In terms of actual speed it's rather minimal. Maybe you'll see a 3-5 MPH at best. The REAL difference you'll see is consistency and better overall running qualities of the scooter, better starts and smoother overall engine performance are never a bad thing so don't be discouraged by doing the upgrades! Remember though, there is no replacement for displacement, so if it's top end you want, a BBK or engine swap is the ticket.
