Air trapped in the brake fluid circuit acts like a cushion to absorb a large proportion of the pressure developed by the master cylinder and thus interferes with the full braking performance of the brake caliper. The presence of air is indicated by “sponginess” of the brake lever and also by lack of braking force. Considering the danger to which such trapped air exposes the machine and rider, it is essential that after remounting the brake and restoring the brake system to the normal condition, the brake fluid circuit be purged of air in the following manner:
Caution handle brake fluid with care: the fluid reacts chemically with paint, plastic, rubber materials, etc. |
Front brake
Note if air is trapped in the master cylinder, bleed air from the master cylinder first in the same manner as follows. Refer to “front brake master cylinder assembly removal and installation” . |
Note while bleeding the brake system, replenish the brake fluid in the reservoir as necessary. Make sure that there is always some fluid visible in the reservoir. |
Tightening torque air bleeder valve (front caliper): 7.5 N·m (0.75 Kgf-m, 5.5 Lbf-ft)
Rear brake
Note the difference of bleeding operation from the front brake is that the rear master cylinder is actuated by a pedal. |
Tightening torque air bleeder valve (rear caliper): 6 n·m (0.6 Kgfm, 4.5 Lbf-ft)
Carrying a passenger
Before you invite someone to be a
passenger on your motorcycle,
you need to be thoroughly familiar
with motorcycle operation. Adjust
tire pressures and suspension
according to the tire pressure
and loading section and the suspension
section of this manual.
The passenger should always

Regulator / rectifier inspection
Inspect the regulator/rectifier in the following procedures:
turn the ignition switch off.
Disconnect the regulator/rectifier couplers. Refer to “regulator /
rectifier removal and installation” .
Measure the voltage between the terminals using the multi-circuit
tester ...
