Speed limiter
The speed limiter keeps the throttle from fully
opening, even when the throttle lever is
pushed to the maximum. Screwing in the ad-
juster limits the maximum engine power avail-
able and decreases the maximum speed of the
ATV.
WARNING
Improper adjustment of the speed limiter and
throttle could cause throttle cable damage or
improper throttle operation. You could lose
control, have an accident or be injured. Do not
turn the speed adjuster out more than 12 mm
or the throttle cable could be damaged. Al-
ways make sure the throttle lever free play is
adjusted to 3 ~ 5 mm. See page 8-57.
