It depends if its indoor or outdoor.

With indoor karts its all to do with keeping the revs up due to them being 4 stroke.

So you want to do as little sliding as possible and use the brake harshly

(depending on the corners) You'll find that theres probably only 1 or 2 that you need to brake on, the rest will be flat or with a feathered throttle.

You'll develop racecraft in your own way, but best bet is to use the racing line, as most people will run wide after most corners leaving room to duck for the inside.

As for bouncing in the seat, I wouldn't really suggest this in indoor karts as the karts are so varied it'll make very little difference, only do it if the engine bogs down, if its a standing start hold the brake and rev the engine, then foot off the brake to get going.

If its outdoor you you're more than likely to use 2 strokes which are easier to drive as its just point and squirt, although once they get out of their rev band you'll need to hop in the seat to get them to pick up quicker.

Apart from that driving is fairly similar, but you can slide a 2 stroke more as there's more power to do so.

HTH

- end of the day though is to have fun, which I'm sure you will!
