Adjusting the throttle cable *
When starting to turn the throttle grip, you should feel an initial backlash of
3-5 mm.
If a correction is necessary, start by removing the tank. Slide back the
protection cover
1 . To set the backlash, loosen the counter nut 2 and turn
the adjusting screw 3 accordingly. Then, fasten the counter nut and slide
the protection cover back on.
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.
Draining the carburetor float chamber *
Following every wet-cleaning procedure, the float chamber of the
carburetor should be drained in order to remove any water that may have
penetrated into it. Water in the float chamber causes engine malfunction.
Carry out this job with the engine being cold.
Close the fuel tap.
Put one end of the hose
4 that leads downward behind the engine into a
collecting vessel.
Open the drain plug
5 (turning it counterclockwise) by several turns, and
drain the fuel from the float chamber.
Then, retighten the drain plug and open the fuel tap.
