My Buying Guide on ‘Big Bore Kit For 50Cc Scooter’

Hello everyone! As a proud owner of a 50cc scooter, I have always wanted to upgrade its performance and speed. After doing some research, I found out about the big bore kit for 50cc scooters. This kit is designed to increase the engine’s displacement, resulting in more power and higher top speed. In this guide, I will share my experience and provide some tips for buying the right big bore kit for your 50cc scooter.

What is a Big Bore Kit?

A big bore kit is an aftermarket upgrade that increases the engine’s displacement by replacing the cylinder and piston with larger ones. In simple terms, it makes your engine bigger and more powerful. The stock 50cc engine usually has a displacement of around 49cc, but with a big bore kit, you can increase it up to 80cc or even more.

Why Should You Consider A Big Bore Kit?

If you are looking for more power and speed from your 50cc scooter, then a big bore kit is definitely worth considering. It will not only give you a boost in performance but also improve your scooter’s acceleration and overall riding experience. Moreover, it is also a cost-effective solution compared to buying a new scooter with a bigger engine.

Factors to Consider Before Buying A Big Bore Kit

Bike Compatibility: The first thing you need to consider is whether the big bore kit is compatible with your scooter or not. Different scooters may require different kits, so make sure to check the compatibility before making any purchase.

Brand: There are various brands that offer big bore kits for 50cc scooters. It is essential to choose a reputable brand known for its quality products and good customer reviews.

Budget: Big bore kits come in different price ranges depending on the brand and features. Set a budget and choose a kit that fits within it without compromising on quality.

Cylinder Material: The cylinder material plays an important role in determining the durability and performance of the big bore kit. Most kits use aluminum or cast iron cylinders, but aluminum cylinders are known to provide better heat dissipation.

Piston Size: The piston size determines how much displacement will be added to your engine. You can choose from various sizes depending on how much power you want to add to your scooter.

Tips for Installing A Big Bore Kit

  • Make sure to read the installation instructions carefully before starting the process.
  • If you are not confident about installing it yourself, seek professional help.
  • Clean all parts thoroughly before installation to avoid any debris getting into the new components.
  • Tune up your carburetor after installation as it may need adjustments due to increased airflow from the bigger cylinder.
  • Take your time during installation and double-check everything before starting your scooter for the first time after installation.

In Conclusion

A big bore kit can be an excellent upgrade for your 50cc scooter if chosen wisely and installed correctly. It will give you better performance without breaking the bank. However, make sure to do proper research and consider all factors before making any purchase decision. I hope this guide was helpful in providing insights into buying a big bore kit for your beloved 50cc scooter!
