B. Tire pressure measurement
WARNING
This model is equipped with low pressure tires.
Pay attention to the following points:
Recommended tire pressure:
Front: 35 kPa (0.35 kgf/cm
2
, 5.0 psi)
Rear: 30 kPa (0.30 kgf/cm
2
, 4.3 psi)
Maximum vehicle load: 220 kg (485 lbs)
Tire size: Front AT25
×
8–12
Rear AT25
×
10–12
1. Excessive tire pressure [over 250 kPa (2.5 kgf/
cm
2
, 36 psi)] may cause tires to burst. Inflate
tires very slowly. Fast inflation could cause
tire to burst.
2. Too low a pressure [Front: 32 kPa (0.32 kgf/cm
2
,
4.6 psi), Rear: 27 kPa (0.27 kgf/cm
2
, 3.9 psi)] will
cause the rim to dislodge from the tire.
3. Put the same pressure in both rear tires.
Uneven tire pressure will severally affect the
handling.
4. Set tire pressure cold.
C. Fuel draining
1. Remove:
•
Seat
•
Fuel tank side panel (left)
2. Put a rag under the carburetor so fuel does not
contact the crankcase.
3. Loosen the drain screw
1
and drain the standing
fuel.
1. Check:
a. Use an appropriate low-pressure tire gauge. Set
tire pressures to the following specifications:
Reference tire pressure:
Front: 35 kPa (0.35 kgf/cm
2
, 5.0 psi)
Rear:
30 kPa (0.30 kgf/cm
2
, 4.3 psi)
Minimum tire pressure:
Front: 32 kPa (0.32 kgf/cm
2
, 4.6 psi)
Rear:
27 kPa (0.27 kgf/cm
2
, 3.9 psi)
CAUTION:
Never use a tire pressure below minimum
specification. The tire could separate from the
wheel under severe operating conditions.
WARNING
FUEL IS HIGHLY FLAMMABLE:
•
Always turn off the engine when draining.
•
Take care not to spill any fuel on the engine or
exhaust pipe(s)/muffler(s) when draining.
•
Never drain fuel while smoking or in the vicinity
of an open flame.
4. Retighten the drain screw securely and connect
the drain hose

.
5. Install:
•
Fuel tank side panel (left)
•
Seat
D. Engine oil level inspection
1. Place the machine on a level place.
2. Remove:
•
Engine side panel
3. Inspect:
•
Engine oil level
Oil level should be between maximum
1
mark.
Oil level low
→
Add oil to proper level.
NOTE:
Do not screw the dipstick
2
in when inspecting the oil
level.
Recommended engine oil:
At 0 °C (32 °F) or higher:
Yamalube 4 (20W40) or
SAE20W40 type SE/SF motor oil
At –10 °C (14 °F) or higher:
Yamalube 4 (10W30) or
SAE10W30 type SE/SF motor oil
At 0 °C (32 °F) or lower:
SAE5W30 type SE/SF motor oil
Oil quantity (periodic oil change):
Engine:
1.9 L (1.7 Imp qt, 2.0 US qt)
CAUTION:
Do not allow foreign material to enter the
crankcase.
4. Start the engine and let it warm up for several
minutes.
5. Stop the engine and inspect the oil level once
again.
NOTE:
Wait a few minutes until the oil settles before
inspecting the oil level.
WARNING
Never remove the dipstick just after high speed
operation because the heated oil could spurt out.
Wait until the oil cools down before removing the
dipstick.
6. Install:
•
Engine side panel
