Default Sprocket, clutch, chain

Im new to all this and was looking for help. How many T centrifugal clutch should I use on a 54 T sprocket? Chain size? Im running 13 in wheels. I have two carts both with 54t sprockets. One has a predator 212 and the other is a Tecumseh 5hp power sport.

Thanks in advance for help.

Welcome to the forum! 10T clutch for #41/420 chain would be your best bet over a 12T #35 chain clutch. A 10T clutch would put your gearing at 5.4:1 whereas a 12T clutch would give you 4.5:1 gearing. Ideally you want anywhere from 6:1 - 7:1 gearing for most karts but with 13" tires you should be okay with 5.4:1.

Edit: I have a Carter Bros. kart with a stock predator 212, single 12" tall drive tire, 54T on the drive wheel and a 10T clutch. Its pretty quick when you want it to be, but it has bald pizza cutter tires that tear up my dads yard lol

Thanks for the reply. Should I use the same configuration for both karts?

Yes I would try the same configuration on both karts and see how they perform

I just double checked and the Tecumseh is a 60T 5 hp. Should I go with a different configuration?

Both karts have 14 in rear tires. I just double checked. Thanks again.

It should be fine with 60T on the tire. It'll have slightly better "get up and go" with 6:1 gearing
