Installing a big bore kit can be complicated and time-consuming so it’s important to make sure you have all the necessary tools and know-how before beginning the installation process. If you’re not confident in your ability to install a big bore kit, it’s best to seek professional help from an experienced mechanic or technician who can do the job for you.

Cost:
Another factor to consider when choosing a big bore kit for your 50cc scooter is cost.
