Just after my 30 000 km service,I noted that when in 3rd gear and accelerating hard , the clutch slipps slightly.
I called the dealer to see if there was any Technical reports from the factory in that regard, the answer was no,your clutch must be going.

Sorry , I didnt accept that , so I removed the side cover and carefully removed all the friction and stator plates,
I measured all the friction plates in accordance with the manual( There are 3 different types of friction plates that make up the clutch , just by the way)

All were still in spec.

Right now for the clutch springs.
55.2 mm to 52 mm.

Well they range between 54 to 54,4 mm.
So I have added 1mm shim washers on the top of the springs , just under the attachment screws.
Beware of putting them at the bottom under the springs .
The shims I first used , had a slightly smaller center ID and the got stuck on the aluminum attachment posts.
Anyway , all assembled the cluch feels much better than before.
Doing a 500km ride in the mountains tomorrow , so we shall see
