The chain problem is the engine is mounted to the frame and the axle is is on the suspension so every time you hit a bump or make it squat by spinning out the chain loosens up. The engine used to be mounted to the axle so it pivoted with the axle and the chain tension did not change. Either hard mount the axle by taking the shocks off and bolting up a piece of steel in its place or weld it solid so it won't move. That's the problem guys.

YES YES YES WE WE NEEDED THIS

This is inspiring. Can't wait to make my shopping cart faster!

You should’ve gone Home and bought a predator 670

In the harbor freight that I live near has a 670 cc engine

As soon as that frozen bearing fit into that piece. I broke my phone smashing the subscribe button. 💥

you can sometimes find a v-twin 670 at harbor freight

What a project

Woooooooooooooo 😂😂😂 weee needed this so badddd

“We’re talking a hair off from hitting the shock but hey…fuck it” What a wild way to live you savages

Amazing

The 459 is not the biggest engine they have a 670 but still a cool go kart love the vids keep up the great work

600 predator V twin next 😂

So just weld up the bottom and add more support so it’s sturdy asf and like paint it nice then take it somewhere cool

Put on a smaller chain sprocket on that and it will increase the acceleration 🫡

try a chain tensioner

Cool video, I’ve been watching the shorts on this. Looks like the hub on the tire that broke isn’t the right one. I could be wrong but I deal with these Chinese karts a good bit. I have 3 of them lol

THIS IS WHAT WE’VE BEEN WAITING FOR THANK YOU !!!

Take the governor off and she’ll wheelie 😂😂

10/10❤😂

Alrìigggghhhttt.. been waiting for a video of this thing 🤙

A little more voiceover throughout the video would help tie the story together and make it so you don't have to constantly explain what you're doing every time you turn on the camera. look at Mark Rober for example, he keeps the audience interested by explaining what's going on through voiceover while he is showing the action on the screen. nice work though it looks fun

I used to know exactly but i think its like 1/1000th of an inch per 100⁰ of temperature change for steel
