Troubleshooting: Scooter Going Slow
a) Motor is bad=THIS IS THE MOST COMMON REASON. Maybe the scooter goes fast if
you lift the back wheel off the ground, but very slow when you sit on it. Sometimes you will
smell the engine burning or you will hear it making a clicking noise.
b) Battery needs to be recharged.
c) Maybe one of the batteries needs to be replaced
– check output of battery with an
electrical meter.
d) Scooter is braking so the brakes need to be adjusted
– If you are simply pushing the
scooter when the ignition switch is turned off and the scooter very hard to push then you
know that the scooter is always braking.
e) The rear chain sprocket and the sprocket on the end of the motor are not properly lined up.
You have to loosen the two outer nuts on the back wheel axle and adjust the back tire so that
the chain lines up straight
f) The chain is too loose or the chain is too tight. Loosen up the nuts on the back axle and
move the back wheel forwards to tighten the chain or backwards to loosen the chain.
g) Make sure the tires have sufficient air but this usually is not the problem.
h) Maybe bearings are worn out. Sometimes you can disconnect the chain and spin the back
wheel and still hear the problem bearing.
Troubleshooting: Grinding Noise In Rear
a) MOST COMMON= motor is making noise
– replace motor. If you take off the chain and
run the scooter, does it still make a noise=if so, then it is definitely the motor.
b) Bearings damaged in rear wheel
– replace bearings.
c) The chain is too loose or the chain is too tight. Loosen up the nuts on the back axle and
move to back wheel to tighten or loosen the chain.
d) The rear chain sprocket and the sprocket on the end of the motor are not properly lined up.
You have to loosen the two outer nuts on the back wheel axle and adjust the back tire so that
the chain lines up straight.
