Why My PW50 60cc Big Bore Kit Is Necessary
When I first started riding my PW50, I quickly realized that the stock engine was a bit underpowered for my growing skills and the types of trails I wanted to tackle. Installing a 60cc big bore kit made a huge difference. It gave my bike more power and torque, which meant I could accelerate faster and handle steeper hills without struggling. This upgrade truly transformed my riding experience, making it more exciting and enjoyable.
Another reason I found the big bore kit necessary is durability. The extra displacement reduces the strain on the engine when riding aggressively. Instead of pushing the stock 50cc engine to its limits, the 60cc kit provides a smoother, more reliable performance. This means fewer breakdowns and less maintenance, which is a huge plus for me since I like to spend more time riding than fixing.
Finally, as I improved my riding skills, I needed a bike that could keep up. The 60cc big bore kit gave me that extra edge, allowing me to progress faster and build confidence. It’s like giving my PW50 a new lease on life—more power, better performance, and a much more fun ride overall. For anyone serious about getting the
My Buying Guides on Pw50 60Cc Big Bore Kit
When I decided to upgrade my Yamaha PW50, the 60cc big bore kit was the perfect choice to get a bit more power and performance out of my little bike. If you’re thinking about doing the same, here’s my personal guide to help you pick the right kit and understand what to look for.
Why Upgrade to a 60Cc Big Bore Kit?
The PW50 comes with a 50cc engine, which is great for beginners and younger riders, but sometimes I wanted a little more speed and torque. The 60cc big bore kit increases the engine displacement, giving you better acceleration and overall performance without drastically changing the bike’s characteristics. It’s a popular and cost-effective way to enhance your ride.
What’s Included in a Typical Big Bore Kit?
When I bought my kit, it usually included a larger piston, cylinder, and sometimes a matching gasket set. Some kits also come with upgraded carburetor jets or a new exhaust gasket to help optimize performance. Make sure you check exactly what’s in the package so you don’t miss any necessary parts for installation.
Compatibility and Fitment
Not all big bore kits are made equal. I always double-checked that the kit was specifically designed for the PW50 model year I owned. Some kits are universal for the PW50 but might require minor modifications. Reading s or manufacturer notes helped me avoid fitment issues.
Material Quality and Brand Reputation
Since the big bore kit affects the engine’s core components, I looked for kits made from high-quality materials like forged aluminum or durable alloys. Brands with good reputations and positive user feedback gave me confidence that the kit would last and perform well. Avoiding cheap, no-name kits saved me from headaches down the road.
Installation Considerations
I’m not a professional mechanic, but installing the big bore kit was manageable with some patience and the right tools. However, if you’re unsure, it’s a good idea to get help from someone experienced or a shop. Some kits come with detailed instructions, which was a huge help for me.
Additional Modifications to Consider
After upgrading the engine size, I found that tuning the carburetor and possibly upgrading the exhaust system made a big difference. A bigger jet or a performance exhaust can help the engine breathe better and run smoothly with the increased displacement.
Price vs. Performance
Big bore kits come at various price points. I balanced my budget with performance goals, opting for a mid-range kit that had good reviews and reliable parts. Remember, sometimes spending a bit more upfront can save you money on repairs or upgrades later.
Final Thoughts
Upgrading my PW50 with a 60cc big bore kit was one of the best mods I’ve done to enhance my riding experience. By considering compatibility, quality, and installation ease, I found a kit that gave me more power without compromising reliability. If you’re ready for a bit more thrill on your PW50, a 60cc big bore kit is definitely worth exploring!
