Need Some Wiring Help on a Go Kart..

I guarantee that switch doesn't have much current through it. Certainly not the full motor current. It probably turns on a relay, in which case just use the same type of switch and it will work fine. You might even want to replace it with a cool light-up switch so you have visual confirmation when it's on. Those switches just have 1 extra wire that goes to pos/neg depending on the switch.

It's like the small remote-turn-on wire for amps in car stereo systems...even though you have up to 28-volts (capacitors) 120-amps, and thousands of watts, the little wire and switch that turn the amps on when the head-unit is turned on don't carry anywhere near those loads, they only carry roughly <12v @ <5a...

...which, I'm pretty sure, is the same for the switch you (OP) are talking about as well.
