Maintenance is crucial to getting the most out of your scooters or motorcycles.
The following instructions are for Razorback models however most of the principals are universal and can be utilized
on all makes of gas scooters and motorcycles.
Furthermore we remind gas scooters and motorcycles enthusiasts that
although motorized scooters are toys, they can be dangerous if not respected. Please follow safe riding practices and
ALWAYS wear protective gear.
Gas Scooters Fuel and Oil mixture Information
Your gas scooters
use 2-stroke motor for power. A two-stroke gas motor was chosen for it's 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 gas scooters. The mixture
should be done at a 32:1 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 32:1 ratio you can be assured maximum performance.
Gas Powered Scooters Spark Plug Maintenance and Information
The
spark plug is a crucial and vulnerable part on your fasst two-stroke motor. Your spark plug can be located on the top
of the motor under the protective rubber boot. Motorized scooters come 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 scooters parts
store.
Gas Powered Scooters Air Filter Maintenance and 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.
Gas Powered Scooters Chain Maintenance and Information
The
chain on your gas powered scooters 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 gas powered scooter 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 scooter with the motor off.
On the 22.5cc gas powered scooters 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.
Sometimes it is difficult to get the chain straight due to the fact that
the motor and rear wheel sprocket aren't aligned. If this occurs simply turn the gas powered scooter on its side, loosen
the three motor mounting bolts, and the motor can be easily slid to either side to compensate for any misalignment.
