Pit Bike Modification Guide
First these bikes have plenty of restrictive components which mean that the pit bicycle can not perform at its best all the time. The most restrictive parts on these bikes are the carburettor and the manifold. A carb can be picked up for as tiny as £40-£50 which is a bargain for the potential power it could give you, and when you have purchased the carb it would be lovely to invest in a performance air filter, which allows more air to flow in to the engine which equals more horsepower!
Next it would be an idea to modify the exhaust to a performance exhaust, this combined with the carb and air filter will mean great power gains. Exhausts can be bought for around £50 off some web-sites but then again a number of these exhausts retail at hundreds of pounds so be sure to shop around before making your purchase.
These two modifications will add low to mid range torque with a lovely benefit to the top finish of the bicycle as well as a tiny increase in overall horsepower.
In a lot of pit bikes there is usually a restrictor in the CDI unit, these are often limited to around 8,500 rpm, if a performance CDI unit is purchased then this will be increased to 10,000 rpm meaning a smoother and more powerful acceleration curve as well as a higher peak meaning better top finish as well.
Adjustments can be made to the gearing of the bicycle as well, in order for you to adjust this depending on the style of track you will be riding on. If you need to make adjustments to the gearing of the bicycle the best thing to do will be to modify the sprockets. Standard sprockets are usually 14 tooth on the front, with a 37-40 tooth sprockets on the back.
Changing the front sprocket with a larger four will result in better top finish, as well as a smaller rear sprocket will have the same effect, however acceleration will be lost when top finish is gained and vice versa.
