Insert the inlet camshaft so that the phase notch on the
conveyer wheel is parallel to the head plane and facing
the outside.
Insert the exhaust camshaft with the notch placed
between the 24th and 25th chain distribution gudgeon,
beginning to count from gudgeon after the inlet
camshaft notch.
Check the correct position of all the O Rings under the
head stands.
NOTE: If the operation is performed with the engi-
ne installed on the vehicle, lift the front wheel until
the axis of the cylinders is in a vertical position.
Position the n°2 and n°3 stands, referring to the num-
bers towards the inlet end;
Position the n°1 and n°4 stands,
Bring the screws together manually hexagonally
embedded.
Chain tensioner
Remove the central screw-cap and withdraw the spring
and the pin.
Remove the screws fixing the chain tensioner to the
head.
Remove the chain tensioner.
Disassembly the chain tensioner and check the correct
working of each part.
The internal pin must run clearly and the inner spring
must give a quick response.
Replace the assembly in case of malfunction.
If everything works properly lubricate the parts and
install the assembly with the chain tensioner in the min-
imum extension position (all in the main body)
Install the chain tensioner body locking the 2 socket
head screws using a T wrench with a 8 N·m torque
Install in this order: the pin in the spring, the spacer and
the screw cap.
Lock the screw cap by hand till you feel the tensioner
extend, then lock it with a 8 N·m torque
Acting this way the chain tensioner is adjusted.
Before tightening stand screws be sure that
the chain tensioner is assembled.
Progressively move the internal hexagonal screws
close. Tighten the screws at a torque of 12 N·m.,
always beginning from n°2 and n°3 stands.
Check to be sure that the valve cap gaskets are in
good condition.
Apply a layer of gasket silicone on the semi moons on
the head in correspondence with the camshaft.
