If your dealer is on top of things he would have done a basic derestriction on the bike for you. Have you asked them? Basic derestriction would be an 85 or 88 jet & a derestricted drive clutch boss/sleeve. From there you can make it as complicated & expensive as you want. CDI, intake, air filter, exhaust, variator...... Remember it's only 50cc's. The more RPM's you turn (revolutions per minutes X every minute you drive) the shorter the engine life & more gas you'll use
