4.8.10 CYLINDER SYNCHRONIZATION
Carefully read 0.5.1 (PRECAUTIONS AND GENERAL
INFORMATIONS) and 1.2.1 (FUEL).

for the maintenance intervals, see 2.1.1 (REGULAR
SERVICE INTERVALS CHART).
INTRODUCTION
The synchronization of the cylinders depends on the
compliance with the following conditions:
a) Engine idling speed:
– 1250 ± 50 rpm ;
b) CO values in the cylinders: (*1)
– non-catalytic version (excluding
u
) from 0.8% to
1.3% ;
– catalytic version (excluding
u
) from 1.5% to 2.0%;
– catalytic version
u
from 1.5% to 2.0%;
c) Vacuum values in the cylinders: (*2)
– 300 ± 30 mbar.
(*1) A difference is accepted for the CO values: of cylin-
der “1” (front) and of cylinder “2” (rear).
(*2) A difference is accepted for the vacuum values: of
cylinder “1” (front) and of cylinder “2” (rear).
NOTE
To obtain the synchronization of the cylinders,
adjust the above mentioned values repeatedly, always
following the given order.
NOTE
The adjustment of one of the three values may
cause the incorrect modification of the other two values,
therefore after any adjustment it is advisable to check all
the three values.
The CO value takes priority over the vacuum value.
◆
Check the engine number, see 1.1.2 (ENGINE
NUMBER), and choose the suitable procedure accord-
ing to the result of this check.
NOTE
From engine # 686065. . To allow the check of
the cylinder vacuum values, the throttle body is equipped
with the special coupling (1) and therefore it is not neces-
sary to replace the intake flange with the vacuometer
socket (2)
NOTE
From engine # 686065. DO NOT carry out the
operations marked with the symbol “
✖
”.
NOTE
Have the appropriate special tool
m
to hand:
– aprilia part# 8140267 (intake flange for vacuometer)
(2);
– aprilia part# 8140256 (vacuometer) (3).
◆
Lift the fuel tank, see 2.8 (LIFTING THE FUEL TANK).
