EBU35271Tail/brake lightThis model is equipped with an LED tail/brake
light, there are no replaceable bulbs.
If the tail/brake light does not come on, check
the fuses, and then have a Yamaha dealer
check the vehicle.EBU32700TroubleshootingAlthough Yamaha vehicles receive an inspec-
tion before shipment from the factory, trouble
may occur during operation. Any problem inthe 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.
WARNING
EWB03450When 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.
