To ensure maximum performance, long service, and safe operation, note the following: Tire air pressure

Always check and adjust the tire pressures before operating the motorcycle.

WARNING: Tire inflation pressure should be checked and adjusted when the temperature of the tire equals the ambient air temperature. Tire inflation pressure must be adjusted according to total weight of cargo, rider, passenger, and accessories (fairing, saddlebags, etc. if approved for this model), and vehicle speed.

Basic weight: With oil and full fuel tank	242 kg (534 lb)
Maximum load	194kg (428 lb)
Cold tire pressure	Front	Rear
Up to 90 kg (198 lb) load*	226 kPa (2.3 kg/cm'. 32 psi)	245 kPa (2.5 kg/cm2. 36 psi)
90 kg (198 1b).-Maximum load	245 kPa (2.5 kg/cm2, 36 psi)	284 kPa (2.9 kg/cm2, 42 psi)
High speed riding	245 kPa (2.5 kg/cm2. 36 psi)	284 kPa (2.9 kg/cm2. 42 psi)

Load is the total weight of cargo, rider, passenger, and accessories.

WARNING: Proper loading of your motorcycle is important for the handling, braking, and other performance and safety characteristics of your motorcycle. Do not carry loosely packed items that can shift. Securely pack your heaviest items close to the center of the motorcycle, and destribute the weight evenly from side to side. Properly adjust the suspension for your load, and check the condition and pressure of your tires. NEVER OVERLOAD YOUR MOTORCYCLE. Make sure the total weight of the cargo, rider, passenger, and accessories (fairing, saddlebags, etc. if approved for this model) does not exceed the maximum load of the motorcycle. Operation of an overloaded motorcycle could cause tire damage, an accident, or even injury.

Inspection

Always check the tires before operating the motorcycle. If a tire tread shows crosswise lines (minimum tread depth), if the tire has a nail or glass fragments in it, or if the side wall is cracked, replace the tire.

Minimum tire tread depth (front and rear)

1.0 mm (0.04 in)

WARNING: It is dangerous to ride with a worn-out tire. When a tire thread begins to show lines, replace the tire immediately.

WARNING: This motorcycle is fitted with "V" range tires (for super high speed running). The following points must be observed in order for you to make fully effective use of these tires.

1.      Never fail to use "V" range tires in tire replacement. "S" or "H" tires may have a danger of bursting at super high speeds.

2.      Tires have a relatively low gripping on the road surface when new, so do not allow any new ones to be subjected to load from maximum speed until after approx. 100 km (60 mi.).

3.      Before any high-speed runs, remember to give a sufficient warm-up to the tires.

Steering stem bolt torque: 110Nm (11.0 m-kg, 80 ft lb)

Inspection

1. Remove the rear wheel and both shock absorbers. Grasp the swing arm and try to move it from side to side as shown. There should be no noticeable side play.

2. The swing arm is mounted on tapered bearings. Move the swing arm up and down as shown. The swing arm should move smoothly, without tightness, binding or rough spots that could indicate damaged bearings.

Adjustment

1. Measure the gap between the frame and the swing arm on the left and right sides. There should be not more than 1.6 mm (0.062 in) difference between the left and right gaps.

NOTE: It may be easier to inspect the gap with the rear wheel removed; however, such removal is not necessary.

LESS THAN 1.6 mm (0.062 in) DIFFERENCE BETWEEN A AND B GAPS.

2. If the left and right gaps differ by more than the limit [1.6 mm (0.062 in)] adjust as follows:

a.    Remove the pivot shaft caps from the left and right sides of the swing arm.

b.    Loosen both the left and right pivot shafts lock nuts.

c.    Loosen the pivot shaft on the side of the greater swing arm/frame gap. Loosen only slightly (counterclockwise, approximately one-half turn). After loosening, tighten the opposite pivot shaft (clockwise) to 5 — 6 Nm (0.5 ~~ 0.6 m-kg, 3.6 - 4.3 ft lb).

1. Lock nut 2 Pivot shaft

d.    Measure the gap again between the frame and the swing arm. If the left and right gaps are not within 1.6 mm (0.062 in) of each other, repeat step. c.

e.    When the left and right gaps are adjusted properly, tighten the pivot shaft lock nut.

NOTE: Do not allow the pivot shaft to turn while tightening the lock nut

Pivot shaft lock nut torque: 100 Nm (10 mkg, 72 ft lb).

