Whats the weight Limit?

Whats the weight limit on these things? This in Louisiana at the Kart Ranch when we get to visit our friends. It's pretty fun they have bumper boats, miniature golf and batting cages. It's like a tradition or something to go there when we go up there. Me and David get on one car and my friend John get on the pink car it's funny but it was the fastest car out there. Notice we are in the fatty cars not the singles like the ones on the top left of the picture. John would ask for the extension on the seat belt he said he had to much junk in the hood that is why the seat belt wouldn't fit. "Man we had a time", to quote Bro Randy Sutherland. Laters
