaha Blaster Big Bore Kit?
While big bore kits offer significant performance gains, it's crucial to be aware of potential drawbacks:
- Increased Wear and Tear: The higher power output puts more stress on engine components, potentially leading to increased wear and tear if not properly maintained. Regular maintenance is crucial.
- Higher Fuel Consumption: Expect an increase in fuel consumption with a larger displacement engine.
- Increased Engine Noise: The larger engine may produce more noise.
- Potential for Engine Damage: Improper installation or lack of proper maintenance can lead to engine damage.
How Much Does a Yamaha Blaster Big Bore Kit Cost?
The cost of a Yamaha Blaster big bore kit varies depending on the brand, size, and included components. Expect to pay anywhere from a few hundred to over a thousand dollars. Remember to factor in the cost of installation, if you're not performing it yourself, and any additional parts you might need.
What else do I need to upgrade besides the big bore kit?
A big bore kit is often only the beginning. Other modifications may be necessary or highly recommended to fully realize the potential of the upgraded engine and to ensure its longevity. These may include:
- Modified Carburetor Jetting: A larger carburetor or adjusted jetting is often necessary to provide the increased fuel flow required by the larger engine.
- Strengthened Crankshaft and Connecting Rod: For larger big bore kits, these components may need upgrading to handle the increased stress.
- High-Performance Exhaust System: A performance exhaust system can significantly improve the engine's breathing and further enhance power.
How difficult is it to install a Yamaha Blaster Big Bore Kit?
Installing a big bore kit requires mechanical aptitude and the right tools. While some individuals successfully perform the installation themselves, it's recommended to have the work done by a qualified mechanic, especially for larger kits. Incorrect installation can result in engine damage.
What are some of the top brands for Yamaha Blaster Big Bore Kits?
Several reputable brands produce Yamaha Blaster big bore kits. Research and compare different options to find one that fits your budget and performance goals. Reading reviews from other users is highly beneficial in making an informed decision.
This guide provides a comprehensive overview of Yamaha Blaster big bore kits. Remember to always prioritize safety and proper maintenance to fully enjoy the enhanced performance these kits provide.
