EWB00163Always stop the ATV before changing from

wheel drive than in four-wheel drive in somecircumstances. Changing from two-wheel
drive to four-wheel drive or vice versa while
moving may cause the ATV to unexpectedly
handle differently. This could distract the oper-
ator and increase the risk of losing control and
of causing an accident.EBU18280Throttle lever Once the engine is running, movement of the throt-
tle lever will increase the engine speed.
Regulate the speed of the ATV by varying the
throttle position. Because the throttle is spring-
loaded, the ATV will decelerate, and the engine will
return to an idle any time the hand is removed from
the throttle lever.

EBU20910Accessories and loading EBU20920Accessories
Accessories can affect the handling and control of
your ATV. Keep the following in mind when consid-
ering an accessory or operating an ATV which has
accessories.
Choose only accessories designed for your
ATV. Your Yamaha dealer has a variety of gen-
uine Yamaha accessories. Other accessories
may also be available on the market. However,
it is not possible for Yamaha to test all non-
Yamaha accessories, nor control over their qual-
ity or suitability. Choose a genuine Yamaha ac-
cessory, or one that is equivalent in design and
quality.
Accessories should be rigidly and securely
mounted. An accessory which can shift position
or come off while you are riding could affect your
ability to control the ATV.
Do not mount an accessory where it could inter-
fere with your ability to control the ATV. Exam-
ples include (but are not limited to) a heavy or
bulky object attached to the handlebars which
