BTK Supersport Go Kart Restoration

Before Restoration:

This ThunderKart was in rough shape. The  seat was falling apart, the greyhound 6.5 hp engine didn’t run, the maxtorque 20 series torque converter was sticking, and it just didn’t look so hot.

After Restoration

I kept the original seat  cover that said “thunderkarts” and redid the rest with high density foam, marine vinyl, and red welting (piping).


I also inserted some cabinet runner (found at any hardware store that sells carpet/cabinets) onto the floor pan to cover up the old nasty floor.


The seat looks pretty good. I fixed up the engine and,painted the rims, and those 22 inch knobby tires are my favorite part of the go kart.

I let my nephew test it out prior to selling this kart.

      1. Hey man. I think I bought this kart from you several Christmas’s ago. I came up late Christmas Eve and hauled it back. We still have it and enjoy it. I changed the front wheels out with some old Honda oddest wheels and new tires. Painted them to match the rear. It’s been real solid and starts on the first pull when we don’t let it sit six Months. Well just saw it on here and thought it was the same one and I’m sure it is.

        1. Do you still have this kart? I recently purchased one but it’s missing some pieces. I was wondering if you had a pic of the drive caddy. I don’t have the engine. I only have the pulley on the jack shaft. I’m just wondering what I need

          1. you can call gopowersports and see if they will help. This originally had an industrial 4 stroke engine. So a predator 212cc would work for the engine. For the drive unit, it originally had a 20 series torque converter (symmetrical). Look up a 20 series belt chart and see what size belt you can put on it given the distance between the drive unit and the driven unit shaft.
