Periodic Maintenance Procedures

Oil Filter Replacement

•Drain the engine oil (see Engine Oil Change).

•Remove the oil filter [A] with the oil filter wrench [B].

Special Tool - Oil Filter Wrench: 57001-1249

•Replace the filter with a new one.

•Apply grease to the gasket [A] before installation.

•Tighten the filter with the oil filter wrench.

Special Tool - Oil Filter Wrench: 57001-1249

Torque - Oil Filter: 17 N·m (1.7 kgf·m, 13 ft·lb)

NOTE

○Hand tightening of the oil filter can not be allowed since it does not reach to this tightening torque.

•Pour in the specified type and amount of oil (see Engine Oil Change).

PERIODIC MAINTENANCE 2-57

Periodic Maintenance Procedures

Brake Hose and Pipe Replacement

CAUTION

Brake fluid quickly ruins painted plastic surfaces; any spilled fluid should be completely washed away immediately.

•Remove:

Upper Fairing Assembly (see Upper Fairing Assembly Removal in the Frame chapter)

Brake Hose Fitting Bolt [A]

Brake Hose Banjo Bolts [B] Bolt [C]

•When removing the brake hoses [D], note the following. ○Take care not to spill the brake fluid on the painted or

plastic parts.

○Temporarily secure the end of the brake hose to some high place to keep fluid loss to a minimum.

○Immediately wash away any brake fluid that spills.

•When installing the brake hoses, note the following. ○Avoid sharp bending, kinking, flatting or twisting, and run

the hoses according to Cable, Wire, and Hose Routing section in the Appendix chapter.

○There are washers on each side of the brake hose fitting. Replace them with new ones.

○Tighten:

Torque - Brake Hose Banjo Bolts: 25 N·m (2.5 kgf·m, 18 ft·lb)

•Fill the brake line after installing the brake hose (see Brake Fluid Change).

Brake Fluid Change

NOTE

○The procedure to change the front brake fluid is as follows. Changing the rear brake fluid is the same as for the front brake.

2-58 PERIODIC MAINTENANCE

Periodic Maintenance Procedures

•Level the brake fluid reservoir.

•Remove: Screw [A] Stopper [B]

Front Brake Reservoir Cap [C] Diaphragm Plate

Diaphragm

•Remove the rubber cap [A] from the bleed valve on the caliper.

•Attach a clear plastic hose [B] to the bleed valve, and run the other end of the hose into a container.

•Fill the reservoir with fresh specified brake fluid.

•Change the brake fluid.

○Repeat this operation until fresh brake fluid comes out from the plastic hose or the color of the fluid changes.

1.Open the bleed valve [A].

2.Apply the brake and hold it [B].

3.Close the bleed valve [C].

4.Release the brake [D].

NOTE

○The fluid level must be checked often during the changing operation and replenished with fresh brake fluid. If the fluid in the reservoir runs out any time during the changing operation, the brakes will need to be bled since air will have entered the brake line.

○Front Brake: Repeat the above steps for the other caliper.

•Remove the clear plastic hose.

•Install the diaphragm and reservoir cap.

•Follow the procedure below to install the front brake fluid reservoir cap correctly.

○First, tighten the front/rear brake fluid reservoir cap [B] clockwise [C] by hand until slight resistance is felt indicating that the cap is seated on the reservoir body, then tighten the cap an additional 1/6 turn [D] while holding the brake fluid reservoir body [A].
