- Insert the chain tensioner in the cylinder together
with the gasket and tighten the screws to the pre-
scribed torque.

- Check and restore the correct clearance of the
valves if necessary.

- Turn the crankshaft , acting on the driving pulley
by 270° so as to align the front cylinder timing ref-
erence mark

on the flywheel with the crank-
case reference mark.
- Repeat the fitting operations of the rear cylinder for the front cylinder timing head and components.
Refitting the timing chain
The ignition advance is determined electronically on the basis of parameters known by the control unit.
For this reason it is not possible to declare the reference values based on the engine rpm.
The ignition timing value is detectable any time using the diagnostic tester.
It is possible to check whether the ignition advance determined by the system does in fact correspond
with the value actually activated on the engine, by means of the stroboscopic light.
