i thought bike chain was ANSI standard #40... which is also what a lot of carts use.
I've noticed that bike chains tend to be much more expensive than kart chains (#40).
So if anything this tells me that a bike chain could be stronger and/or lighter in weight.
Maybe I'm just looking at the high-end bike stuff...?

I was on this chain issue the other day, and i found some lengths (10 foot) of different ANSI standard chain from surpluscenter for cheap, and i believe that they claimed the chain to be for go-karts and/or mini-bikes.

I wanna say it was in the 30 dollar price range for 10 feet... which makes it way cheaper than other bike chains that are also ANSI 40. If you go bike chain I would suggest you get the chain made for single-speed bikes, I think its a little stronger. and i think the special chain for the freestyle bmx guys is even stronger.

Look at it this way, a human on a bicycle exerts roughly 1/2 horsepower. Bicycle chain can certainly handle this.
Now, put a 5, 6.5, 13, 18 HP motor on there. The #40 ONLY indicates the distance between the rollers, not if it is for karts, it is not a gauge of strength, it is a measurement. It comes in different widths to suit your needs. The number can be used to identify pitch in the following way: the first digits identify the pitch in 1/8" increments, and the last digit is 0 for standard proportions, 1 for lightweight chain, and 5 for rollerless bushed chain. A #41 sprocket is therefore for 1/2"-pitch lightweight chain, a #120 sprocket is for 1-1/2" pitch chain, etc.
