Get To Know Your Mini Moto - Part IV

by: Matt Tong

In the last part of the Get To Know Your Mini Moto series, I will explain how further components of the mini moto contribute to this great little machines.

Throttle

The throttle on your new mini moto is a 'twist grip' style throttle. When you twist the throttle the throttle cable is pulled back revving the engine. It is important to keep this cable free from obstacles and clean. If the throttle begins to feel 'loose' of 'gives', the tension of the cable can be adjusted via the adjusting screw.

Brakes

The brake system comprises of brake levers, brake cables, brake calipers and brake discs.

The brakes on your mini moto are operated by levers found on the handle bars. The right hand brake controls the front brake, and the left controls the back brake. Pulling on the handle pulls the brake cable which in turn pulls the lever located on the bake caliper. This action pushes the brake discs towards each other. This creates friction on the brake disc which slows down or stops the bike.

The brakes can be adjusted in the following ways.

The brake cable can be tensioned using the adjustment screw found on the brake lever. Unscrew the locking nut; twist the screw to reach the desired tension. Re screw the locking nut.

This is a two person job. Adjust the screw on the hand brake so that is at the end of its travel. Undo the clamp that holds the brake cable on the lever located on the brake caliper. One person needs to push the lever forward as far as it will, the second person needs to pull back on the brake cable and re fasten the clamp. The crake cable will now be highly tensioned.

Pull Start

To start the mini moto pull slowly to turn the fly wheel. This pumps some fuel around the engine, which lubricates the moving parts. Pull the pull start firmly in order to start the engine. Important, do not pull the cord to the end of its run as it can break. If the mini moto does not start check the choke and the throttle cable.

Choke

The choke controls the amount of air that is allowed into the air/fuel mix. The choke is adjusted via a lever located on the side and back of the engine. The choke is off when the lever is down, and on when the lever is up. When you start the mini moto the choke should be on, when the mini moto is warm and ready to ride the choke needs to be off.

Carburetor

It is recommended that any adjustments to the carburetor are made by a professional. The carburetor pumps and mixes the fuel and air. The small diaphragms, orifices and ports mix the air and fuel very precisely, this process demands clean fresh fuel.

Jet

The jet can be adjusted by the screw located in the access hole to the right of the choke lever. The jet is adjusted by the manufacture however the conditions of where you wish to ride may be different, which means that you will need to make adjustments. Turning the screw clockwise will make the bike run with a leaner mixture, and counter clockwise will richen the mixture. Only adjust the screw 1 tern at a time and then test the mini moto, this is trail and error. Please note that it is best to find the optimum setting for performance and then run a slightly richer mixture as a mix that is too lean can seize the engine.
