Why My PW50 Needs a 60cc Big Bore Kit
When I first started riding my PW50, I enjoyed the bike’s reliability and ease of use, but I quickly realized it lacked the power I wanted as I got more confident. Installing a 60cc big bore kit was a game-changer for me. The increase in engine displacement gave my bike a noticeable boost in horsepower and torque, making acceleration smoother and more responsive. This upgrade allowed me to tackle tougher trails and hills that felt impossible before.
Another reason the big bore kit was necessary for me is that it extended the bike’s usability. The PW50 is great for beginners, but as I improved, I needed more performance to keep challenging myself. The 60cc kit effectively turned my bike into a more capable machine without sacrificing its lightweight and nimble feel. Plus, it was a relatively simple and affordable modification that delivered impressive results, making it a worthwhile investment in my riding experience.
My Buying Guides on Pw50 60Cc Big Bore Kit
When I decided to upgrade my Yamaha PW50, I knew a 60cc big bore kit was the way to go for better power and performance. After some research and hands-on experience, I’m sharing what I learned to help you choose the right kit for your needs.
Why Upgrade to a 60Cc Big Bore Kit?
I wanted more speed and torque from my PW50 without completely changing the bike. The 60cc big bore kit increases the engine displacement from 50cc to 60cc, giving a noticeable boost in power. It’s a popular and affordable upgrade that keeps the bike reliable and fun.
What’s Included in a Typical Big Bore Kit?
Most kits come with a larger cylinder, piston, rings, wrist pin, and circlips. Some also include gaskets and a head gasket for easier installation. When I bought mine, I made sure the kit had everything I needed so I wouldn’t have to order extra parts later.
Compatibility and Fitment
Not all kits fit every model year or variant of the PW50 perfectly. I double-checked my bike’s year and model to ensure the kit I chose was compatible. Reading product descriptions carefully and checking user reviews helped me avoid any fitment issues.
Material Quality and Brand Reputation
I looked for kits made from durable materials like high-grade aluminum with a quality finish. Brands with good reputations and positive customer feedback gave me confidence that the kit would last and perform well. Avoiding cheap knockoffs saved me from headaches down the road.
Installation Considerations
Installing a big bore kit requires some mechanical skills and tools. I made sure I had a service manual handy and took my time during installation. Some people prefer professional installation to avoid mistakes. If you’re like me and enjoy working on your bike, it can be a rewarding project.
Additional Upgrades to Consider
After installing the kit, I also upgraded the carburetor and exhaust system to match the increased airflow and power. These upgrades help optimize performance and prevent engine issues. It’s worth budgeting for these if you want the best results.
Price vs. Performance
Big bore kits come in a range of prices. I balanced cost with quality by choosing a mid-range kit that had good reviews and reliable performance. Cheaper kits might save money upfront but can lead to costly repairs later.
My Final Tips
- Always verify compatibility with your exact PW50 model.
- Invest in a quality kit from a trusted brand.
- Don’t rush installation; follow instructions carefully.
- Consider supporting mods like carb and exhaust upgrades.
- Read reviews and ask the community for advice.
