O-ring chains have sealed, life-lubed link studs and bushes. However, these chains need lubricating at regular intervals to protect metal parts of the chain and the o-rings.
Lubrication also serves to keep the o-rings soft and pliable to ensure the maximum sealing efficiency.
Using a brush, apply a thin protective layer of high-density gearbox oil along the entire length of the chain both inside and outside (sec. 3 - 2, Fuel, lubricants and other fluids).

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

Refitting the steering head components
Important
The steering tube bearings (6) are identical but in no case may their
components be swapped around during reassembly.
Clean all contact surfaces and lubricate with the recommended grease.
To fit the external rings (c) of the bearings (6) to the steering tube, use the
tool with par ...
Refitting the oil pump
If removed, apply specific threadlocker on the bushing (7) outer thread, and
screw it in the crankcase half, observing the
height.
Position the reference bushings (15) and the oil sealing o-rings (2) and (4)
according to the crankcase lubrication
channels.
Position the oil pump on th ...
