Inspections I and III
- Open the throttle twist grip fully at different handlebar positions and then release.
- Turn the handlebars to full left lock.
Models without cruise control
- Preset throttle cable play with the engine cold to 1.5 mm (0.06 in).
Warning: Observe the hazard avoidance instructions for running internal combustion engines in enclosed spaces.
- Warm up the engine to its normal operating temperature (radiator fan starts to run).
- Adjust throttle cable play to 0.5 mm (0.02 in).
Setting:
- Initial throttle cable play setting (engine cold) — 1.5 mm (0.06 in)
- Throttle cable play (engine warm) — 0.5 mm (0.02 in)
Models with cruise control
Throttle-opener cable, throttle-closer cable
Note: The throttle twist grip must not be tight against the stop on the handgrip in the idling position. It must be possible to turn it a further 10° in the close direction against a slight spring force. This actuates the cruise-control system switch on the throttle valve. The throttle twist grip has to be turned relative to the throttle-body shaft if this extra rotation is not possible.
- Remove the left side section of the fairing.
Caution: Make sure the cables do not slip out of the adjusting screws as this could cause damage to the cables.
- Preset the play of both cables at the throttle twist grip to 4...5 mm (0.16...0.20 in) with the engine cold.
Warning: Observe the hazard avoidance instructions for running internal combustion engines in enclosed spaces.
- Warm up the engine to its normal operating temperature; radiator fan starts to run.
- Reduce play of throttle opener cable (1) to 3 mm...4 mm (0.12 in...0.16 in).
- Turn throttle twist grip just enough to take up play at throttle opener cable and adjust play of throttle closer cable (2) to 1 mm (0.04 in).
Settings:
- Initial setting (engine cold) 4 mm...5 mm (0.16 in...0.20 in)
- Total play of both cables at throttle twist grip (engine warm) 1 mm...1.5 mm (0.04 in...0.06 in)
Cruise-control system cable
- Adjust play of the cruise control cable to 2...3 mm (0.08...0.12 in) using the adjusting screw on the clamping sleeve (arrow).
- Check the freedom of movement of the throttle twist grip. When released, the twistgrip must return to the closed position by itself and with an audible click.
- Check the routing of the cables if the throttle twist grip does not return to the closed position or if it is stiff.
- The play on the two cables can also be increased if the throttle twist grip is stiff. Do not exceed a total play of 1.5 mm (0.06 in) at the throttle twist grip.
Settings:
- Cruise-control system cable 2...3 mm (0.08 in...0.12 in)
Turning the throttle twist grip relative to the throttle valve shaft
Note: The throttle twist grip must be turned relative to the throttle valve shaft if the switch for the cruise control on the throttle valve is not functioning correctly.
Cruise control system does not switch off
- Increase opener cable play.
- Reduce closer cable play by the same amount.
- Check the operation of the throttle twist grip. When released, the twistgrip must return to the closed position by itself and with an audible click
Cruise control system cannot be set, or continually shuts down
- Increase play on throttle opener cable to a maximum of 1.5 mm (0.06 in).
- Increase play further, if necessary, to check the operation of the microswitch and the actuating mechanism on the throttle valve rail.
