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 a 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 engin
e to seize. However a mixture that is too rich can choke the engine and effect 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 means 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.
