Sidestand
This model is equipped with an ignition
circuit cut-off system. The motorcycle
must not be ridden when the sidestand
is down. The sidestand is located on
the left side of the frame. (Refer to
page 5-1 for an explanation of this sys-
tem.)
EW000044
This motorcycle must not be operat-
ed with the sidestand in the down
position. If the stand is not properly
retracted, it could contact the
ground and distract the operator, re-
sulting in a possible loss of control.
Yamaha has designed into this mo-
torcycle a lockout system to assist
the operator in fulfilling the respon-
sibility of retracting the sidestand.
Please check carefully the operating
instructions listed below and if there
is any indication of a malfunction,
return the motorcycle to a Yamaha
dealer immediately for repair.

for a sealed-type (MF) battery.
Using a conventional battery
charger will cause battery dam-
age. If you do not have a sealed-
type battery charger, contact
your Yamaha dealer.
lAlways make sure the connec-
tions are correct when reinstall-
ing the battery.

Troubleshooting
Although Yamaha motorcycles receive
a rigid inspection 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 trouble-
shooting chart describes a quick, easy
procedure for making checks.
If your motorcycle requires any repair,
bring it to a Yamaha dealer. The skilled
technicians at a Yamaha dealership
have the tools, experience, and know-
how to properly service your motor-
cycle. Use only genuine Yamaha parts
on your motorcycle. Imitation parts may
look like Yamaha parts, but they are of-
ten inferior. Consequently, they have a
shorter service life and can lead to ex-
pensive repair bills.
