Instagram: rollexx_tv Today I'll show you how to convert your Piaggio scooter from 125ccm to 172ccm step by step! With this cylinder kit you get a significant increase in torque and horsepower! Don't forget to re-tune your carburetor and modify the air filter! Guideline for the jets: Main jet: approx. 90 - 98 Secondary jet: approx. 42 - 45 Tightening torque for the cylinder head nuts: 22-24 Nm (All information is without guarantee and varies from scooter to scooter) The cylinder is a lot of fun in combination with a larger carburetor! With a 25 carburetor, the acceleration, the pulling power and the top speed can be significantly increased! The principle can also be applied to other cylinder conversions! Enjoy watching!
