cover. For this purpose, remove bolts
1 and cover together with the
rubber boot

should be 4 mm (0,157 in) below the upper edge. If necessary add
SAE 10 biodegradable hydraulic oil (Motorex Kupplungs-Fluid 75).

Adjusting the throttle cables
The throttle grip should always provide for a backlash of 3-5 mm.
Besides, with the engine running, the idling speed must not change if
you turn the handlebar all the way to the left or right.
To adjust the throttle cables, dismount the seat and the tank together
with spoilers. Slide back the protection cover
4. Loosen the counter
nut
5 and turn the adjusting screw 6 accordingly. Turning the
adjusting screw counterclockwise will reduce the backlash, turning the
adjusting screw clockwise will increase the backlash.
Tighten the counter nut and check whether the throttle grip can be
actuated smoothly. Mount tank and seat.
– After a short, careful test ride, check engine oil and coolant level
once more.
