EVU01010TroubleshootingAlthough Yamaha vehicles receive an inspec-
tion before shipment from the factory, trouble
may occur during operation. Any problem in
the fuel, compression, or ignition systems can
cause poor starting and loss of power. The
troubleshooting chart describes a quick, easy
procedure for making checks. If your vehicle
requires any repair, take it to a Yamaha deal-
er.
The skilled technicians at a Yamaha dealer-
ship have the tools, experience, and know-
how to properly service your vehicle. Use only
genuine Yamaha parts on your vehicle. Imita-
tion parts may look like Yamaha parts, but
they are often inferior. Consequently, they
have a shorter service life and can lead to ex-
pensive repair bills.
Tightening torques:
Panel nut: 7 Nm (0.7 m·kgf, 5.1 ft·lbf)
Panel rear bolt: 4.0 Nm (0.40 m·kgf, 2.9 ft·lbf)
