I HAVE ABOUT A 60 TOOTH SPROCKET NOT EXACTLY SURE HOW MANY BUT COUNTED ABOUT 60 I WANT TO MAKE MY GO KART GO FASTER WHAT SIZE SPROCKET WOULD U RECOMMEND AND IF I GET A SPROCKET DO I NEED TO CHANGE ANYTHNG ELSE SUCH AS A CHAIN OR THE SPROCKET FOR MY TORQUE CONVERTER AND SO ON THANKS

 

i bigger sproket on the front will make it go faster as well as a samller sproket on the back will, you might have to take a link out of the chain if you change size majorly but try it first you might not have to

 

Think of it like the gears on a bicycle.

1 - larger sprocket on the front, or smaller sprocket on the back will result in better top speed. The engine will have to work harder to get the machine up to speed and you will lose low end grunt.

2 - smaller sprocket on the front, or larger sprocket on the rear will lower the top speed. The engine won't have to work so hard and you will have better low end power.

There is a trade-off between good power for take-off, hill climbing, getting up to speed etc, and top end. You can have a really fast machine but it takes forever to get up to speed because it has no power. Don't make drastic changes in sprocket sizes. Mild size changes make a big difference.

When I built my first go-cart it was geared too high. Out on the paved road it was slow to pickup speed, but would really move once you got it going. On the grass it would barely move at all. I increased the size of the rear sprocket to get more power. Then it ran great in the grass. The top end wasn't as good on the pavement but it was much better overall.

The chain length may have to be modified depending on how big a change in sprocket size and how much adjustment you have.

Experiment until you get it right.
