Always use premium unleaded gas: Premium 92 or 94 Octane with the appropriate
fuel/oil mixture as discussed above. (Use fresh gas only. DO NOT use any
gas that has been stored for more than 2 weeks.)
What oil is best to use?
Any good fully synthetic / mineral oil is fine.
What do I use to flush out my tank?
Whatever mixture you plan on using (eg. 25:1 / 50:1) Use the same mixture to
flush out the tank.
What position should the choke be in?
The choke should be in an upward position when you are doing a cold start and a
down position when you are doing a warm start.
How do I Break-in My Pocket Bike??
Start with petrol and oil mixture of 25 parts of petrol to 1 part oil. DO NOT throttle the bike and
do not keep your RPM at a constant speed. Let the bike cool down after every 10 minutes of riding.
When the bike is broken in, like after 4 full tanks, change the petrol and oil mixture to 50 parts to 1.
What is the difference between air-cooled and water-cooled?
Water -cooled tends to last longer between rebuilds because the engine runs at a
cooler temperature. However, some enthusiasts favor the air-cooled bikes because
they could be a bit faster....having less parasitic loss (no water pump drag)
and less weight (no pump, radiator, brackets, hoses, overflow bottle, and
water).
POCKET BIKE
MAINTENANCE
Your new pocket bike will
last longer and perform better if you maintain it using the below information.
Maintenance is crucial to getting the most out of your pocket bike. The
following instructions are for our models, however, most of the principals are
universal and can be utilized on all makes of pocket bikes.
Furthermore, we remind pocket
bike enthusiasts that although pocket bikes are used like toys, they can be
dangerous if not respected. Please follow safe riding practices and ALWAYS wear
protective gear and follow federal, provincial and local laws.
Fuel and Oil Mixture
Information
Your pocket bike uses
2-stroke motor for power. A two-stroke gas motor was chosen for its
excellent power to weight ratio. A two-stroke gas motor does not require
that you ever change the oil, however, it does require that you mix quality
grade 2-stroke oil with the gas prior to filling your scooters gas tank.
This ensures that your gas motor will remain lubricated and give you
reliable service.
To
accomplish this you can buy 2-stroke oil at almost any auto parts store or
hardware store. The oil and gas are the mixed together in a separate
container before filling pocket bikes. The mixture should be done at a 25:1
ratio. Mixing the gas and oil too lean can cause the gas motor to run too
hot resulting in permanent gas motor damage. Mixing the gas and oil too rich
will cause decreased performance and result in a fouled spark plug. By
strictly following the 25:1 ratio you can be assured maximum performance.
Spark Plug Maintenance & Information
The spark plug is a
crucial and vulnerable part on your two-stroke motor. Your spark plug can be
located on the top of the motor under the protective rubber boot. Your
pocket bike comes with a tool kit containing a spark plug wrench for easy
removal.
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 how your motor is
running. The spark plug should be a light brown or golden color. If the
electrode is white, that can be a sign that the scooter is running too hot.
This can be a result of either running too lean (See the Carburetor
section), or that the fuel and oil mixture is too lean (See the Fuel and Oil
mixture section). If you are running too rich then your spark plug may be
black, covered with gas, oil, or carbon.
Another common problem is that the spark plug gets clogged up
with carbon and/or oil and "fouls". This should be checked by assuring the
electrode has a clean gap of . 023 in. If you are having a problem with
fouling, just be sure that the gap, as shown to the right, is clean and free
of obstruction, A small piece of fine grit sandpaper usually works well for
this. New spark plugs can be purchased from us on our parts page, or at
almost any local hardware or small engine parts store.
Air Filter Maintenance & Information
The air filter is used to clean the air going into the gas 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 front of the gas motor and the protective cover
can be removed with one screw.
When the protective cover
is removed the air filter is revealed. You can also see the small workings
of the choke and butterfly valve.
The filter should be free
from dirt and grease and appear clean. If there are contaminants on the
filter it can be cleaned in a container of gas. Allow the filter to dry
before re-installing it.
Chain Maintenance & Information
The chain on your pocket
bike 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 and the pocket bike will jerk under acceleration,
or the chain will just 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.
On pocket bikes there is a chain driven gear reduction, which must also
be lubricated before each ride. This gear reduction chain does is not
adjustable and must be replaced when an unacceptable amount of slack is
present.
Access for lubrication can
easily be obtained through a small lubrication hole on the top of the chain
guard.
When making any adjustments to the chain it is very important to ensure
the chain and sprockets are perfectly aligned. If they are not, the chain
will most certainly come off. To properly align you must get your eye level
with the chain. Make sure that all components are aligned before tightening
the fasteners.
