I Upgraded My Harbor Freight Go Kart to the MAX!
In this video, we take our 670cc-swapped mini rat rod to the absolute MAX! We build fully custom suspension, upgrade a few weak points you guys mentioned in the comments, and dial this thing in for maximum performance. Watch until the end to see it rip harder than ever!
