LUBRICATING THE THROTTLE
1. Remove:
• Cap cover "1"
• Throttle cable cap "2"
2. Apply:
• Lithium soap base grease
On the throttle cable end "a", tube
guide cable winding portion "b"
and roller sliding surface "c".

CLEANING THE AIR FILTER
ELEMENT
Proper air filter maintenance is the
biggest key to preventing premature
engine wear and damage.
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.
1. Remove:
• Seat
• Fitting bolt "1"
• Washer "2"
• Air filter element "3"
• Air filter guide "4"2. Clean:
• Air filter element
Clean them with solvent.
After cleaning, remove the remaining
solvent by squeezing the element.
• Do not twist the element when
squeezing the element.
• Leaving too much of solvent in
the element may result in poor
starting.
3. Inspect:
• Air filter element
Damage →Replace.
4. Apply:
• Foam-air-filter oil or equivalent oil
to the element
Squeeze out the excess oil. Element
should be wet but not dripping.
5. Install:
• Air filter guide "1"
Align the projection "a" on filter guide
with the hole "b" in air filter element.
6. Apply:
• Lithium soap base grease
On the matching surface "a" on air
filter element.7. Install:
• Air filter element "1"
• Washer
• Fitting bolt
Align the projection "a" on filter guide
with the hole "b" in air filter case.
CHECKING THE TRANSMISSION
OIL LEVEL
1. Start the engine, warm it up for
several minutes and wait for five
minutes.
2. Place the machine on a level
place and hold it up on upright po-
sition by placing the suitable
stand under the engine.
3. Check:
• Transmission oil level
Transmission oil level checking
steps:
a. Remove the oil check bolt "1".
b. Inspect the oil level.
Be sure the machine is positioned
straight up when inspecting the oil
level.
Never attempt to remove the oil
check bolt just after high speed
operation. The heated oil could
spout out, causing danger. Wait
until the oil cools down.
Oil flows out → Oil level is correct.
Oil does not flow out → Oil level
is low. Add transmission oil until
oil flows out. Throttle cable cap:

BLEEDING THE HYDRAULIC
BRAKE SYSTEM
Bleed the brake system if:
• The system has been disassem-
bled.

A dangerous loss of braking per-
formance may occur if the brake
system is not properly bled.

• Diaphragm
• Reservoir float (front brake)
• Protector (rear brake)
2. Bleed:
• Brake fluid
Air bleeding steps:

ervoir.
b. Install the diaphragm. Be careful
not to spill any fluid or allow the
reservoir to overflow.
c. Connect the clear plastic tube "2"
tightly to the caliper bleed screw
"1". Oil check bolt:

CHECKING THE TIRE PRESSURE
1. Measure:
• Tire pressure
Out of specification → A d j u s t .
• Check the tire while it is cold.
• Loose bead stoppers allow the tire
to slip off its position on the rim
when the tire pressure is low.
• A tilted tire valve stem indicates that
the tire slips off its position on the
rim.
• If the tire valve stem is found tilted,
the tire is considered to be slipping
off its position. Correct the tire posi-
tion.

SPOKES
The following procedure applies to all
of the spokes.
1. Check:
•Spoke
Bend/damage → Replace.

Be sure to retighten these spokes be-
fore and after break-in.
CHECKING THE WHEELS
