So, why the need to do this?........
No need to say anything more! (picture courtesy of BrianUK)
Torque settings:
GPS retaining bolt - 6.5 N-m / 4.7 lb-ft
Crankcase bolts - (M6) 11 N-m / 8 lb-ft (M8) 26
N-m / 19 lb-ft
Sensor rotor Allen bolt - 20 N-m / 14.5 lb-ft
Engine sprocket nut - 115 N-m / 83 lb-ft
Use of 'Thread Lock' compound on all threads is recommended

This is a quick guide on how you can check your speed sensor rotor
nut Allen bolt for security. This should not be used over and
above going to your dealer and having them check the bike. If you
are unsure about using tools go to your dealer. If you feel
reasonably confident then you can do this to put your mind at rest.
There are two bolts that hold the clutch release cylinder in
place.
In this diagram you can see their location.
(1) is the upper bolt with a spacer (2) behind it.
(3) is the lower bolt.
Undo these bolts and carefully remove the clutch release cylinder.
Once removed do not touch the clutch as this will force the
cylinder out of place.
Here is a picture of the bolts and spacers.
Notice that bolt numbered (1) is longer than bolt numbered (3). Bolt
number (1) fits in the top of the clutch release cylinder with the
spacer behind it.
You should now see the engine sprocket cover as per the diagram
below.
This is held on by three Allen key bolts (1), (2) & (3). Notice that
bolt number (1) has a metal tab that holds the gear position sensor
and speed sensor cables in place. These need to be free.
(4) is the clutch push rod and can stay in place for now.
(5) is the mounting lug for the clutch release cylinder - mine was
slightly corroded and therefore needed cleaning. It also hindered
smooth removal of the clutch release cylinder that needed some
persuasion
Undo the three bolts, unfold the metal tab and remove this cover.
Here are the sprocket cover bolts.
Note that bolt number (1) is longer than the other two that are the
same size (2) & (3). You can see the fold over cable tie on bolt
(1).
Now with the sprocket cover off you should see the speed sensor
rotor nut and more importantly, the Allen bolt that has caused all
of the problems.
This is the bolt (1) that you need to check is tight, really tight.
If this bolt comes undone it will work it's way out and split the
sprocket cover as reported elsewhere on this site.
Once tightened, replace everything in the order you took it off and
give it all a clean in the process - it will be very messy with
chain lube everywhere - yuk.
