AN IMPORTANT NOTE TO PARENTS:
This ATV is not a toy. Before you let your child
ride this ATV, you should understand the
instructions and warnings in this Owner’s
Manual. Then be sure your child understands
and will follow them. Children differ in skills,
physical abilities and judgement. Some children
may not be able to operate an ATV safely.
Parents should supervise their child’s use of the
ATV at all times. Parents should permit contin-
ued use only if they determine that the child has
the ability to operate the ATV safely.
Your ATV was delivered with an adjustable
speed limiter and also with an air intake restric-
tor plate. Yamaha recommends that all begin-
ners start off with the speed limiter screw turned
in and the air intake restrictor plate installed to
limit the amount of speed 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 ATV.
Parents should decide when to adjust the ATV
for more power as their youngster’s riding skills
improve.
Once the ATV rider can operate with skill at the
top speed permitted by adjusting the speed lim-
iter alone, the air intake restrictor plate can be
removed. Since removal of this plate will result
in a significant increase in power, turn the speed
limiter completely back in again; adjust it out in
stages as you did before.
If your child is a beginner or is inexperienced, he
or she should take a training course.
