Scooter Tuning Overview

Scooter tuning

So you want more power from your scooter. Welcome to the club.

Scooter tuning is very popular throughout the world. A vast array of aftermarket performance parts are available for many applications, from circuit or drag racing to high performance street duties.

Should you start upgrading parts on your scooter? If the scooter is still under warranty, and you want more power then be very careful as performance modifications usually void the warranty. You have been warned!

Also many countries have laws in regards to the top speed or maximum KW output of mopeds (Generally 50cc scooters). Make sure you check this or you could find you’re breaking the law in your country.

If you can’t control your need for power or don’t have a warranty on your scoot – then read on.

Before starting, have a read of our maintenance article and make sure that your scooter is in good working order. No point tuning a scooter that won’t be up for the challenge: If you deem your machine ready then the work can begin!

 

Derestriction

(Mostly applies to 50cc scooters)

Many modern 50cc scooters are restricted. This is usually done to limit the top speed.

This is done by:

  1. Restricting the exhaust pipe.
  2. A washer/ or similar limiting the movement of the variator.
  3. CDI (computer distributed ignition) which limits the maximum rpm of the scooter.

Once you’ve worked out what is restricting the scooter and replaced/or removed that restriction. You should find the bikes full potentional. Be wary of spending hours de-restricting your scooter if you’re planning on further upgrades that will result in restricted parts being binned. It may pay to combine the de-restricting with power upgrades. i.e. instead of spending ages drilling out a restriction in the standard exhaust pipe, replace the entire system with an after market model; the end result will equal more power.

 

Exhaust

This should be one of your first choices when tuning a scooter. This is especially true for a 2-stroke motor. The shape and internal diameter of the exhaust has a large impact on the power of a two-stroke motor. In a four stroke the increase won’t be as pronounced, but still is key part of the tuning process.

 

Intake

There are three parts to the intake of most scooters:

Air filter and box

Manufacturers create scooters that are quiet. They do this at the expense of some power. The engine has to work a little harder to suck the air through a small intake hole, into an air-box, which reduces intake noise and through a foam/paper filter that also removes dirt from the air.

If more power is to be made then more air and more fuel will be required. More fuel means bigger jets in the carburettor; jet size selection depends on level of modification done to the engine.
