become familiar with all controls. If there
is a control or function you do not un-
derstand, ask your Yamaha dealer.

TIP
This model is equipped with a lean angle
sensor to stop the engine in case of a
turnover. To start the engine after a turn-
over, be sure to turn the main switch to
“OFF” and then to “ON”. Failing to do so
will prevent the engine from starting
even though the engine will crank when
pushing the start switch.
