Why I Chose to Install a Big Bore Kit on My Warrior 350

As an avid off-roader and owner of a Yamaha Warrior 350, I was always looking for ways to improve the performance of my ATV. After doing some research, I came across the option of installing a big bore kit on my machine. At first, I was hesitant as it seemed like a costly and complicated upgrade. However, after weighing the pros and cons, I decided to go ahead with it. And let me tell you, it was one of the best decisions I have made for my Warrior 350.

The primary reason for installing a big bore kit is the significant increase in power and torque it provides. By increasing the displacement of the engine, more fuel can be burned in each cycle, resulting in a noticeable boost in performance. This is especially beneficial for trail riding or racing situations where you need that extra power to tackle obstacles or outrun your competitors.

Apart from increased power, another advantage of installing a big bore kit is improved reliability. The stock engine components are designed to work at their maximum capacity without much room for error. By increasing the displacement, you are reducing stress on individual parts, resulting in better longevity and reduced chances of breakdowns

My Buying Guide on ‘Warrior 350 Big Bore Kit’

As an avid ATV rider and owner of a Yamaha Warrior 350, I understand the need for upgrading and improving the performance of my vehicle. One of the best ways to do so is by installing a big bore kit on my Warrior 350. Here is my buying guide for anyone looking to purchase a Big Bore Kit for their Warrior 350.

What is a Big Bore Kit?

A big bore kit is an aftermarket upgrade for your ATV’s engine that increases its displacement, resulting in more power and torque. In simple terms, it makes your ATV bigger, faster, and more powerful.

Why do I need a Big Bore Kit for my Warrior 350?

The stock engine on the Yamaha Warrior 350 has a displacement of 348cc. By installing a big bore kit, you can increase the displacement by up to 30%, which means you can gain up to an additional 100cc in your engine. This results in a significant increase in horsepower and torque, making your ATV faster and more powerful.

Things to Consider Before Buying a Big Bore Kit

Before purchasing a big bore kit for your Warrior 350, there are several factors that you should consider:

1. Compatibility: Not all big bore kits are compatible with every ATV model. Make sure to check if the kit you are interested in is specifically designed for the Yamaha Warrior 350.

2. Brand: It is essential to research and choose a reputable brand when buying any aftermarket parts for your ATV. Look for reviews from other customers or seek recommendations from fellow ATV enthusiasts.

3. Budget: Big bore kits can range from $200-$600 depending on the brand and features included. Set a budget beforehand so that you can choose the best option that fits your budget.

4. Installation: Installing a big bore kit requires some mechanical knowledge and expertise. If you are not confident in doing it yourself, make sure to factor in the cost of professional installation when setting your budget.

5. Warranty: Always check if the big bore kit comes with a warranty or guarantee before making a purchase. This ensures that you have protection against any manufacturing defects or failures.

Benefits of Installing a Big Bore Kit on Your Warrior 350

1. Increased Power: As mentioned earlier, installing a big bore kit will significantly increase horsepower and torque of your ATV’s engine, giving it more power to conquer tough terrains.

2. Improved Acceleration: With increased power comes better acceleration. You will notice quicker throttle response and smoother acceleration with a big bore kit installed on your Warrior 350.

3. Better Performance at High Altitudes: If you love riding at high altitudes, then installing a big bore kit will give you an edge as it compensates for oxygen-depleted air at higher elevations.

4. Enhanced Durability: The larger piston size provided by the big bore kit reduces stress on individual parts of your engine resulting in improved durability and longevity of your ATV’s engine.

5.Better Fuel Efficiency: With increased performance comes better fuel efficiency as well! A properly tuned engine with bigger displacement allows fuel to burn more efficiently resulting in saving gas while riding.

Conclusion

Investing in a good quality big bore kit is one of the best upgrades you can make to improve the overall performance of your Yamaha Warrior 350 ATV. With proper research and consideration of all factors mentioned above, you can find the perfect big bore kit that suits both your needs and budget.
