This week-end I had some time to work on my swingarm.
I tried Paulbrice's way of putting a wooden plank beneath the sump and lift the bike from there but it was way too unstable for me. I don't know if it was due to a not completely level floor or a different weight distribution on a 2v than a 8v but there was no way I would thinker on the bike in those conditions!
I ended up putting together the stand shown here by Kiwi_roy with my very limited wood working equipment. Not the prettiest but it did the job. [You must be registered and logged in to see this image.][You must be registered and logged in to see this image.]
The whole procedure went relatively smoothly. The CARC unit had no sealant on the interface and the bolts were in a very good state. I followed Pete's advice to add some loctite 290 on the pinion threads and let the CARC unit sit overnight. [You must be registered and logged in to see this image.]
In the meantime, I removed the rest of the swingarm and pulled out the bearings. They had no grease on them but were in good state even though that service was never made and the bike has 36K km. I cleaned them well and then added plenty of grease on the bearings and the races. [You must be registered and logged in to see this image.][You must be registered and logged in to see this image.]
While the bike was dismantled, I also took the occasion to remove the old shock and grease the needle bearings (dropping none!) in the suspension assembly.
The rubber button that absorbs the energy when bottoming out was completely destroyed on my stock shock![You must be registered and logged in to see this image.]
I then fitted the 2nd had stelvio shock that was delivered to me 2 days ago. I had a short panic attack when trying to align simultaneously the bottom eyelet of the suspension with the swingarm and the carc eyelet with control arm. The shock seemed too long for both locations to align at the same time. All went well though when I realized that the CARC eyelet can move and allowed the swingarm to lower enough to fit the longer shock. I set the prelaod to 15 clicks from fully unwound and the compression dampening to 24 clicks form fully closed. I will have to ride more to tune it.

The rest of the reassembly went very smoothly. I had to tighten the preload bushing by feel as I did not have a castle tool and used a C-spanner. I'll keep an eye on that.
Finally, I used the fact that the bike was on the stand to change the engine oil. The filter was a pain in the ass to access and remove. How the hell do you do that with so little clearance ?! I added 3.2L of oil (manual says 3.6L). I'll ride a bit and check the level again. Is the v2 like the v8 in the sense that it's better to be closer to the MIN mark than the MAX one?
Thanks everyone for all the infos that you provide on this forum. I would never have tried (or though about) that otherwise. Now it seems that the weather will finally be better in the coming week so that I can try all thew new improvements!
