top speed
Remember that your top speed can change due to over all wheel diamater as well as gearing. You probably are going to have a hard time getting 50 mph with a drive gear of 12 tooth. Most people use these for arena racing where they are trying to keep there RPM's up where they are getting consistant power. If you want a higher top speed try a 15 tooth driver with the 60 maybe 58/59 tooth wheel gear. you will find that your kart wont take off as fast but the top speed will be achived. If your wheels are less than say, 11 inches tall you may still have problems. A word of caution, 50 MPH is moving! watch out for everything that can get in your way and wear a helmet.
