@ 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
motorcycle a lockout system to as-
sist the operator in fulfilling the re-
sponsibility of retracting the
sidestand. Please check carefully
the operating instructions listed be-
low and if there is any indication of a
malfunction, return the motorcycle
to a Yamaha dealer immediately for
repair. @

Fuse replacementThe fuse box is located under the rider
seat and the main fuse case is at-
tached to the starter relay. If any fuse is
blown, turn off the main switch and the
switch of the circuit in question. Install a
new fuse of specified amperage. Turn
on the switches and see if the electrical
device operates. If the fuse immediate-
ly blows again, consult a Yamaha deal-
er. It is recommended that the main
fuse be replaced by a Yamaha dealer.

CAUTION:@ Do not use fuses of higher amper-
age rating than those recommend-
ed. Substitution of a fuse of
improper rating can cause extensive
electrical system damage and pos-
sibly a fire. @

TroubleshootingAlthough 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.E_4tv_Periodic.fm Page 39 Wednesday, September 1, 1999 11:12 AM
