Note
For clarity, the figures show the engine removed from the frame.
Move the piston of the cylinder being checked to tdc of the power stroke: in this condition, all the valves are closed and the timing shafts come in neutral position and, therefore, free to rotate; check to the valve clearance on the cylinder head on which it operates.
Checking the opening clearance
Using a feeler gauge, check the clearance between the opening rocker arm (a) and the lowest point of the camshaft lobe (b), taking care not to compress the rocker arm return spring.
The value must be within the specified ones (sect. 3 - 1.1, Timing system/valves).
If not, remove the opening adjuster (3), as described in paragraph "removing the valves" (sect. 9 - 4.5), And replace it with one of suitable height to obtain the prescribed clearance.
Note
Opening rocker arm shims measuring 1.80 To 3.45 Are available as replacement parts: the size is punched on the shim.
Checking the closing clearance
Using a feeler gauge, check the clearance between the closing rocker arm (c) and the highest point of the camshaft lobe (d).
The value must be within the specified ones (sect. 3 - 1.1, Timing system/valves).
If not, remove the closing adjuster (1), as described in paragraph "removing the valves" (sect. 9 - 4.5), And replace it with one of suitable height to obtain the prescribed clearance.
Note
Closing rocker arm shims measuring from 2.2 To 4.5 Are available as replacement parts: the size is punched on the shim.
Lap registration function
This function describes the "lap" time registration.
If the function is activated (see "lap activation/deactivation
description), the lap time can be registered as follows:
Pressing the flash headlight button (11, fig. 12) The first
time starts the "lap timer" for ...
Introduction to the engine control system
The engine control system used on the diavel consists of the following
elements:
Ride-by-wire system (motorised throttle valves with electric actuator,
throttle grip position sensor and throttle valve
position sensor)
One injector per cylinder installed downstream of throttle valve
On ...
Side stand
Important
Before lowering the side stand, check that the ground
is sufficiently even and firm.
Do not park on soft or pebbled ground or on asphalt melted
by the sun heat and similar or the motorcycle may fall over.
When parking on a slope, always park with the rear wheel on
the downhill sid ...
