ADJUSTING THE EXHAUST PORT VALVE
"ELECTRONIC RAVE" (Fig. 44) (only for
the standard version)
Read page 50 carefully.
The opening and closing of the exhaust port valve
"RAVE" are controlled by a solenoid which, when ex-
cited, attracts a magnetic core connected with a ca-
ble that acts on the valve.
In order to ensure the proper functioning of the sys-
tem, it is necessary to adjust the cable stroke careful-
ly, proceeding as follows:
– Loosen the adjuster nut (1).
– Unscrew the adjuster completely (2).
– Pull the cable (5), pushing the core (3) inside the
solenoid (4). The core (3) will not enter completely.
In this way the cable (5) is under traction and the
RAVE valve is completely open.
– Keeping the same traction on the core (3), screw
the solenoid adjuster (4) almost completely (leave
about 0,5 mm before the end of stroke).
– Tighten the nut of the adjuster (1).
– To verify if the operation has been correctly per-
formed, make the core (3) go back inside the sole-
noid (4), then let it go out slowly, accompanying it
with the hand to its rest position.
– In this condition the distance must be included be-
tween 7,5 and 8,5 mm.
