The whole point of gearing is to make your engine reach a certain speed at certain RPM, very large gearing on the rear axle with give you a lower top speed but more acceleration, a smaller rear sprocket will give you a better top speed at the cost of acceleration. Depending on the tracks length of straights and layout then you will want different gearing.

On your rear axle behind the engine where the chain goes will be a large cog, this is the rear sprocket. If the website says 12/76 the 76 is the cog for the rear, this is replaced by undoing the bolts connecting the sprocket to its carrier and simply replacing it with a different size sprocket (You may need a different size chain to compensate for the difference in cog size, you also will need to move the engine back or forward to keep correct tension on the chain.

The 12 in the 12/76 refers to the engine sprocket, I wouldn't both about changing this in the mean time, however this is basicly just another sprocket you can change that thus changes the range of rear sprockets you need.

In the wet you would normally add 6 teeth on the rear sprocket due to the fact you arn't going so fast.
