ROUTINE MAINTENANCE AND SERVICING
INTERVAL: 1999 and 2000 models, every 6000 km (3700 miles)
2001-on models, every 10,000 km (6000 miles)
- The suspension components must be maintained in top operating condition to ensure rider safety. Loose, worn or damaged suspension parts decrease the motorcycle's stability and control.
- While standing alongside the motorcycle, apply the front brake and push on the handlebars to compress the forks several times.
Check that they move up and down smoothly without binding. If binding is felt, the forks should be disassembled and inspected (see Chapter 6).
- Inspect the fork tubes for signs of scratches, corrosion and pitting, and oil leakage. Displace the stoneguard from the top of the fork slider, then carefully lever up the dust seals using a flat-bladed screwdriver and inspect the area around the fork seals (see Chapter 6).
Any scratches, corrosion and pitting will cause premature seal failure. If the damage is excessive, new tubes should be installed (see Chapter 6). If oil leakage is evident, new seals must be fitted (see Chapter 6).
- The forks are adjustable for spring pre-load, rebound damping and compression damping and it is essential that both fork legs are adjusted equally.
The spring pre-load setting can be checked by counting the number of grooves visible below the adjuster bolt (see illustration) (see Chapter 6).
Rebound damping and compression damping require the adjusters to be screwed fully in to check the correct setting and then screwed out to reset as required (see Chapter 6).
RADIATOR PRESSURE CAP: CHECK
- If problems such as overheating or loss of coolant occur, check the entire system as described in Chapter 1.
The radiator cap opening pressure should be checked by a Yamaha dealer with the special tester required for the job. If the cap is defective, replace it with a new one.
COOLANT RESERVOIR: REMOVAL AND INSTALLATION
- Remove the lower fairing and the left-hand fairing side panel (see Chapter 8).
- Remove the reservoir cap and pull out the radiator overflow hose (see illustration).
- Unscrew the reservoir mounting bolts and lift the reservoir off the motorcycle, carefully threading the breather hose attached to the filler neck out of its guides (see illustration).
Tip the coolant out of the reservoir into a suitable container.
