WARNING
Particularly for a beginner rider, the
speed limiter should be screwed in
completely. Screw it out little by little as
their riding technique improves. Never
remove the speed limiter for a begin-
ning rider.
 For proper throttle lever operation do
not turn out the adjuster more than
25.0 mm (0.98 in). Also, always adjust
the throttle lever free play to 3 ~ 5 mm
(0.12 ~ 0.20 in).
AIR FILTER CLEANING
NOTE:
Proper air filter maintenance is the biggest key
to preventing premature engine wear and
damage.
CAUTION:
Never run the engine without the air filter
element in place; this would allow dirt and
dust to enter the engine and cause rapid
wear and possible engine damage.
