Troubleshooting
Although Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition sys-
tems, for example, can cause poor
starting and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your scooter
require any repair, take it to a Yamaha
dealer, whose skilled technicians
have the necessary tools, experience,
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
When checking the fuel system, do
not smoke, and make sure there
are no open flames or sparks in the
area, including pilot lights from
water heaters or furnaces. Gasoli-
ne or gasoline vapors can ignite or
explode, causing severe injury or
property damage.
