The Mini Moto is a modest scale replica of the Globe 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. But how much do you know your mini moto? In this part I will underline the finer factors of the elements that make these speeds attainable.

The Two Stroke Engine

The two stroke engine produces more hp per pound than the 4 stroke engine. The two stroke engine consists of 3 moving components, the piston, the rod and the crank. The piston acts as valve that opens and closes the intake and exhaust ports that are positioned on the walls of the cylinder. As opposed to the four stroke engine that fires only every single other time of the pistons motion, the two stoke engine fires each time the piston reaches the best of its travel. This indicates that the time spent generating power is doubled in the two stroke engine than that of the 4 stroke engine, as there is no engine coasting for the duration of passive cycles. This is the major reason that the two stroke engine can rev a lot more extremely and make more energy (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 while in use.

99% of all starting difficulties are caused by fuel problems. These can stem from poor or old fuel and improperly mixed fuel (please see mixing chart). Do not use fuels that contain alcohol, as the can lead to you bike to run 'lean'. Be advised some racing fuels consist of alcohol and are best avoided... We suggest that you use regular petrol for a garage and good quality two stroke oil.

A mixture that is too lean i.e. not enough two stroke oil can damage your mini moto's engine as the moving parts are not effectively lubricated. This can lead to the engine to seize. However a mixture that is as well rich can choke the engine and influence the overall performance and trigger starting issues. You can tell if your mini moto is running also richly by the plumes of white smoke coming out of the exhaust and the lack of performance. A wealthy mixture (25:1) is required to lubricate the engine for the duration of the 'run in' period you may possibly expertise a lack of efficiency for the duration of this period. The pocket bike might run much more slowly and acceleration can be sluggish, nevertheless when you alter to a mixture of 50:1 you will truly notice a difference. The leaner mix ignites in the combustion chamber quicker and with a more explosive force than the richer mix. This means greater revs which imply much more power and acceleration.

We advocate that a fuel mixture of 25:1 is used to 'run in' you mini moto, and a mixture of 50:1 is employed thereafter.

'Running in'

Your mini moto must be 'run in' for the first 3-four tanks of fuel. During this period we advocate that you use a fuel mixture of 25:1. This means a mixture that is produced up of 25 parts petrol to 1 element of two stroke oil. In the course of the 'running in' period be careful to not rev the engine to its maximum as this can damage the engine. The 'running in' period will permit the moving parts to turn out to be nicely oiled and the clutch and brakes to 'bed' themselves in. Right after you have run the minimoto on this fuel mixture for three-4 tanks, verify the chain and tighten accordingly, verify the tire pressure, tighten the bolts on the brakes, forks and wheels. You may also need to have to readjust the throttle settings to allow for the greater revs that shifting to a leaner fuel mix generates. The bike should now be prepared for a fuel mixture of 50:1. click here
