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.

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.
