My Buying Guides on Warrior 350 Big Bore Kit
When I decided to upgrade my Yamaha Warrior 350, the Big Bore Kit was an obvious choice to boost performance and get more power out of my ride. If you’re considering the same, here’s everything I learned during my research and buying experience to help you make the right decision.
Why I Chose a Big Bore Kit for My Warrior 350
The stock 350cc engine is reliable but somewhat limited in power. I wanted more torque and horsepower for better acceleration and improved trail performance. A Big Bore Kit increases the engine displacement by replacing the cylinder and piston with larger components, which is a cost-effective way to gain extra muscle without swapping the entire engine.
What’s Included in a Typical Warrior 350 Big Bore Kit?
Most kits I found include:
- A larger cylinder (usually around 400cc)
- A matching high-performance piston
- Rings and gaskets
- Installation instructions
Some kits may also come with upgraded bearings or a head gasket, so I made sure to check the full contents before buying.
Compatibility and Fitment
I double-checked that the kit was designed specifically for the Yamaha Warrior 350 (years and model numbers vary). Some kits fit only certain years, so confirming compatibility with my bike’s VIN and model year saved me from headaches. Make sure to verify this with the seller or manufacturer before purchasing.
Performance Gains I Experienced
After installing the kit, I noticed:
- Increased low-end torque, making hill climbs easier
- Improved throttle response and acceleration
- A slight increase in top speed
Keep in mind, to get the best performance, you may need to adjust your carburetor or fuel management system to match the new engine size.
Installation Tips from My Experience
If you’re handy with tools, installing the kit yourself is doable, but it requires patience and some mechanical knowledge. Here’s what helped me:
- Follow the instructions carefully and don’t rush
- Replace any worn seals or gaskets during installation
- Use a torque wrench to tighten bolts to spec
- Clean the engine thoroughly before assembly to avoid contamination
If you’re unsure, I recommend seeking help from a professional mechanic.
Additional Upgrades to Consider
To complement the Big Bore Kit, I also upgraded:
- Exhaust system for better airflow
- Air filter to improve breathing
- Carburetor jetting to optimize fuel delivery
These modifications helped me unlock the full potential of the kit.
Where I Found the Best Deals
I compared prices from online retailers, ATV specialty shops, and forums. Sometimes, buying from a reputable dealer who offers a warranty is worth the extra cost over generic kits from unknown sellers. Also, look out for combo deals that include installation tools or extra parts.
Final Thoughts
The Warrior 350 Big Bore Kit was one of the best upgrades I made to my bike. It gave me the power boost I wanted without breaking the bank. Just be sure to research compatibility, quality, and installation requirements before buying. With the right kit and a little elbow grease, you can transform your Warrior 350 into a more powerful machine.
I hope my buying guide helps you make an informed choice and enjoy your upgraded ride as much as I do!
