TroubleshootingAlthough Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition systems,
for example, can cause poor starting
and loss of power.
The following troubleshooting chart
represents a quick and easy pro-
cedure for checking these vital sys-
tems yourself. However, should your
scooter require any repair, take it to a
Yamaha dealer, whose skilled techni-
cians have the necessary tools, expe-
rience, and know-how to service the
scooter properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
EWA15141
WARNING
When checking the fuel system, do
not smoke, and make sure there
are no open flames or sparks in
