Adjusting the throttle cable (Mikuni carburetor)*
When starting to turn the throttle grip, you should feel an initial backlash of
3-5 mm.
For models outfitted with the throttle twist grip depicted in the illustration,
the throttle cables have to be adjusted at the carburetor.
If a correction is necessary, start by removing the tank. Slide back the pro-
tection 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 (Mikuni)*
Following every wet-cleaning procedure, the float chamber of the carbure-
tor should be drained in order to remove any water that may have penetra-
ted 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.

Draining the carburetor float chamber (Dell’Orto) *
Following every wet cleaning procedure, the float chamber of the carbure-
tor should be drained in order to remove any water that may have penetra-
ted into it. Water in the float chamber causes engine malfunction.
Perform this task on a cold engine. Close the fuel tap, and place a cloth
underneath the carburetor, which is able to absorb any escaping fuel.
Unscrew the plug
6, and clean it with compressed air. Then, mount the
plug together with its gasket, open the fuel tap, and check the float cham-
ber for any leaks.
