I just purchased a 2012 Yamaha Zuma 50F to get around my college campus and I was wondering how I can improve performance by making its top speed and acceleration greater. Right now I can get it up to 40-42 MPH. What can I do, that is relatively inexpensive, that will increase the top speed of my little moped? Please feel free to share prior experiences with modifying your zuma and how significant the alteration was on top speed and acceleration.
