420cc Go Kart Top Speed | Our New Fastest Build! | TYRANIS EP41

After removing the governor from Big Bob's 420cc Predator engine, we figured it was time to lock in his official top speed. This is specifically testing top speed for, Stage 1 and our offroad oriented 7:1 gear ratio. I plan on swapping to a 6:1 ratio and maybe even 5:1 in a future video to show the impact of gearing on top speed and low end performance. BUT THATS FOR LATER Comment your guess for Big Bob's top speed down below! www.tyraniscustoms.com
