The Necessity of a PW50 Big Bore Kit – My Experience

I have been riding my PW50 for a few years now, and while it has been a great bike for learning, I recently felt like it was time for an upgrade. After doing some research, I found that one of the best ways to increase performance on a PW50 is by installing a big bore kit. At first, I was hesitant about making this modification, but after experiencing the difference it made, I can confidently say that a big bore kit is necessary for any serious rider.

The main reason why a PW50 big bore kit is necessary is because it significantly increases the bike’s power and torque. The stock engine on a PW50 has limited power and can feel sluggish at times. With the big bore kit, the engine displacement is increased, allowing for more fuel and air to be burned and creating more power. This translates into faster acceleration and better overall performance on the track or trail.

Another reason why a big bore kit is necessary is that it improves the bike’s reliability. The stock engine on a PW50 can be prone to overheating and causing damage if pushed too hard. With the bigger engine size of the big bore kit, there is more space

My Buying Guide on ‘Pw50 Big Bore Kit’

As a proud owner of a Yamaha Pw50 dirt bike, I have always been looking for ways to improve its performance. One upgrade that has made a noticeable difference is installing a big bore kit. This kit helps to increase the engine’s displacement, resulting in more power and torque. After researching and trying out different options, I have put together this buying guide to help fellow Pw50 owners make an informed decision when purchasing a big bore kit.

What is a Pw50 Big Bore Kit?

A Pw50 big bore kit is an aftermarket upgrade that includes a larger cylinder, piston, and gaskets. It is designed to increase the engine’s displacement from the stock 49cc to either 60cc or 72cc, depending on the kit chosen. This results in an increase in horsepower and torque, giving your bike more power and acceleration.

Why Should You Consider Upgrading to a Big Bore Kit?

If you are looking for an affordable way to increase your Pw50’s performance, then upgrading to a big bore kit is definitely worth considering. The larger displacement will result in improved acceleration and top speed, making your bike more fun to ride. It also provides better low-end torque, making it easier to ride on challenging terrains.

Things to Consider Before Buying

  1. Budget: Before making any purchase, it is essential to determine your budget for the upgrade. Big bore kits can range from $100-$300+ depending on the brand and size.
  2. Engine Size: As mentioned earlier, there are two sizes available for the Pw50 – 60cc and 72cc. Consider which size would be suitable for your riding needs before making a decision.
  3. Brand Reputation: It is essential to do some research on different brands offering big bore kits for the Pw50. Look for reviews from other users and check their reputation in the market.
  4. Durability: Since this is an investment for your bike’s performance, make sure to choose a durable option that will last you a long time without any issues.

Benefits of Choosing a Quality Big Bore Kit

  • Increase in Performance: A good quality big bore kit will provide significant improvements in power and torque compared to stock.
  • Better Fuel Efficiency: With increased power comes better fuel efficiency since your engine won’t have to work as hard as before.
  • Ease of Installation: Most big bore kits come with detailed instructions and can be easily installed with basic tools by following them carefully.
  • No Modifications Required: A quality big bore kit should not require any additional modifications or upgrades for it to work correctly on your bike.

Tips for Installing Your Big Bore Kit

  1. Cleanliness: Make sure your workspace is clean before starting the installation process. Any dirt or debris can cause damage when working on sensitive engine components like pistons and cylinders.
  2. Familiarize Yourself with Instructions: Read through the instructions provided carefully before starting the installation process. Familiarize yourself with each step beforehand so that you know what tools are required and what needs to be done.
  3. Piston Rings Placement: Pay attention while installing piston rings as they need to be placed correctly for optimal performance. Improper placement can result in decreased power or even engine damage.
