Make the rear wheel turn until you find the position where chain is tightest. Set the vehicle on the side stand. Push down the chain at the point of measurement and release. Measure the distance between the "aperture" upper profile and pin centre.
The read distance must be: 9 to 11 mm.

Important
If the drive chain is too tight or too slack, adjust it so that tension reading will fall within specified range.
To adjust the tension remove the rear splash guard (sect. 7 - 13, Removal of the swingarm).
Slacken off the two clamp screws (1) that secure the rear wheel hub to the swingarm.
Fit the hook spanner code 88713.1038 Inserting its tooth in the eccentric hub (2).
Rotate the eccentric hub (2) to obtain the correct chain tension.
Turn counter clockwise to tighten the chain; clockwise to loosen (from chain side).
Important
An incorrectly tensioned chain will lead to accelerated wear of the transmission components.
If the screws (1) are removed, lubricate with specified grease underhead and thread, then tighten the screws (1) to the torque of 35 nm +/- 5% (sect. 3 - 3, Frame torque settings) proceeding with sequence 1-2-1.

Warning
The correct tightening of the fixing screws of the eccentric hub is essential for the safety of the rider and the passenger (sect. 3 - 3, Frame torque settings).
Refit the rear splash guard (sect. 7 - 13, Refitting the swingarm).

Introduction
The engine control system of the diavel is equipped with an inductive sensor
that allows the ecu to determine the speed
and timing phase of the engine. The sensor faces a phonic wheel with 48 teeth
minus 2.
The engine speed-timing sensor is an inductive sensor and faces a 48 ...

Refitting the camshafts
If the stud bolts (2) were removed, apply the recommended threadlocker to the
short end of the stud bolts (2), i.E. The
end that is to be screwed into the cylinder head. Tighten the stud bolts (2) to
a torque of 10 nm (min. 9 Nm - max. 11
Nm) (sect. 3 - 3, Engine torque settings).
