Description:

This Top End Kit is a complete gasket set designed specifically for the Yamaha PW50 minibike model years 1981 to 2018. It includes all the necessary gaskets for the cylinder piston head area, ensuring a perfect seal and optimal engine performance.

By replacing these gaskets, you can restore the sealing integrity of your Yamaha PW50 engine, improve its performance, and extend its lifespan. This Top End Kit is an essential upgrade for any PW50 minibike owner looking to maintain their vehicle in top condition or prepare it for competition use.

Please note that installation of this kit requires some mechanical knowledge and experience. It is recommended to consult your vehicle's repair manual or consult with a professional mechanic if you are unsure about the installation process.
