Modern Vespa

Good day to everyone am new to this page but I came across a old post about fitting a fuoco 500 cylinder onto gp 800 or srv 850 but in my case i own a srv 850 and would like to know if the fuoco 500 cylinder will work on my srv 850 and what tips and steps should I take to make sure the project becomes successful... Can anyone give me some advice and tips please I would love to turn my srv850 to a monster but just want to make sure i don't waste money in buying parts that will not work and get the best advice possible from someone who already done such great work... Thanks in advance and stay safe on the streets💯👊🏽

My mechanic in Vzla do this changes no less that 5-6 times, using the old 460cc cylinders, and yes the result is a beast on two wheels

Thanks for the reply do you know of the 500 cylinders from the fouco am about to purchase that 1 but just wanted confirmation that it would would fit my srv 850