Removal

1.      Remove the middle gear flange holding bolts.

2.      Remove the rear wheel and shock absorbers. Remove the rear brake assembly.

3.      Remove the final gear assembly.

4.      Remove the swing arm pivot caps, the pivot shafts and the swing arm.

Inspection and lubrication

1. Remove the oil seals and the bearings. Inspect the bearings for pitting or other damage. Make sure that the bearings roll freely. If a bearing is damaged, both bearings and both sets of inner and outer bearing races should be replaced.

CAUTION: Do not use compressed air to spin the bearings dry. This causes damage to the bearing surfaces.

NOTE: When installing new bearings, grease liberally with lithium base, waterproof wheel bearing grease.

2.      Always replace the grease seals when bearings are removed.

3.      Examine the rubber boot for damage. Replace if damaged.

Installation

Installation of the swing arm can be accomplished by reversing the removal procedure. Observe adjustment procedures for obtaining equal frame/swing arm spacing.

CAUTION: A lock washer for left side pivot bolt must be replaced with a new one and the tab should be bent over along the bolt flat after tightening.

REAR SHOCK ABSORBER ("DE CARBON" SYSTEM) Handling notes

WARNING: This shock absorbers are provided with a separate type tank filled with high-pressure nitrogen gas. To prevent the danger of explosion, read and understand the following information before handling the shock absorbers.

The manufacturer can not be held responsible for property damage or personal injury that may result from improper handling.

1.      Never tamper or attempt to disassemble the cylinder or the tank.

2.      Never throw the shock absorber into an open flame or other hight heat. The shock absorber may explode as a result of nitrogen gas expansion and/ or damage to the unit.

3.      Be careful not to damage any part of the gas tank. A damaged gas tank will impair the damping performance or cause a malfunction.

4.      Take care not to scratch the contact surface of the pistion rod with the cylinder; or oil could leak out.

5.      When scrapping the shock absorber, follow the instructions on disposal.

Notes on disposal

Before disposing the shock absorber, be sure to extract the nitogen gas. To do so, drill a 2 — 3 mm (0.08 ~ 0.12 in) hole through the tank at a position 25 ~~ 30 mm (1.0 — 1.2 in) from the bottom end of the tank. At this time, wear eye protection to prevent eye damage from escaping gas and/or metal chips.

Removal and reinstallation

1.      Remove the seat and side covers (Left and right).

2.      Remove the rear stay and rear fairing.

3. Remove the muffler securing bolts and remove the mufflers.

4. Remove the rear shock absorber mounting nuts and standing handle securing bolt. Then, pull out the rear shock absorber from the frame.

5. For reinstallation, reverse the procedure for removal. When installing, observe the specified tightening torque.

Upper (Left and right sides): 30 Nm (3.0 nrvkg. 22 ft-lb)

Bottom (Left and right sides): 30 Nm (3.0 mkg. 22 ft-lb)

Rear stay: 23 Nm (2.3 mkg. 17 ft lb)

Inspection

1.      Check the rod. If it is bent or damaged, replace the shock absorber.

2.      Check for oil leakage. If oil leakage is evident replace the shock absorber.

3.      Operate shock absorber rod to check damping. There should be not noticeable damping as the shock extends.

Cable maintenance

NOTE: See Maintenance and Lubrication intervals charts. Cable maintenance is primarily concerned with preventing deterioration through rust and weathering and providing proper lubrication to allow the cable to move freely within its housing. 

WARNING: Cable routing is very important. For details of cable routing, see the cable routing diagrams at the end of this manual. Improperly routed or adjusted cables may make the motorcycle unsafe for operation.

1.      Remove the cable.

2.      Check for free movement of cable within its housing. If movement is obstruced, check for fraying or kinking of the cable strands. If damage is evident, replace the cable assembly.

3.      To lubricate the cable, hold it in a vertical position. Apply lubricant to the uppermost end of cable. Leave it in the vertical position until lubricant appears at the bottom. Allow any excess to drain and reinstall the cable.

NOTE: Choice of lubricant depends upon conditions and preferences. However, a semi-drying chain and cable lubricant will perform adequately under most conditions.

Throttle maintenance

1.      Remove the Phillips head screws from throttle housing assembly and separate the two halves of housing.

2.      Disconnect the cable end from the throttle grip assembly and remove the grip assembly.

3.      Wash all parts in a mild solvent and check all contact surfaces for burrs or other damage. (Also clean and inspect right-hand end of the handlebar.)

4.      Lubricate all contact surfaces with a light coat of lithium soap base grease and reassemble.

NOTE: Tighten the housing screws evenly to maintain an even gap between the two halves.

5.      Check for smooth throttle operation and quick spring return when released and make certain that the housing does not rotate on the handlebar.
