Pit bikes can be great fun, and an enjoyable alternative to a conventional bike. They do however have some parts that restrict their day to day performance. And if you are serious about your pit bike's performance, then such restrictions can be a great hindrance. You may wish to travel at high speeds in a safe environment, or perhaps accelerate swiftly for a more enjoyable and efficient ride. This cannot take place if you remain with the stock original parts fitted to your pit bikes.

Parts

The parts of pit bikes that are so restrictive are the carburettor and the manifold. These two parts can be bought for low prices and such replacements could mean a great deal of extra performance for your pit bikes. A carburettor can cost as low an amount as £50; since this cost is so low, it is also advised that you purchase a performance level air filter too, in order to make best use of your newly install part. Increase airflow to the engine will often result in increased performance, which of course is what we are after in this process.

It is additionally a great idea to replace the exhaust system with a performance ...
... level exhaust system; such upgrades can improve pit bikes and their performance a great deal. When added to the performance improvements that you will already have with the newly fitted carburettor and air filter, your overall performance improvements should now be great. These performance exhausts also come in at only £50 or so, meaning that they are another fine and low cost addition to pit bikes.

Both these additional changes to your factory stock bike will make improvements to low and mid range torque, increasing horsepower modestly as well. There are however other improvements that can be made.

Restrictions

Many pit bikes will have been fitted with a restrictor, which limits rpm to around 8,500rpm. This is found in the CDI unit, but with the purchase of a performance level CDI unit, you can possibly remove the limit, allowing rpm's of up to 10,000rpm. This will give far better acceleration, which is not only greater, but more comfortable and with less peaks and falls.

Gear adjustments can also be made, depending on the type of track you are planning on riding the bike on. This can be done by changing the sprockets, which are commonly 14 tooth in the front and 37-40 tooth in the rear. If you replace the front sprockets for larger ones, the front end will be improved. Changing sprockets for smaller rear sprockets will have similar effects; sacrificing acceleration for top end improvements, with the reverse also being true.

In all, modifications to pit bikes can make surprisingly marked improvements in performance that belies the low cost of said improvements.
