Get to know your mini moto part i

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. But how much do you know your mini moto? In this part 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 'lean'. Be advised some racing fuels contain alcohol and are best avoided... We recommend that you use normal petrol for a garage and 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 properly lubricated. This can cause the engine to seize. However a mixture that is too rich can choke the engine and affect the performance and cause starting problems. You can tell if your mini moto is running too richly by the plumes of white smoke coming out of the exhaust and the lack of performance. A rich mixture (25:1) is needed to lubricate the engine during the 'run in' period; you may experience a lack of performance during this period. The pocket bike may run more slowly and acceleration can be sluggish, however when you change to a mixture of 50:1 you will really notice a difference. The leaner mix ignites in the combustion chamber faster and with a more explosive force than the richer mix. This means higher revs which mean more power and acceleration. We recommend that a fuel mixture of 25:1 is used to 'run in' you mini moto, and a mixture of 50:1 is used thereafter. 'Running in' Your mini moto should be 'run in' for the first 3-4 tanks of fuel. During this period we recommend that you use a fuel mixture of 25:1. This means a mixture that is made up of 25 parts petrol to 1 part of two stroke oil. During 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 allow the moving parts to become well oiled and the clutch and brakes to 'bed' themselves in. After you have run the minimoto on this fuel mixture for 3-4 tanks, check the chain and tighten accordingly, check the tire pressure, tighten the bolts on the brakes, forks and wheels. You may also need to readjust the throttle settings to allow for the higher revs that changing to a leaner fuel mix produces. The bike should now be ready for a fuel mixture of 50:1.

Oem or aftermarket detailed version

You may be needing of an OEM motorcycle part or may be not. Read on to know more. OEM part is short for Original Equipment Manufacturer part. At first sight, it may be understood as originally manufactured per se. However, many motorcycle manufacturers do not really manufacture every motorcycle part of their bikes. They have some parts designed and manufactured by outside companies. After manufacturing, they will now install it to their bikes and will be labeled as OEM. Purchasing OEM motorcycle parts means buying the exact or same original part your bike manufacturer used to assemble their bikes. In purchasing, be sure that you will get same performance than that installed in your bike. No less. When it comes to price, OEM parts are usually expensive than aftermarket motorcycle parts. However, there are instances when it is on the contrary. Sellers, most of the time, say that OEM parts are of higher quality compared to aftermarket parts. This is a common scenario in a motorcycle parts store but the statement may not be always right. Another circumstance about motorcycle parts is the transformation. Say an OEM part can eventually become an aftermarket OEM part. What a transformation! The circumstances presented advice you to be extra careful. Caveat emptor, that is. In this regard, it will be best to use OEM parts only within your bike’s guarantee period. Also, have these parts installed by authorized mechanics. This is to make sure that your guarantee will remain valid and subsisting. Aftermarket motorcycle parts, on the other hand, should perform well as OEM. These parts are made by companies other than the original bike manufacturer. You can use these parts when your guarantee period lapses. Some riders have this misconception that aftermarket is always of lower quality. But this is not always true. In fact, aftermarket parts can also be of the same or even higher quality than OEM parts. Carbon fiber, gizmos, titanium and aerospace aluminum parts are some of the materials that make up high performance aftermarket parts. When purchasing motorcycle parts, be sure to get at least the same quality if not better as the OEM part. You can do this by searching and asking. Search the Net and ask your fellow riders and skilled mechanics.
