Further safe-riding points
•Be sure to signal clearly when making turns.
•Braking can be extremely difficult on a wet road. Avoid hard braking, because the scooter could slide.
Apply the brakes slowly when stopping on a wet surface.
•Slow down as you approach a corner or turn. Once you have completed a turn, accelerate slowly.
•Be careful when passing parked cars. A driver might not see you and open a door in your path.
•Railroad crossings, streetcar rails, iron plates on road construction sites, and manhole covers become
extremely slippery when wet. Slow down and cross them with caution. Keep the scooter upright, otherwise
it could slide out from under you.
•The brake pads could get wet when you wash the scooter. After washing the scooter, check the brakes
before riding.
•Always wear a helmet, gloves, trousers (tapered around the cuff and ankle so they do not flap), and a
bright colored jacket.
•Do not carry too much luggage on the scooter. An overloaded scooter is unstable.

Troubleshooting
Although Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition systems,
for example, can cause poor starting
and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems
yourself. However, should your scooter
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the scooter
properly.
Use only genuine Yamaha replacement
parts. Imitation parts may look like
Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
