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.
Throttle grip free play adjustment steps:
Turning in: Free play is increased.
Turning out: Free play is decreased.
●
Tighten the locknuts.
NOTE:
Before adjusting the throttle cable free play,
the engine idle speed should be adjusted.
●
Loosen the locknut 1 on throttle cable.
●
Turn the adjuster 2 in or out until the
specified free play is obtained.
WARNING
After adjusting, turn the handlebar to
right and left and make sure that the
engine idling does not run faster.
