Been playing around with the gearing for my lads kart. Is it better to have a larger or smaller engine sprocket, or does it make no difference if the gear ratio is the same.
e.g. If I use a 74 rear sprocket with a 10 engine sprocket that gives basically the same gear ratio as an 81 with an 11. Does it make any difference which combo I use?
This has been debated and the general consensus is that ratio is ratio and that bigger or smaller sprocket doesn’t make a measurable differenc to us kart folks
However, now that I think about it, big sprockets and kerbs aren’t a good fit. So maybe there are times when this matters in terms of not having your chain and sprocket whang kerb.
