Sprocket Size/Gear Ratio

[Shaun78]

I have an 82t sprocket on my rear axle and 11t sprocket on my clutch. I want to make it faster on the straightaways without sacrificing to much on accelerating. What is the best way to accomplish this? It is a racing go kart with a KT 100 engine.

increase clutch tooth count, or decrease rear axle sprocket tooth count (either/or, not both at the same time)

I would just get a rear axle sprocket (assuming its a race kart?) dont these sprockets come split in two so you just unbolt the existing one, then bolt on a new one?

Rear sprocket

Some do mine however is one piece but thanks for the reply. Yes it is a race kart.

Here is a pic of all the sprockets i have and the pipe i was talking about .

Adding one or two teeth on the clutch can be a pretty sizeable difference.

If I was to reduce the rear sprocket, what size would get? 82t - ??? My sprocket is one piece besides the sprocket hub piece.

Are you sure it is 1 piece because 99% of the karts are two piece sprockets with 8 bolts

go slow, 3-4 Teeth will make a noticeable difference already.
usually split sprockets are used, and I'd suggest you'd swap to that;
the hub will most likely take them just as well.
and in case you want to try different set ups, you can easily mount them in the future

You wouldn't notice much difference with an 82, I'd try something in the 72 to 76 tooth range
