2011 YAMAHA PW50 service

INTRODUCTIONAN IMPORTANT NOTE TO PARENTS:
This motorcycle is not a toy. Before you let your child ride this motorcycle, you should understand the instructions and warn-
ings in this Owner’s Manual. Then be sure your child understands and will follow them. Children differ in skills, physical abil-
ities, and judgment. Some children may not be able to operate a motorcycle safely. Parents should supervise their child’s
use of the motorcycle at all times. Parents should permit continued use only if they determine that the child has the ability to
operate the motorcycle safely.
Your motorcycle is equipped with an adjustable speed limiter and a power reduction plate. Yamaha recommends that all be-
ginners start off with the speed limiter adjusting screw turned in and the power reduction plate installed in the exhaust man-
ifold to limit the power available while they learn. The limiter screw may be gradually turned out to increase maximum speed
as the beginner becomes more familiar with operating the motorcycle. Parents should decide when to adjust the motorcycle
for more power as their youngster’s riding skills improve. Once the rider can operate with skill at the top speed permitted by
adjusting the speed limiter alone, the power reduction plate can be removed. Since removal of this plate will result in a sig-
nificant increase in power, turn the speed limiter back in again; adjust it out in stages as you did before.
Motorcycles are single track vehicles. Their safe use and operation are dependent upon the use of proper riding
techniques as well as the expertise of the operator. Every operator should know the following requirements before
riding this motorcycle.
He or she should:

Obtain thorough instructions from a competent source on all aspects of motorcycle operation.


Observe the warnings and maintenance requirements in this Owner’s Manual.


Obtain qualified training in safe and proper riding techniques.


Obtain professional technical service as indicated in this Owner’s Manual and/or when made necessary by mechanical
conditions.

Periodic inspection, adjustment, and lu-
brication will keep your vehicle in the
safest and most efficient condition pos-
sible. Safety is an obligation of the vehi-
cle owner/operator. The most important
points of vehicle inspection, adjust-
ment, and lubrication are explained on
the following pages.
WARNING
EWA10321
Failure to properly maintain the ve-
hicle or performing maintenance ac-
tivities incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle ser-
vice, have a Yamaha dealer perform
service.
WARNING
EWA15121
Turn off the engine when performing
maintenance unless otherwise
specified.


A running engine has moving
parts that can catch on body
parts or clothing and electrical
parts that can cause shocks or
fires.


Running the engine while ser-
vicing can lead to eye injury,
burns, fire, or carbon monoxide
poisoning – possibly leading to
death. See page 2-1 for more in-
formation about carbon monox-
ide.WARNING
EWA15460
Brake discs, calipers, drums, and
linings can become very hot during
use. To avoid possible burns, let
brake components cool before
touching them.
EAU17302
Emission controls not only function to
ensure cleaner air, but are also vital to
proper engine operation and maximum
performance. In the following periodic
maintenance charts, the services relat-
ed to emissions control are grouped
separately. These services require
specialized data, knowledge, and
equipment. Maintenance, replacement,
or repair of the emission control devic-
es and systems may be performed by
any repair establishment or individual
that is certified (if applicable). Yamaha
dealers are trained and equipped to
perform these particular services.

Troubleshooting Although Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur dur-
ing operation. Any problem in the fuel,
compression, or ignition systems, for
example, can cause poor starting and
loss of power.
The following troubleshooting chart
represents a quick and easy procedure
for checking these vital systems your-
self. However, should your motorcycle
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the motorcycle
properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look like
Yamaha parts, but they are often inferi-
or, have a shorter service life and can
lead to expensive repair bills.
WARNING
EWA15141
When checking the fuel system, do
not smoke, and make sure there are
no open flames or sparks in the ar-
ea, including pilot lights from waterheaters or furnaces. Gasoline or
gasoline vapors can ignite or ex-
plode, causing severe injury or
property damage.U5PG8AE0.book Page 23 Thursday, April 8, 2010 8:37 AM
