Honestly, with the right tools, its pretty simple. the cylinder is held by 4 bolts and its just remove and swap (unless the piston diameter gets bigger, in that case you have to buy and swap the piston). After the whole cylinder swap, you have to regulate the gas-air ratio, and most likely you'll have to buy new jets and try them. after that you'll probably want to change the rollers from your variator and the contrast spring (this gives you more acceleration and slightly better top speed, if done correctly). I have the same scooter as this guy in the video with a slightly more serious mods.
and im thinking to put on gianneli extra v2, but my friends are saying that i will need to change the main jet, but maybe i can try lifting the needle? whats your opinion on this
