You can't jet a bike or fit rollers and springs for speed. That's not how it works. Your cylinder makes the power and the setup parts are to make use of it. You should read the guides to start off with. http://www.scootershack.co.uk/carbguide.html http://www.scootershack.co.uk/rollerguide.html http://www.scootershack.co.uk/newbie-scooter-tuning/scooter-carburetor-jetting-guide-t2747.html etc.
