So guys, I did the clutch gasket yesterday, the bike is pretty ready for the 1st of April, a couple of cleaning still to do.
Here are the promised pics (click on them to enlarge) :
The draining of the clutch oil. I used a carton board to have it dripped in a bucket, as I only wanted to empty the clutch container.
1. Where the drip was coming from :
2. The emptying of the clutch lodge :
3. The uncovered clutch :
4. The polishing of the inside of the cover. Here, the old sticking gasket was removed with a very sharp knife-like instrument, being careful not to get any scratches on to it, then, it was polished manually with very thin sand paper :
5. The cover with the new gasket is placed back on the bike :
6. Now just the fairing needs to be put back on the 9, it's a bit of a bitch to do that alone, but make sure you place under the bike a cover or a carton. It will make it easier to slide the fairing under, and will prevent scratches.
The last thing I wanted to point out, is that the replacement of the clutch cover screwing should be done "cross wise", and the pressure applied on the screws of +/- 10 N (Newtons - 1 N = 9.81 m/s²). Now where it is important, is that when you are done re-screwing all the screws, wait between 15 to 30 minutes so that the gasket can rest and "relax". Then, you should do the step of applying again the same pressure on all the nuts to make sure that the pressure is the same everywhere and correctly applied. I used a special instrument which torques when the pressure is reached, so you know you are good.
Now, the meaning of this post is not to re-invent the wheel, but maybe, and this by also posting some pics, only done to help people who have never done it before.
Hope it can be used for other people future use.
