FINAL GEAR OIL Oil Level Measurement

1.  Place the motorcycle on a level area and place on its centerstand.

2.  Remove the oil filler cap

3.  Observe the  oil level (2) and add oil if necessary.


NOTE:
Oil level must be up to the brim of the filler hole.

CAUTION:
Be sure that no foreign material enters the final gear case.

Gear Oil Replacement

1.  Place a receptacle under the final gear case.

WARNING:
Spilling oil on the tires  or on the ground under the tires will reduce traction and may result in an accident. Use a funnel, stiff piece of card, plastic or similar to ensure all oil is directed into the receptacle.

2.  Remove the filler cap and drain plug (1). Drain final gear oil into the receptacle.

3.  Re-install the drain plug. Torque to 23 Nm (2.3 m-kg, 17 ft-lb).

4. Fill the gear case to the specified level.

Oil Capacity: 0.20 L (0.18 Imp qt, 0.21 US qt)

NOTE:.
If desired, an SAE 80W90 Hypoid gear oil may be used for all conditions.

5. Install the filler cap. Torque cap to  23 Nm (2.3 m-kg, 17 ft-lb)

AIR FILTER

1. Remove the seat, fuel tank and rubber cover.

2. Remove the air filter cover (1)

3.  Eliminate dust using compressed air.

Note:
Blow out dust from the inside out.

4.  Inspect the element and replace if damaged. 

CAUTION:
The engine should never be run without the air/filter element installed; excessive piston and/or cylinder wear may result.

5. Install the element back in the airbox. Installation steps are the reverse of removal.

CAUTION:
Make sure the element cover fits into the corresponding filter case edge.

FRONT FORK OIL CHANGE

WARNING:
Securely support the motorcycle so there is no danger of it falling over.

1. Place a suitable stand under the engine to raise the front wheel off the ground.

2. Remove the air valve cap (1)

NOTE:
Keep the valve (2) open by pressing it for several seconds so that the air can be let out of the inner tube.

3.  Loosen the inner tube pinch bolt (1)

4.  Remove the cap bolt (2)

5. Remove the drain screw (1). Drain the fork oil.

WARNING:
Do not allow any oil to contact the disc brake components. If oil is discovered, be sure to remove it, otherwise diminished braking capacity and damage to the rubber components of the brake assembly will occur.

6. Inspect:

•O-ring (1) (Cap-bolt) 
•Gasket (Drain bolt screw) 

Replace if worn or damaged.

7.  Install the drain screw

8.  Fill the front forks.

Each Fork:

389 cm3 (13.7 Imp oz, 13.2 US oz)

After filling purnp the forks slowly up and down to distribute the oil. 

9. Tighten the cap-bolt and pinch bolt

Cap Bolt: 23 Nm (2.3m.kg, 17 ft-lb) 

Pinch Bolt: 20 Nm (2.0 m-kg, 14 ft-lb)

10.  Pressurize Fork with specified amount of air. Refer to "Front fork adjustment".

11.  Install the fork cap

Maximum Air Pressure: 118 kPa (1.2 kg/,cm 17.1 psi) Do not exceed this amount.

FRONT FORK ADJUSTMENT

1. Place motorcycle on centerstand, then elevate front wheel.

NOTE:
Be sure there is no weight on the front end of the motorcycle and the fork tube is at room temperature when air pressure is checked and adjusted.

2.  Remove the fork cap

3.  Measure the air pressure with an air gauge and adjust as needed.

NOTE:
Increased air pressure causes stiffer suspension; decreased pressure causes softer suspension.

CAUTION:
Do not use a high pressure air supply that will overpressurize the forks faster than the operator can control. Use only a manual pump or low pressure supply to avoid seal damage.

Air Pressure Adjustment

To increase air pressure

Use manual air pump or pressurized air supply.

To decrease air pressure

Release air by pushing valve pin.

Standard Air Pressure: 39.2 kPa (0.4 kg/cm3, 5.7 psi)

Maximum Air Pressure: 118 kPa (1.2 kg/cm2, 17.1 psi)

Minimum Air Pressure: Zero

REAR SHOCK ABSORBER ADJUSTMENT

If the spring seat is raised, the spring becomes stiffer, and if lowered, it becomes softer.

Standard Position: A       A. - Softest E. - Stiffest

WARNING:
Always adjust each shock absorber to the same setting. Uneven adjustment can cause poor handling and loss of stability.

TUBELESS TIRES AND ALUMINUM WHEELS

WARNING:
 Always inspect aluminum wheels before a ride.
Do not attempt any repairs to the wheel; replace any defective wheel.
Do not attempt to use tubeless tires on a wheel designed for use with tube-type tire only. Tire failure and subsequent personal injury may result from sudden deflation.

• Be sure to install the proper tube when using tube-type tires.

• New tires have a relatively poor adhesion on the road surface so do not allow them to be subjected to high speed load from maximum speed until after a break-in run of approx. 100 km (60 mi).

• Always use the correct tire inflation pressure according to the operating conditions.
