I wanna buy Polini 160cc cylinder kit for my Aprilia sx 125, 2t 2009 (rotax 122).

Do I need to buy some other parts in order to make things work with this kit, like carburetor or power valve? Stock is probably not good right?
Does someone have any experience using this kit?

The only upgrade I curretly have is Gianelli exhaust system.

Thanks for your answers :)