The rear tire held on by
an axle and two locking eyebolts. To adjust, loosen the axle bolts and the
locking nuts. Use the eyebolt nuts to tighten and align the rear scooter
tire. Once the chain is snug and straight tighten the axel nuts. Finally
cinch down the locking nuts on the eyebolts.
Tires Maintenance & Information
The tires on your pocket
bike are tubed or tubeless tires . The tires require about 30 to 35 psi and can be
filled via the valve on the side of the tire. It is very important that the
tires have the proper inflation. Although the pocket bikes have been
prepared to ride once out of the box, due to long shipping distances and
elevation changes we have yet to see one gas powered scooter with the
correct pressure right out of the box. Low tire pressure will make the
scooter feel sluggish and a loss of power will be felt. Remember: Check the correct PSI before pumping in air.
You will notice that the valve on the front tire is turned to the side a
little and is not straight out. This is intentional to keep the valve from
hitting the frame of the scooters as the wheel turns. If the valve is not
angled you will hear a clicking sound every time the tire makes a rotation.
To cure this, let all of the air out of the tire. Hold the tire with one
hand and the rim with the other. Twist the tire one-way and the rim the
other. This will cause the tire to "slip" on the rim and make the valve turn
to one side. Once this is achieved refill the tire to the required PSI.
Different pocket bikes may have different PSI,
please ensure to look at the side of the tire for recommended
PSI.
Throttle Maintenance & Information
There are two main types
of pocket bike throttles. One is a twist type, and the other is a hand
throttle. Although the throttles are different in operation, they are
essentially mechanically the same. When the rider applies the throttle, a
cable carries this motion down to the motor. For continued smooth operation
it is important to keep this cable clean and free of obstructions.
Should the throttle begin to feel loose and sloppy, the slack can be
adjusted on the cable at the handlebars. Simply loosen the lock nut and
adjust the cable tension via the adjustable screw. Once the desired tension
is achieved retighten the lock nut.
Brakes Maintenance & Information
The brake on your pocket
bike is a cable actuated drum brake. This style brake has proven well over
time and is very simple to maintain. The rear brake has two main
adjustments. The easier of the two is the adjustment on the handbrake
itself. This adjustment has two simple steps. To change the tension on the
cable merely back off the locking nut and screw the adjustment screw in or
out accordingly. Once the desired tension is achieved re tighten the locking
nut.
Further adjustment can be made at the drum itself. This task is easiest
with two people. First, loosen the adjustment at the handlebar hand brake
and screw it all the way in. Next go to the rear brake and loosen the Cable
Clamps. Once loose, pull back on the cable and have the second person push
forward on the brake cable lever (push hard, you are pushing against a tight
spring action). While pushing the lever forward and pulling the cable back,
quickly tighten the cable clamps. Additional minor adjustments can be made
where the cable meets the rear brake.
Carburetor Maintenance & Information
The carburetor has many
adjustments on it and it is recommended that experienced persons make these
adjustments only, however we will point out the major points. The carburetor
is responsible for pumping the fuel and mixing it with the air at a precise
measurement. The carburetor does this with very small diaphragms, orifices
and ports, which are easily clogged by contaminants. This is why is
extremely important that you use only clean new fuel mixed with 2-cycle oil
in your pocket bike.
Primer Maintenance & Information
When the pocket bikes are
brand new, been run out of gas, been sitting for a long period or is very
cold, it may be necessary to prime the carburetor before attempting to start
it. This is accomplished with the primer pump bowl located at the bottom of
the carburetor. Simply press and release this pump several times until gas
can be seen flowing through the clear gas return line to the fuel tank. This
will help start the pocket bike under the aforementioned conditions,
however, if this is done once the pocket bikes have warmed up it may induce
flooding.
Jet Maintenance & Information
Due to the fact that the
carburetor mixes the fuel and air at an exact ratio, elevation, temperature,
humidity and other weather related variables could have a detrimental effect
on your pocket bikes performance. The manufacturer pre-adjusts your pocket
bike at near sea level and depending where you live your bike may require
adjustment. The adjustment screw, or "jet", can be located in the access
hole just to the right of the choke lever. Turning the screw clockwise will
lean the mixture while turning the screw counterclockwise will richen the
mixture. It is recommended that the jet be adjusted no more then 1/4 turn at
a time. Test the pocket bike between turns and once peak performance we
achieved we recommend richening the adjustment a 1/8 turn. This is due to
the fact that the leaner the motor is run, the hotter it will get, and this
can induce a possible seizure of the motor from overheating.
Idle Maintenance & Information
If the
pocket bike will not idle or idles too fast, an adjustment screw is provided
next to the choke. Turning this screw clockwise will increase the idle
speed. Turning the screw counterclockwise will decrease the idle speed.
Remember that an idle speed that is too fast can be dangerous.
