Once again people saying things in this thread that they know nothing about. These engines start their life as 5hp briggs and end up as 1000 dollar race motors putting out 15+ HP easily capable of propelling your fat ass at 65mph. Without knowing exactly what specs this motor was built to it’s hard to say but geared right it should be able to do it. The kart itself looks pretty old and the LF tire certainly isn’t stock but it is worth a couple hundred for someone looking to get their kid into the novice class, or for a cheap beater.
