Hi guys, i just recently purchased a klipper go kart i have a gx390 motor laying around I'm just trying to figure what size chain to order as well as what type of cc to order I'm not doing a torque converter. the go kart frame has a sprocket on it and chain as well ( i will order new chain just don't know what chain and size to order). The space between the sprocket teeth are 1/2in. help guys!!!! i have pics down below

Ok so, you currently have #4X chain & sprockets; for arguments sake, let's say #40; the issue is that's all we have, we need more data:

How tall are the rear tyres?
How many teeth on the current axle sprocket?

1/2" is usually #40 or 41,
How many teeth on the Sprocket?
You want to divide that count by 6 and get that number of teeth on your clutch.
60/6=10 <<<< Most likely.
