Inspections III and IV
Check battery acid level and add distilled water if necessary; inspect battery terminals and clean and grease them if necessary.
Warning: Battery acid is highly caustic. Protect the eyes, face and hands and also paintwork and clothing.
Checking battery acid level
Note: The battery must be removed for checking the acid level.
- Place motorcycle on its centre stand.
- Open the seat at the front.
Caution: Avoid damage to fuel tank, wiring and hoses. Disconnect the battery only when the ignition is switched off.
To avoid short-circuits: Disconnect negative battery lead (—) first, then positive (+) lead.
- Disconnect negative battery lead (3) from the battery and isolate.
- Open cover cap for the positive battery terminal, disconnect positive battery lead and isolate.
- Release the fasteners (1) on the battery tray (2). Remove the battery tray.
- Lift the battery off the holder together with the battery breather hose and place the battery down on a level surface.
- Clean battery terminals and lubricate with acidproof grease.
- Check battery acid level.
Adding distilled water
- Remove the battery.
- Set the battery down on a level surface.
- Open the 6 battery caps with a screwdriver.
Caution: Use only distilled water to top up the acid level in the battery. Never top up with diluted sulphuric acid.
- Add distilled water up to the MAX mark.
- Replace the battery caps securely.
Installing the battery
Caution: Only reconnect the battery with the ignition switched off to avoid short-circuiting. First connect positive battery lead (+), fit the positive battery terminal protective cap, then connect negative battery lead (—).
Make sure that the battery breather hose is not kinked or blocked.
Battery acid is highly caustic. Do not permit escaping acid vapour to contact motorcycle components.
- Installation is the reverse of the removal procedure: pay particular attention to the following.
Caution: The motorcycle may only be ridden with the protective cap fitted on the positive battery terminal.
- Guide the breather hose through the eyelet (see arrow) in the battery holder to the outside.
Note: Disconnecting the battery clears all entries (such as errors, adaptations) from the Motronic control unit memory.
The loss of the adaptations may sometimes lead to engine performance being temporarily impaired when the engine is restarted.
Motronic restores the lost adaptations itself over the following operating hours.
- Switch on the ignition.
- Fully open the throttle once or twice with the engine off. Motronic registers the throttle valve position.
Tightening torque:
- Battery tray to battery holder — 4 Nm
