Owning a Pocket Bike - Technical
What is the correct fuel mixture?
Fuel mixture is 25:1. Use 95 unleaded fuel pre-mixed with 2 stroke motorcycle oil as indicated on your FREE fuel mixture bottle provided.
Will it operate on pump fuel?
Yes, we recommend 95 unleaded fuel. Use fresh fuel ONLY! Do not use fuel which has been stored for more than 2 weeks. Only mix enough fuel/oil mixture to get you through your outing. This eliminate the need for storage.
What oil is best to use?
A good quality pre-mix 2 stroke motorcycle oil, preferably synthetic. We recommend Castrol 2 Stroke Motorcycle Oil.
What do I use to flush out my tank?
The standard fuel mixture being used or clean 95 unleaded fuel.
How do I break in my new Pocket Bike?
It is recommended to ride the bike in at a slow speed for 2-4 fuel tanks to allow time for the new engine and mechanical parts to loosen, expand and perform better.
What position should the choke be in?
The choke should be in the upward position when doing a COLD START, and it should be in the down position when riding or doing a WARM START. Make sure the fuel tap is OPEN as indicated.
What is the difference between air-cooled and water-cooled?
Water Cooled tends to last longer between rebuilds, because the engine runs cooler – but 40cc class European racers used to favour the air-cooled bikes because they were slightly faster, had less parasitic loss (no water pump drag), and less weight (no pump, radiator, brackets, hoses, overflow bottle, and water).
How do I maintain and keep my bike running smoothly?
- The spark plug must be clean, and must be replaced promptly when signs of wear begin to show. The condition of the spark plug can tell you a lot about the condition of your motor.
- The air filter is used to clean the air going into the motor. Periodic cleaning of this filter is recommended to protect your motor against the damaging effects of dirt and abrasive particulates. Your air filter can be located on the back; it has 2 screws.
- The chain should be lubricated before every ride. The chain should also be checked for tightness on a regular basis. If the chain is too loose, a popping sound can be heard, or the chain will jump off altogether. If the chain is too tight, it will be noisy and bind, this can be felt by pushing the bike with the motor off.
- The carburetor has many adjustments and so we recommend only experienced persons work on it.
- Always check that all your nuts, bolts and clips are tight. Vibration can loosen them over time. We recommend using Loctite on all fasteners.
- Check that your tyre pressure is correct according to the info on the tyre.
- Make sure that your chain is aligned correctly by looking from the rear wheel forward towards the front sprocket. Ensure the chain is running as straight as possible to maximise efficiency and speed. If the chain does not align correctly, it can break or snap under pressure.
- Make sure there are no abrasions on any of the wiring, especially around the kill switch, and that no wiring is near the exhaust
- Always drain the fuel from the tank and carb when the bike will not be in use for a long time.
