Torque values changed for engine block,
engine cover and cylinder head,
F 650 GS, F 650 GS Dakar, F 650 CS.
As a result of quality monitoring, BMW Motorrad has determined that
leaks can develop at the engine block and the engine covers.
Engine Block and Engine Covers:
The tightening torque values for
the M6 screws of the engine block and the M6 screws for the engine
covers have been increased.
If the engine shows signs of slight leaks, the engine block and engine
cover screws should be tightened to the new torque value and the
engine tested for leaks.
More extensive repairs should not be attempted unless this initial
measure is unsuccessful.
New Torque Values: 12 Nm.
(increased from 10 Nm)
The new torques values for these M6 screws are noted in the 09/2003
edition TSD CD.

Torquing procedure, cylinder head screws:
BMW Motorrad has
reviewed and redefined the procedure for torquing the threaded fas-
teners securing the cylinder head.
1) The tightening torque of the M8x53 collared screws has been
reduced to a
new specification of 30 Nm, threads free of oil.
The
original specification was 33 Nm, threads free of oil.
Important Note: Under no circumstances is oil to be applied to the
threaded fasteners. If in doubt about the status of the collard
screws, install new parts.
2) The cylinder head gasket has been modified: The new cylinder head
gasket has been modified with the addition of two extra beads. They
prevent engine oil from entering the bores for the engine stud bolts.
