Checking and adjusting the throttle cable play
You should feel 3-5 mm free travel on the throttle grip when you start to turn it.
To adjust, slide back the protection cover [1], loosen the counternut [2], turn the adjusting
screw [3] as required and tighten the counternut again.
Make sure that the throttle grip will return to the idle position automatically once you let go
of it.
To check the correctness of this setting, start the engine, turn the handlebar left and right,
in both cases as far as it will go. This must not cause any changes in idling speed. Otherwise,
you have to increase the backlash of the throttle cable.
Checking and adjusting the choke cable play
The choke cable must have a play of approx. 3 mm (0.12 in) at all times. To check the play,
push back the protection cover [4]. It should be possible to lift the cable approx. 3 mm away
from the adjusting screw [5].
If necessary, loosen the counter nut [6], turn the adjusting screw as needed, tighten the
counter nut again and slide on the protection cover.
If there is no play in the choke cable, the bore of the cold starter system cannot be com-
pletely closed. This will result in high fuel consumption, irregular engine operation, extreme
wear on the pistons and cylinders and will destroy the catalytic converters.
Adjusting the engine idle speed
The idle speed should be 1400 rpm when the engine is warm. The idle speed can be adjusted
with the adjusting knurl [7] near the left frame tube. Turning in a clockwise direction will
increase the idle speed, turning in a counterclockwise direction will reduce the idle speed.
