Know your Mini Moro

The Mini Moto is a small scale replica of the World Super Bikes used by the likes of Valentino Rossi and ex champion Carl Fogarty. The Mini Moto comes equipped with either a two stroke air or water cooled engine which are, depending on the model, capable of speeds of up to 60Mph.

In this article I will underline the finer points of the components that make these speeds possible.

The two Stroke Engine

The two stroke engine produces more hp per pound than the four stroke engine. The two stroke engine consists of three moving parts, the piston, the rod and the crank. The piston acts as valve that opens and closes the intake and exhaust ports that are located on the walls of the cylinder. Unlike the four stroke engine that fires only every other time of the pistons movement, the two stoke engine fires every time the piston reaches the top of its travel. This means that the time spent generating power is doubled in the two stroke engine than that of the four stroke engine, as there is no engine coasting during passive cycles. This is the main reason that the two stroke engine can rev more highly and produce more power (for its size) that the four stroke.

Fuel

The two stroke engine needs to be run on a mixture of petrol and two stroke oil. This is so that the engine is kept lubricated whilst in use.

99% of all starting problems are caused by fuel problems. These can stem from bad or old fuel and improperly mixed fuel (please see mixing chart).
Do not use fuels that contain alcohol, as the can cause you bike to run
